Hello,

I am trying to integrate the Eclipse MarketPlace into my RCP program. I have added the "org.eclipse.epp.mpc.ui" dependency and copied org.eclipse.epp.mpc.*.jar into the Plugins folder. As the result I can launch the MarketPlace Wizard via the Help menu. But every time I got an "Unexpected Exception" when the Search/Recent/Popular tab opened.

Could anyone give me some advises to get the MarketPlace work with my RCP?
