[news.eclipse.modeling.gmf] Re: Problems with 2.1 RC1 with gmfmap, and g

[Brian Jakubik <brian.jakubik@xxxxxxxxxxxxxx>]

I think i found the problem node/diagram label, and removed it, and it 
works now. well sorta...

on the body for the value expression, is there a setting that I need to 
set to have the body contents generated, as right now it is still 
throwing java.lang.UnsupportedOperationException(...)

thanks
