Cannot commit file anymore

Hi there,

I've just tried to make some changes to a running demo app, but for some reason I can't commit the files anymore.

I get the following error:

An internal error occurred during: "Committing file index.html".

java.lang.NullPointerException

Few weeks ago this worked without problems, and on client side as well as on server side nothing changed (at least, I've changed nothing...)

Any ideas how to debug this?

A java.lang.NullPointerException is not very meaningfull to me

Thanks,

Ben
