Local fix

• Validate the double-click handling configuration in wc-server
  and ensure the inclusion or exclusion list only contain commands
   for which double-click is required.
   This will reduce the chances of running into the exception.
  
   Configuring double-click handling
   http://pic.dhe.ibm.com/infocenter/wchelp/v7r0m0/topic/com.ibm.c
  ommerce.developer.doc/tasks/tsddblclickconfig.htm
  
   Enabling com.ibm.websphere.commerce.WC_THREAD trace will show
  the commands being handled by double-click. After enabling
  tracing look for these lines:
   WC_THREAD     3 DDThreadContext setCommandName
