Environment

Component : UIM OPERATOR CONSOLE - MCS UI

Resolution

1. Deactivate all OC wasp probes (on all OC nodes). 

2. Redeploy the following package on all OC robots: 

mcsuiapp_portlet-1.3.9-HF6.zip

3. Activate all OC wasp probes (on all OC nodes).

4. Clear browser cache from ALL time and retest the scenario. 

Note: If this issue impacts an earlier or later version, redeploy the correct mcsuiapp_portlet package for product release.
