If client side code changes we can refresh the page to recompile it and see the results. It worked nice with GWT 2.4
As of GWT 2.5 there is a problem. Upon page refreshing a com.google.gwt.user.client.rpc.SerializationException is thrown.
If I restart the web application and refresh the page everything goes fine. So it seems to be some bug in GWT.
A few details:
- This exception is thrown if anything is changed, for example css file (!)
- This exception is thrown often but not always, sometimes it is OK.
- Actual exception may concern almost any class. In this example it is java.lang.Integer.
