RE: [ve-dev] Adding JButton from canvas to JFrame

Hi,

It happens when running VE in target platform in plugin development
environment.

In fact dropping a component directly into frame also does not work.

There is an exception:

!ENTRY org.eclipse.ui 4 0 2006-11-15 17:34:44.843
!MESSAGE The feature 'constraint' is not a valid changeable feature
