[ve-dev] VE in PDE

["Janak Mulani" <janak.mulani@xxxxxxxxx>]

Hi,

I have set up development environment for ULC VE plug-in.

Versions: Eclipse 3.2 and VE 1.2.

VE plug-ins have been imported as plug-in projects in the workspace.

To test if the VE plug-in is functioning ok, I launch the target workbench
using Run.

In the target workbench, I create a Java project and create a Visual class.

VE and palette come up ok.

I drop a JButton on the canvas. The generated code does not have a getter
method, only a variable is created and there is the an exception in the log
file (see below).

Could you please tell me what the problem is? Is my set up wrong or is there
a bug with VE

Thanks and
