nullPointerException on mouse click

[pieren]

Today, I saw a nullPointer exception when creating new data (many new adjacent buildings, so new ways/nodes overlapping). Here is the bug report:

Since I was not able to restore an operiting editor, I lost my unsaved edits. That's why I will classify it as 'critical' (I think it will be very hard to reproduce).

My version built and running on Eclipse:
Build-Date: 2010-04-08 18:47:04
Revision: 3174
Is-Local-Build: true

Is this reproducable?

Is this reproducable?

This is already said in the original description. Since I didn't see it again, I will close it. The report was more for traceability and if someone else is seeing the same problem.

Sad that there is no ticket status 'unreproducible'.

Now there is.
