Joseph Leong commented on GERONIMO-3867:
----------------------------------------

Hi Joe,

Any ideas as to which files you'll be modifying for this piece.  I've been kind of tip toeing around the JIRA's i have open that are in the plugin installer because i didn't want to clash with your work.  Or if we work concurrently, perhaps you'd like to review my patches so it doesn't clash with your designs?

Thanks!

> When attempting to export a component as a plugin in the web console a NPE is thrown is no component is selected (actually, a NPE is thrown even if a component is selected but that is another issue, GERONIMO-3866).  We should check to validate that a component is selected in the JSP.
