[ jEdit-devel ] NPE from ProjectViewer when trying to remove a project

[Shlomy R. <sre...@gm...>]

Hi,

Whenever I try to remove the "active project" by right clicking the name and
selecting "Remove project", I get the exception shown below. The project is
not removed and remains the active project, and the project tree stops
responding to project selections in the project combo-box - i.e. I cannot
switch to another project.
Can someone help? I am on Windows XP, using Sun-Java 1.6.0_21, with trunk
version (from git) of PV and trunk version of jEdit.

Please note that this started to happen 1-2 weeks ago, previously I had no
problem removing projects.

Thanks,
Shlomy
