Drag and drop from Palette into a compartment issue [message #1105943]

Hi, I have a node with a compartment. When I drag a node from the palette into the compartment, nothing happens and I see a NullPointerException in the logs. However, after trying for 3 or 4 times and holding the pointer in the same position for a few seconds, it works fine. Is this an initialization problem? I am not sure what is going on. Since it works well after a while, this is not a fatal error but an annoying one. I would like to know what needs to be initialized for this to work the first time.
This is the method:
java.lang.NullPointerException at org.eclipse.gef.dnd.TemplateTransferDropTargetListener.updateTargetRequest(TemplateTransferDropTargetListener.java:138)

Any suggestions towards a solution is appreciated.

Thanks

I figured out why this is happening. The focus must be on the compartment to drag and drop from the palette. Clicking twice on the compartment brings it into focus and drag and drop works fine. Smile
