It is different from http://code.google.com/p/gwt-ext/issues/detail?id=267

What version of the product are you using? On what operating system?
I am using the get-ext 2.0.5, gwt 1.5.2, window XP. Someone points out it
only occurs at host mode. 

Please provide any additional information below.
I traced the issue to code  Form.java
 346: status = action.response.status;
If I change the code to 
       status = action.response.status === null || 
        action.response.status === undefined ? 
         status : action.response.status;
as it is for actioncomplete

The FormListener's onActionFailed is called properly.
