Description of problem:
Seems dashboard name max length supported on Database is 200 chars. There is no restriction on client side (GUI). If we enter more than 200 chars throws exception on server backed and error message on GUI, but it is not much relevant for this error. GWT shows new name until navigate to another menu!

Version-Release number of selected component (if applicable):
Version: 4.1.0-SNAPSHOT
Build Number: a98c893
GWT Version: 2.0.4
SmartGWT Version: 2.4

Browser: Firefox 3.6.18
OS: RHEL 6.1 X86_64

How reproducible:
100%

Steps to Reproduce:
1.Navigate to dashboard
2.Select a dashboard and go to edit mode
3.Change the name, new name length should be more than 200 chars
4.Click on 'View mode'
5.Throws exception on back-end (valid), but new name is showing on dashboard until navigate to some other menu.  
  
Actual results:
Throws exception on backend and exception message on GUI (not much user friendly), GWT holds new name until navigate to another menu.

Expected results:
Should be validated on client side itself, do not load server with huge error trace. On GUI side message should be more specific for this error and old name should be retained on GWT.
