2. Configure the MultiSelectList control to populate list of values 
3. Embedded this section in OOTB CaseManager portal 
4. Launch CaseManager Portal 
5. Now drag and drop a value from the grid into another workbasket

Root Cause

Wrong Mode exception occurs for the String list property as the list definition is not looked up before making the call to remove method.


Apply HFix-25465.
This hotfix will check the lookup the property mode in the dictionary before trying to remove the property using a symbolic delete. This way, if the property mode is unknown before the delete, the mode becomes known in the lookup and there is no wrong mode exception thrown.​
