I am experiencing this same issue with a similar exception to the one listed above. I think I can repro this every time, the NPE happens when you open an XML resource with the "Android Resource Editor" instead of the "Android XML Resources Editor", then go to the "Resources" tab, that should get you several NPEs, then when you go back to the filename tab every charachter you type throws an NPE.
I'm not sure exactly if the "Android Resource Editor" is the default by default. I've pasted more of these exceptions at http://pastie.org/1026261 On Jun 30, 9:42 pm, Bob Kerns <[email protected]> wrote: > There are several possible editors to use to edit these files.
