Hi!

I've just built the trunk version of GWT and I've tried OOPHM reading
this HOWTO: http://code.google.com/p/google-web-toolkit/wiki/UsingOOPHM

The project is the unmodified sample project which is created with
Google Plugin for Eclipse. When I run it in the browser using OOPHM
and I click "Send" button in the "Web Application Starter Project", it
opens the popup with "Remote Procedure Call - Failure".

The console says:
2009.06.20. 9:37:31
com.google.appengine.tools.development.ApiProxyLocalImpl log
SEVERE: [1245483451037000] javax.servlet.ServletContext log: Exception
