Description Martin Olsson

I didn't even know that there was an undo feature inside the GUI editor, but 
today I accidently pressed CTRL-Z instead of CTRL-S and the undo started... and 
crashed.

Try adding some extension in the extensions page and then press CTRL-Z.

This is actually two bugs imho;

1. The details is very very poor so I really don't know what happened. A 
stacktrace would be great for debugging.

2. The undo obviously does not work correctly.


here is a screenshot of the crash:

I don't have time for extensive reprod testing atm, maybe someone else can 
assist with this and see if they can get the plugin.xml editor to crash using 
weird combinations of editing and CTRL-Z undoing.

FWIW; the GUI editor also added this weird attribute to my actionSet tag. The 
attribute said:

sibling_order="org.eclipse.pde.internal.ui.model.plugin.PluginElementNode@df3384
"

...and it seems like this is an invalid attribute (its listed as such in the 
problems tab anyway?)

Hi Martin, is there any way you might be able to attach a stack trace from the NullPointerException?

generally speaking, Undo does not work in the manifest editor.

Symptoms may vary.
