Problem with a stencil that I developed

[nilani]

Hi,

Please see the attachment with a stencil that I developed using BPMN basic shapes and I have included a new gateway type for it. Get a blank page and drag and drop the gateway shape. And when you check the shape data window at point of dragging and dropping it shows nothing. When you click again shape data is shown and you can see in the right click menu gateway type is shown.

Why does this happen? I want see the right click menu for changing gateway type at the moment user drag and drop it in to the page 
Please heelp me???
Thank you.
Regards,
Nilani.
