Root Cause

A missing  parameter is causing the issue while reloading and showing the harness.

In the following step of Show-Harness activity , the below java line gets the value of streamname from purpose:
   keys.putString("pyStreamName", StringUtils.crossScriptingFilter(tools.getParamValue("Purpose")));      
This purpose parameter is in turn is coming from the parameterized call to show-harness.
Purpose is set Save And Continue stage via parameter. HarnessPurpose parmeter is not set in user's parameter page. It is non-existent and hence the issue.


Explicilty pass the purpose parameter to the activtiy and that resolves the issue.
