I am working on GWT-Ext 2.0.4 .
I have just changed panel class and compiled it and it din't threw any error.
But when i ran the application in Hosted mode i got the following error

[WARN] Exception thrown into JavaScript
java.lang.Error: Unresolved compilation problem: The constructor GrdRowListener() is undefined


GrdRowListener compiled successfully and there were no compilation errors in the whole project . Also i cleaned the project and build it again but no luck.

Strangely this code works in WEB-MODE and not in hosted mode.

Appreciate your help if you have come across this situation.

There are differences between the hosted mode and the web mode. Basically, in hosted mode the actual Java-Code is executed, in web mode only the compiled Javascript-Code is executed. Here's an explanation.

Now for the (possible) cause of your problem: Does your GrdRowListener contain the empty constructor? If not - does it contain any non-empty constructors, so that the default (empty) constructor is not available? An empty constructur is sometimes needed for object initializations, e.g. deserialization / bean creation. Pure Javascript should work fine without such a constructor, but Java code won't and that might be the root of your problem. Add the empty constructor to your class and test if it works.
