PRPC freezes during 'FinishAssignment' activity call in the flow



Occasionally, PRPC freezes while completing an assignment in a flow. A custom button is used to navigate from one assignment (screen) to another in the flow. When F5 is used to refresh the screen, the flow continues successfully.

Steps to Reproduce

This is a sporadic behavior and there is no specific use case to replicate it.

Root Cause

A defect or configuration issue in the operating environment.  Analysis of the issue indicates that it is probably a bug in IE8.  Fiddler traces display a normal response is returned to the Browser and the Browser reacts to it in such a way that no error is generated; the Browser acts as if the response has not come back. The last action performed was a Form Submit, which is basically a Browser-managed interaction.

The fact that PRPC is running as an embedded iFrame within another application is probably one of the tipping factors that generates this intermittent problem.


IE8 is known to have a number of problems.  Upgrade to IE11.
