 Symptoms  Receive the following error when running workflow with SmartObject event that executes a load method which returns XML data then assign that data into Process XML data field. "Expression must evaluate to a node-set."  Diagnoses  The issue has been identified as a bug in the product and will fixed in the future release.  Resolution The workaround is to assign the result XML from SmartObject into a String data field first then using a separate data event to transfer value of that string data field into the xml data field then that seems to work ok.   

Question from another user: I am new to the community. I have a Nintex platform set up to tie into our corporate On-premise sharepoint. I am trying to use the Nintex mobile app. When I am on the plain old internet everything works fine. When I try to use the Nintex Mobile application on a device hosted on our corporate network (firewalls / proxy) I get a cannot reach server when I try to do something like "refresh forms".Two quick questions (hopefully).What are the networking requirements for having the Nintex mobile app reach the Nintex live cloud?Where on the device (if anywhere) is the client application's error log.

Within Task Notification, I can insert various URLs and Display Names, but I'd like them to be combined, so that the Display name is the link and the user does not see the actual URL.  How can I do that?Also, similar problem - When I add/move text within my Task Notification, I seem to "lose" the proper link.  For example,  when I initially use an action that contains a Task Notification, there is a link to "Context Item Display Name" which works fine.  But when I add text before and after it, and move text around, I "lose" the link and the notification only shows the actual text of "Context Item Display Name".  How can I get the name/url back?

Hi,Recently we needed to uninstall Nintex Workflow from our Sharepoint 2013 server. Unfortunately, after completing official uninstallation guide, Nintex left some orphaned Event Receivers entries in Central Administration’s database, which are causing errors and issues with publishing in Sharepoint. Is there any way to safely remove those objects? I assume simply removing it from database is not the best idea. Below received error from test-SpContentDatabase on Central Administration database:Category        : MissingAssembly Error           : True UpgradeBlocking : False Message         : Assembly [Nintex.Workflow.Features, Version=1.0.0.0, Culture=                   neutral, PublicKeyToken=9(…)2] is referenced in th                   e database [SharePoint_AdminContent_2(…)3], but is not installed on the current farm. Pleas                   e install any feature/solution which contains this assembly.

 Symptoms During the execution of a workflow involving a SharePoint library, K2 for SAP and an External Web Service, a ?request timed out? error is encountered. Client is trying to pinpoint where. According to a SAP consultant the document does get uploaded although they receive a timeout. Client already increased the timeout according to this article: https://help.k2.com/kb000552 Diagnoses From reviewing the K2 Hostserver Log file, the following error was observed: "An error occurred in the [ExternalWebServices] Service Instance. The operation has timed out". This indicated a timeout occurring on the External Web Services used by a SmartObject. Resolution The client was requested to increase the "executionTimeout" and "maxRequestLength" value in the Web Servive web.config file. e.g.Please see the following Microsoft Documentation for reference: https://msdn.microsoft.com/en-us/library/e1f13641(v=vs.90).aspxAfter the limits were increased, the issue was resolved.

 Symptoms K2 SmartForm / SharePoint Web Part Not WorkingWe have a custom K2 SmartForm that is used within SharePoint as a WebPart.The form has, essentially, suddenly stopped working and we cannot understand why.No errors seem to be generate because of this. Diagnoses On the meeting we found that the Smartform had the same issue as SP.We proceeded to look at the SmartObject and found that it did not execute.We increased the SmartObject timeout value and the SmartObject then completed.However the Smartform still did not complete and errors out in a workflow step.We downloaded the latest version of the process and ran through all the activity steps smartforms integration and updated the design canvas in K2 studio.We then redeployed the process. Resolution The redeployed process worked and the form in runtime and in the SP web part works.There is an issue with how long the process takes to complete but this will be investigated with in a separate ticket.  

 Symptoms Problems with e-mails delivery to end-users - e-mails delivered with delay, sometimes up to a few hours late.In the MSMQ queue a lot of objects sit for hours without being processed. What could be the reason for the accumulation of objects in the queue? Do accumulation affects e-mail delivery delays? Diagnoses Sometimes similar issues can be caused by the fact that K2 database is full, specifically the EventBus schema. As a quick check on this you can check if there are any tables in the EventBus schema that have more than 10,000 entries. This was not the case in this instance.It is possible that such problems arise after K2 user base increase which put more load on the server and requires scaling out and performance tuning. As a a solution to slow processing MSMQ messages while K2 Server is under heavy load you can also conside the following recommendations on tuning MSMQ settings:https://support.microsoft.com/en-us/kb/901279https://blogs.msdn.microsoft.com/johnbreakwell/200

 Symptoms 1) If account is disabled in AD, what values should it have in Enabled and Resolved fields of Identity table? It is not very clear what Enabled and resolved values mean.2) You may notice that number of records in Identity table with Resolved=0 and Enabled=1 if way greater that the number of active accounts in AD. Is it normal situation or there are some issues with synchronization of Identity table? Diagnoses (1) When you disable user in AD he gets Enabled = 0 and Resolved and ContainersResolved flags will be set to 1 in case they were resolved previously.When you delete user in AD he also gets Enabled = 0 and Resolved and ContainersResolved flags will be set to 1 in case they were resolved previously.As soon as identity record becomes disabled auto refresh process won't be trying to resolve disabled user anymore, but still if some process or UMUser SmO will try to use disabled user K2 will try to resolve this user again and depending on his status in add either resolving use

Is there a way in Nintex 2010 to track how many actions have been used?I can see the list of workflows on all sites in central admin -> Nintex workflow management -> Farm workflow inventory. But there is nothing that can tell how many actions per workflow have been utilized. We're on a subscription model for specific number of workflows (and with a certain limit of actions) that expires after 1 year and I would like to keep track of how much have been consumed so far.Enterprise NWF2010 -> https://community.nintex.com/docs/DOC-3838There is a way to track office 365 for consumption but not for on premise that are on subscription. https://community.nintex.com/community/build-your-own/nintex-for-office-365/blog/2016/11/14/how-to-track-your-workflows-in-o365Any help is appreciated.

Hi, we have a scenario where a very long form needs to be created. It involves attaching various documents as well, such as ID, Proof of Residence, etc. This was previously a paper form.In its paper format, the person filling it out would be able to complete portions of the form at their lesuire, and be able to return to it at a later time to complete. For example, they may fill out the form to 80%, and then realise they need some information, which they then are able to complete a day later.Is this possible with a Nintex Form? Specifically, a Nintex Live form.Our aim is to streamline and make the process easy for an online completion, and not 'force' the user to have all information on hand within a single sitting.The idea would be that a person could semi-complete a form, and be able to return to it at a later date to complete. Once complete and submitted, any workflows would then initiate.If Nintex cannot do this, has anyone found any other ways to do this?Thank you
