The function is used to populate a reporting list from a customized SmartObject. However, when the button is clicked, K2 throws the error “An existing connection was forcibly closed by the remote host”, and the reporting list cannot be displayed.This issue occurs only at the K2 application level. When I execute the SQL script directly against the database, it completes successfully and returns 86 rows.

Hi Community Team,Our team is currently working on a Proof of Concept (POC) using Nintex Automation K2 5.9 (On-Premises), Build 5.0010.1000.0.As part of this POC, we are attempting to retrieve multiple records from Google Sheets through a SmartObject and process each row individually using a K2 Workflow Loop.1. Current ScenarioWe have successfully established a connection to Google Sheets and retrieved the spreadsheet data using a SmartObject.The Google Sheets response contains multiple rows in the following JSON structure:{  "range": "Pricing!A2:B4",  "values": [    ["DocGen", "RM20,000"],    ["Nintex Workflows", "RM15,000"],    ["Process Manager", "RM25,000"]  ]}Each nested array represents one record consisting of two columns:Column A: Product Column B: Price2. Expected ResultWe would like the K2 workflow to iterate through each Google Sheets row and process the Product and Price values separately.For testing purposes, we have configured a Send Email step within the Workflow Loop to

I have two views in a K2 SmartForm (automation on premise), where I need to use onchange event for two add/edit fields, but it get me some issues… On the Onchange-events, an advanced smo-object method  gets data from an external api, and fill up the add/edit rows in the view.On the first onchange-event, it gets data for the field, that also have an onchange-event on itself… → When x is filled in - get y, and the opposite, plus other fields.The events triggers not only once, but several times, and other errors shows, when both the rules is enabled. Someone that have done anything similiar, and have any solution to the problem/-s?I get problems with how many times the event triggers, andI get an error, that I can’t find (can’t convert string to timespan..),which should in some way be related to the events , because it disappears, when I just run one of the onchange- events.  The - When the view executed List item added , is triggered when user clicks another row…, and a rule on the form

We have Cybersecurity Emergency Patch Alert: Critical Vulnerabilities in K2 Five CVE-2026-111497, We want urgent support on this.

I’ve noticed this a lot across all of our servers lately.  K2 5.9 FP13 and later. It happens after a server restart or an IIS Restart.  Antimalware Service Executable often causes CPU to go to 100% for about 5-10 minutes and K2 Management says Smartform warming up and the timer keeps resetting.  About 50% of the time after that K2 Management will not work after the restart with an error similar to the one below. Server ErrorCould not load file or assembly 'SourceCode.Forms.Controls.Web.ControlPack.Choice' or one of its dependencies. The system cannot find the file specified.(http 500 error)Refresh Page? Redoing an IIS Restart will eventually work but in the meantime its another 10 minutes of downtime. I’ve been querying possible solutions like excluding temp directories and such but the only thing that seems to work in testing is excluding w3wp.exe.  However that doesn’t appear to be a secure solution.  Any recommendations?

Hi,I have recently upgraded K2 from 5.6 to Nintex automation(5.7).after upgrade, AD group users are not resolving in K2.anyone has an idea, please assist.Best Regards,Thriveni  

I have a question about the text in Watermark, which appears in many controls. In the views, the text is shown in italics, but in the form the italics disappear. How can I get the italics in the form as well? I use the Style Profile. If I select the old .css file, it works fine, but we want to deprecate it.

I have upgraded Nintex Automation K2 from version 5.6 → 5.8 → 5.9.The upgrade completed successfully without any errors.The web site is running normally, and users can: Create SmartForms Run workflows successfully However, I found an issue after the upgrade:When I try to log in with some test users (for example: k2test1), they cannot access the Workspace page(e.g. https://k2test.xxxxx.com/workspace).The following error message is displayed: Not authorizedYou do not have permission to view the page that you have requested.The administrator of this SmartForms environment has restricted access to this page.If you believe that you should have access to this page, please contact your SmartForms administrator. Important details: k2test1 is a normal user (no special permissions) Before upgrading to K2 5.9, this user could access Workspace normally After testing multiple users, I found that: Some users get "Not authorized" Some users can access Workspace without any issue No c

Hi everyone! I have 2 custom controls which problems right now. Is it necessary to have .aspx format file for custom control? Do you guys know how to solve this issue? All the forms and views that are using these custom controls cannot be opened. This is custom control .dll files that are impacted:1) K2Field.ListSequenceDisplay.dll2) K2FormProgressSteps.dll  

On-Prem K2 5.9, using on-prem AD as user manager.Currently K2 API website is load balanced via AWS ALB (which has problem with Kerberos), would need to switch to NLB, but K2 documentation doesn’t mention supporting Windows Auth for the REST API calls.Is there a plan to support OKTA for Oauth?This is specially for the Tasks API.Alternative is to build a separate API using the .NET 4.8 SDK...

Hi everyone,I'm currently building a workflow in Nintex K2 and would like to generate a PDF document from a Word template, similar to the Generate Document feature in Nintex Workflow Cloud (NWC).For example:K2 SmartForm → Workflow → Populate Word template → Generate PDF → SendIs this feature available in Nintex K2?If not, what is the recommended way to achieve this in K2? If there is a guide or example that I can follow, I would really appreciate it.Thanks!

Hi all,I want to ask regarding the generate document feature that exists on NWC. Does it work on Nintex K2? Because I need to generate document from template. I know this feature works on Nintex Cloud because I’ve used it before, how about K2?

when I press enter, although my textbox has value but it cant pass to value to my Smartobject but same input when i click to other place or press tab it will show the correct stepwhat i do for this is when user key in the asset disposal number, it will pass the number to the smart object and return true or false value. once the data label change, it shows true value, the system will block. the correct example shows at 2nd picture.however, if the user press enter, this validation will not work

I just wanted to gauge people’s opinions and experiences with the newer K2 Workflow Designer.We’ve had so many problems with K2 Studio workflows over the summer, including issues with what should be very basic functionality. For example, hyperlinks in an email body are no longer being accepted in some of our workflows, resulting in failed workflows with errors stating that there is no connection string for the destination user. Remove the hyperlinks from the email and the exact same steps work perfectly. The errors don’t even match the issue...When we raise tickets with K2, we’re told that development of K2 Studio workflows is no longer supported because it is considered legacy, and the recommendation is to move to the newer Workflow Designer.Fair enough — so I’ve been trying to migrate some of our existing workflows to the new designer.Unfortunately, the experience so far has been extremely poor.Window panes regularly freeze or become unresponsive. When editing an email body, if you e

Hi everyone,I’m currently developing a workflow in Nintex K2 and I need the workflow to retrieve data from a SharePoint Online list.I’m quite new to K2 and I’m not sure what the correct integration/setup process is between K2 and SharePoint.My requirement is basically:SharePoint Online List → K2 → SmartObject → K2 WorkflowI would like to use the SharePoint list data inside the workflow, for example to retrieve/list items and use the column values in the workflow.I have access to K2 Management, and I can see SharePoint-related Service Types such as SharePoint Site Collection and K2 for SharePoint, but I’m unsure which one should be used and how it should be configured.My main questions are:What is the recommended way to connect K2 to an existing SharePoint Online site/list? Do I need to create a Service Instance in K2 Management using the SharePoint site URL? Which SharePoint Service Type should be used? What authentication method should be configured for SharePoint Online? Does K2 for

We recently migrated a K2 5.9 FP14 system from EWS Online to Graph and noticed issues with mails.The mails for tasks and redirects are not going through but email action ones are, has anyone had a similar issue with Graph and found a solution?We checked the HostServer and Event View logs, but no errors are showing up.

Hello,I’m using translations based on the ui-culture URL parameter. The translations work correctly for Forms and Views, but I’m having an issue with translating subviews.I have already added the translated keys in the Management environment, but I’m unable to see the language switch for subviews when I change the ui-culture parameter in the URL.Could this be related to how K2 handles translations? Does K2 load translations only when initializing the Views/Forms that are directly visible to K2? Is it possible that subviews are loaded using lazy loading, so their translations are not initialized when the ui-culture parameter changes?Is there a recommended solution or workaround for this type of issue?Thank you!Regards,

Hello Community! I like the way Radio Button controls look when the “Borderless” property is checked, but I’ve found that if the radio button is required, the validation rules don’t give it a red border because, well, it is borderless. How do you all let users know that a borderless Radio Button control is required?

Hello community - I’m getting user complains that the icon to expand/collapse views on the form are too small and difficult to click. In the legacy theme, I was able to come up with some JQuery to make the entire view header clickable to expand/collapse the view, but I’m having a hard time doing the same with the modern theme (K2 5.9). If anybody else has solved this issue, would they be willing to share their script (or other approach)? Thanks in advance!

Hello Community - how do you all validate non-required calendar controls on your K2 forms? I’ve found that if the user manually types in an invalid date, the form does properly highlight it but it still passes the validate condition because the value behind the scenes in the control is blank. This is find for when the field is also required, but if it is not there is no way for the form rules to know that the control has invalid data. I’ve ended up building some javascript to see if any calendar control has that invalid class on it and set an is valid checkbox accordingly, preventing the user from saving/submitting if this check box is not checked. That seems like a strangely convoluted work around for what seems to be a simple issue. Am I overlooking something? Please share your solutions to this scenario. Thanks!

HiBecause of the upcoming deprecation of Exchange Online EWS I’m testing moving our environments over to using MSGraph.I upgraded to 5.9 successfully.  Ran the Exchange Online Migrate wizard successfully and email works.  However, it appears when I look at the Connection String editor for mail configuration that its still using EWS as it didn’t add the MSGraph settings.  I checked and the Azure Enterprise app was added successfully with the correct permissions.  The resource shows correctly in Management.  I tried following the article about manually configuring some of the connection string settings but email then failed.   Is the Migrate wizard supposed to take care of all of the settings or am I missing something?  I’ve restored the VM and retried 4 times so far without any luck. https://help.nintex.com/en-US/nintexautomation/icg/5.8.1/Content/Configure/ExchangeOnline/ExchangeOnlineManual.htm

Hi everyone, I would like the external users to receive the eform from the email notification. In k2, can we do that? I mean no need to login into K2 environment. They can open the page directly from email.

Hi everyone.Do you guys use K2 mobile? I saw the view page in K2 mobile looks like squishing. Does resize the form is the only solution?
