Unable to create editor ID com.google.gwt.eclipse.core.editors.gwtJavaEditor: The file does not exist.

[Shiva]

Hi,

I am working on GWT project. I have eclipse galileo 3.5 and GWT SDK
2.0.2. When i upgraded my workspace with GWT plugin everything worked
fine.

Its strange but today when i have restarted eclipse, none of the
projects in my workspace were visible in Package explorer.

But when i tried to open any java file from recently opened menu,
it throws the following expection on the console:

Message: Unable to create editor ID
com.google.gwt.eclipse.core.editors.gwtJavaEditor: The file does not
exist.

Exception Stack Trace: org.eclipse.core.runtime.CoreException: The
file does not exist.
