eclipse.buildId=I20110510-1040

With this build when I try and use Command-C to copy, I get the following error. The copy does seem to work ok. Using the Copy entry from the context menu works as well and does not produce the error.

Not sure if it is related but I'm also seeing this when I try and do a Command-V to paste.

Hi Kat, what were you doing when it generated this log?  Using the context menu, or tool item?

EGit, can you point us to the definition for the command and handler (and possibly keybinding) for comment #5 ?

This is the problem.  The command has a default handler, which means that handler is active all of the time.


For the AIOOBE
ava.lang.IndexOutOfBoundsException: Index: 0
	at java.util.Collections$EmptyList.get(Collections.java:3212)
	at org.eclipse.egit.ui.internal.repository.tree.command.CopyPathCommand.execute(CopyPathCommand.java:28)


Line 28 does a getSelectedNodes(event).get(0); which fails on the empty list.

For the CCE:
java.lang.ClassCastException: org.eclipse.jdt.internal.core.JavaProject cannot be cast to org.eclipse.egit.ui.internal.repository.tree.RepositoryTreeNode
	at org.eclipse.egit.ui.internal.repository.tree.command.CopyPathCommand.execute(CopyPathCommand.java:28)

RepositoryTreeNode node = getSelectedNodes(event).get(0);

getSelectedNodes(*) just does a structuredSelection.toList(), so if you have a selection in the package explorer, you'll get a CCE.

Possible options to fix it:

1) move the handlers into o.e.ui.handlers EP and make the handler active when the selection is valid.

2)  move the handlers into o.e.ui.handlers EP and make the handler enabled when the selection is valid

To do either 1 or 2, you can take the visibleWhen definition contents and move it into org.eclipse.core.expressions.definitions so it can be re-used.

3) try the checks in the setEnabled(*) call.

4) just protect the execute, either in the execute, getSelectedNodes, or both so that you get empty lists when the selection type isn't correct.
