To replicate: 1) create a drift template 2) go to resource A's drift tab, create definition from that template, but detach it 3) delete the template 4) go back to the resource A's drift tab The template is no longer in existance. But the definition was detached, so it does not get deleted. However, what should it show in the "template" column of the table? It should probably be empty. But it looks like its trying to get the name of an non-existent template This actually is pretty bad because now I can't view the drift definitions anymore, not just for this definition, but I assume I can't see any defs, because it's the table that can't render - and the table lists all definitions.

git commit to master: 1c2b7c6 jay looked around and didn't find any other places where driftDef.getTemplate() is called that isn't protected from null checks so this appears to be the only place where this problem occurred.
documenting that i am reproducing the original error (I don't have the fix yet).... retest tomorrow.
Verified on master build#833 (Version: 4.3.0-SNAPSHOT Build Number: ee66d10) Created a drift template and a detached definition from that template in drift tab of resource. Deleted the template, navigated back to the resource's drift tab. Verified that there is no exception thrown and the "template" column of detached drift definition table of the resource displays 'None'.
Setting target release to be RHQ4.3, since this was tested against master.
