NPE in EdgeLabelQuery when moving node [message #1769529] Tue, 01 August 2017 11:06 Go to next message

Hi,

If I move the node using the arrows (or the mouse) and the node is too close to the next node (and there is an edge between the nodes), an exception (see below) is displayed and the node can not be moved anymore.

Is it a Sirius error (GMF) or "feature"?

Thanks.

Martin

Hi,

It is a bug in Sirius. The stack corresponds to the bugzilla [1] in EcoreTools.
You can create a Sirius bugzilla [2] and link it to the EcoreTools bugzilla.

Regards,
