Description swpalmer 2004-07-29 14:27:13 UTC

Netbeans 4.0 wasn't selectable on the bug reporter page. But I 
was giving the daily build from July 28 a try.
I attempted to add a project to the classpath for compiling 
sources of another project and when ever I try to navigate into a 
directory with the Add Project file dialog I get this exception:

this makes it impossible to add classpath dependencies

Comment 1 Jesse Glick 2004-07-29 16:40:10 UTC

Yes, it seems that the file chooser on Macs (but not other platforms)
fires SELECTED_FILE_CHANGED_PROPERTY with selectedFile == null every
time you move directories, so this otherwise obscure case (possible on
other platforms only if you manually Ctrl-click to deselect a file)
tends to get noticed on Macs first. Easy patch.

Comment 2 swpalmer 2004-07-29 17:51:27 UTC

Sounds like the underlying issue should be reported on Apple's Bug Reporter?

Comment 3 Jesse Glick 2004-07-29 19:51:19 UTC

No, the Apple (Aqua) chooser behavior is not a bug, I think; just
different from other platforms.

BTW swpalmer: use version "promo-D" for 4.0 development builds.
