Nintex Automation K2

We just upgraded K2 from version 4.6.6 to 4.6.11 on our environments. There are two K2 servers in the environment with a load balancer setup. After the upgrade, some of the functions from K2 workflow API are throwing exceptions."Error","EnvironmentServer","15100","Generic","SourceCode.Workflow.Runtime.Management [OpenConnection [string[] names]]","15100 Error occurred, ERROR: Unable to connect to loadbal-k2-abc.com on port 5252.

hi,I have a REST service which needs an json array as an input. Like:{ "array" : [ { "value1" : "abc", "value2": 1.00 }, { "value1" : "def", "value2": 2.00 } ]}The SmartObjects method gets an Memo input parameter (requestarray). I think I have to expose this input parameter as a list with the serialize list function of the requestarray.I know how to deserialize response values, but I couldn't figure out how to do it on the input side. Is there a tutorial somewhere? 

Hi, I've created a Endpoints Webservice instance pointing to a wsdl and can successfully connect. I've also created a basic SmartObject in order to test the service. However, when I try execute the SmartObject method, I get a HTTP "417 Expectation Failed" error straight away. Having done a little reading, I tried to amend the web config so as not to send the Expect: 100-Continue header, but this has seemed to make no difference. Has anyone else run into this issue before? Any ideas?

when Rest API smartObject executed, in response it is returning back blank values. and the response code is 0.   I have also tried with openweather API it shows same result.   PFA screen shot.   When I tested Rest API and the JSON descriptor document also in POSTMAN client, Response code is 200. test is successful.   but not able to understand from k2 why it does not returning expected result. Guys, Kindly let me know how to resolve it. I will really greatfull for your technical help.

We have created a Swagger (file attached) Rest Service instance with Smart Objects, however on a view when running Serialize then GetData method the HTTP response code this is coming back as error 415. In the service instance I have now added in the default HTTP response headers the below so this knows that this is JSON: {"$type": "SourceCode.SmartObjects.Services.Endpoints.Common.HttpHeader[], SourceCode.SmartObjects.Services.Endpoints.Common, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null", "$values": [ { "$type": "SourceCode.SmartObjects.Services.Endpoints.Common.HttpHeader, SourceCode.SmartObjects.Services.Endpoints.Common, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null", "Name": "Accept", "Value": "application/json" }, {"$type": "SourceCode.SmartObjects.Services.Endpoints.Common.HttpHeader, SourceCode.SmartObjects.Services.Endpoints.Common, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null","Name": "Content-Type","Value": "application/json"} ]} However this then

hello, how I can show the (originator/Created by) in the worklist Control and i can extend worklist (add another column )  

If i run listview using runtime url it is showing total number of page as below -  When i used same view as popup in form total number of page is not displaying on view, it is going below. I am using Lithium theme in the form. I tried to add style to move total count next to 1 as shown in image 1 but not success.  If anyone is having idea on it, please let me know. Thanks in advance.

Does anyone know how to autofit a button size based on text in the button (or wrap button text) and the column around it? I have buttons on my form, whose text changes based on the task and it keeps cutting off half of it. Furthermore, on differing computers the buttons sometimes get half cut off based on screen size.  Any help would greatly be appreciated.

Hi All,I'm integrating with a Web Service provided by a 3d party and I don't have control over the web service.They provided a swagger file and an extract of the swagger for the method in question is below as an example.There are some optional fields but the Web Service has a requirement that the field needs to be specified with a null value.When I don't specify a value for one of the fields from the K2 smartobject (or even pass scnull), K2 does not include the property in the payload instead of specifying it as null, see below.Is there a way I can force K2 to specify the property in the JSON payload with a null value rather than leaving it out? Swagger: "AddWorkflowStepV2Request": { "title": "AddWorkflowStepV2Request", "description": "#### Add a step to the Workflow request.", "type": "object", "properties": { "ActionField": { "description": "#### Is the action taken by a user in a workflow on this step.`", "type": "integer", "format": "int32", "enum": [ "0", "1", "2" ] }, "CellField"

K2 Five 5.2 Designer We are currently in the midle of building a very complex workflow with several steps. After many successfull deployments, we are now getting this error which prevents deployment. The error message, as always, is quite opaque. Any ideas on what the issue is? What is systemName and why is it null? How can we correct? 

Hi, i created and deployed custom control with one property MaxValue. <Prop ID="MaxValue" friendlyname="MaxValue" type="string" category="Detail" refreshdisplay="true" mappable="true"><Value>100</Value></Prop> how can i update that value from javascript so that after updating i can see that value from any k2 rule.  i have setproperty function in js but its not working. (after updating showing old value in k2 rule) setProperty: function (objInfo) {//console.log(objInfo);if (objInfo.property == "Style") {CustomControls.Guage.setStyles(null, objInfo.Value, $('#' + objInfo.CurrentControlID));}}, 

At runtime, I need to be able to check if a process instance is active with a specific folio (not necessarily assigned to the current user). At minimum, a true/false response is enough. Is there a way I can query for this in an efficient manner using system smartobjects?   Note: Calling a list method to return all process instances for a workflow and filtering is not an option since this specific workflow would have thousands of active instances and filtering on the result set is very inefficient.

Hello,I'm trying to implement a "Get confirmation from user" action on a static drop-down list populated with three static values (empty value allowed). Whenever the user changes the DDL value, a confirmation message dialog shows to the user with "Ok" or "Cancel" options. When the user validates, everything works fine, but the issue is when I hit "Cancel". As the message dialog shows on "When View Control is Changed" event, the new value is set behind the message even before hitting "Ok", so even if I decide to hit "Cancel", it doesn't go back and keep the initial value, but it instead keeps the new one. Has anyone faced this problem? Any help would be appreciated 🙂  Thank you, Amine

It is currently a brand new non-domain installation of K2 Five 5.5.When K2 Five 5.5 was installed to the "App Framework Core.kspx" progress, an error occurred, which prevented the installation from continuing.From the error log, it seems to be related to session authentication, but it is not an error at the beginning.Try to implement other related solutions, but did not succeed:KB002419https://community.nintex.com/t5/Technical-Issues/Known-Issue-App-Framework-package-fails-during-upgrade/ta-p/123937KBT146714https://community.nintex.com/t5/How-To/quot-Authentication-Required-for-Session-quot-error-appears-on-P/ta-p/125090I tried to manually install "App Framework Core.kspx" using a different connection string or a different Windows account, and the errors I got are as follows:(Execute K2 Package and Deployment tool deployment on other computers, and get the same error)Runas local Administrator:D:K2K2 Five (5.5) (5.0006.1000.0)Installation>DeployPackage "D:Program FilesK2\SetupApp Fra

with .net core 2.1 end of live date of later this year, will the k2 5 requirement of having 2.1.7 installed be changed to .net 5?  Will updating .net core to 5 on a k2 blackpearl server break K2?
