Hi,

Is there a way to hide or remove the dwr engine exception messages such as  
name: ‘java.lang.SecurityException’, message: ‘Invalid Call Count’?

This happens when i tried to intercept and amend the following parameters.  
• callCount  
• nextReverseAjaxIndex  
• c0-scriptName  
• c0-methodName  
• c0-id  
• batchId  
• instanceId

Thanks a lot.
