When attempting to open an HTML file in a Web Project using the MyEclipse Visual HTML Designer (the default editor after a clean install of MyEclipse 5.0M2 on top of a clean install of Eclipse SDK 3.2) I get a NullPointerException.

I’ve found similar posts in the forums but they all deal with Linux. I am running Windows XP SP2. I have Internet Explorer 6 (with the latest patches) and Mozilla Firefox 1.5.0.4 (which I use by default).

Here’s what appears in the Error log:

Any help is appreciated. I am a professional subscriber. Let me know if I can provide any additional information that will help.

Thanks!

Please restart using the -clean command line argument, that should fix you up.

That did the trick. Thanks!
