I am unable to reproduce this problem.

Can you provide some additional information on your project setup?

Thanks for the additional info.

Comment 9 Chris Jaun 2010-08-11 13:23:45 EDT

I cannot reproduce this problem in wtp 3.2.1 with the included files and project.

Comment 10 Steve Gevers 2010-10-25 17:11:20 EDT

Seems to be happening to me as well.  I haven't figured out what file is causing the problem, but I just downloaded the current version of dojo.  I get the same error with the stack trace ending up on the same line of the same class.  I noticed the version of the JDK was the same, so I upgraded that with no change.  The difference I have is I can't disable the Javascript facet, so I just keep getting the error.

The file which causes the problems.

The Problem is not a Problem of Eclipse itself, as it seems.

Ran into the same problem and did some research. If you use the current Dojo Version (1.5, and maybe some of the versions before) there is a resource file which seems to cause the error.

Please check for the "dojox/gfx/resources/svg2gfx.xsl" file. Deleting this file (or making the xsl valid) solves the problem.

I attached the file for testing purposes if anyone is interested in.

Kind Regards

Jan Peters

Comment 12 Steve Gevers 2010-10-26 10:04:46 EDT

Thanks for the work around.  I had seen that there was an error in the file, but didn't associate the error with the NPE.  I don't know if the XSL is really valid or not, but even if it isn't, an NPE isn't really an acceptable reaction.
