When creating a new BPEL project, the workbench displays the "do you want to switch to the BPEL perspective" dialog (if enabled) as expected. Clicking "yes" apparently switches to the new perspective but the context menu->New action does not display the expected items (e.g. "BPEL Process File", "Apache ODE Deployment Descriptor", etc.) while the File->New (from main menu) does work as expected.
Also, there seem to be 2 BPEL perspectives defined, the second one is labeled <BPEL> and that one displays the correct context menu.
