SoapUI Eclipse plug-in hangs when generating code

Hi guys,

I've recently downloaded the soapUI plug-in for eclipse. I've managed to add two wsdl files to my project.

But when I right click>generate code, whichever option I choose, eclipse hangs when I press generate and I have to kill the process.

Any idea why this is happening?
I'm running eclipse 3.7 on ubuntu 11.10.

Cheers
