If WorkflowRun KAREntryHandler open method returns true, KARFile openKARContents gives an error. It looks like all entryhandler opens are returning false (why is actormetadata handler never returning true? i'm guessing this is just by mistake -- fixing this would be a good test).

java.lang.Exception: Error on Open: null

at org.kepler.gui.kar.OpenArchiveAction.openKAR(OpenArchiveAction.java:153)

I've been trying to spot the problem for quite awhile now but am failing...sorry, either tired eyes, or something difficult to find. My preference now is to just rewrite that method rather than keep trying to find the bug, so I'm filing this instead in case you (Aaron) want to keep it this way or if it's still under construction (e.g. the dependency list stuff). If you want me to try a rewrite just let me know...
