Symptoms

K2 SmartForm / SharePoint Web Part Not Working
We 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.
