NullReferenceException when pressing ESC while dragging (#398)

(Bug Reports)

Hi,

we evaluate Software Ideas Modeler for our company.

I will submit bug reports for problems we encounter.

Some parts of the error messages are in German (I think because of .NET on a German Windows machine).

BUG: NullReferenceException when pressing ESC while dragging

Steps to reproduce:

1) Drag a shape (for example Start symbol of a flow chart)

2) Press ESC key on the keyboard while dragging (while holding the left mouse key down)

3) Release mouse key

System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.

Hi, I have a question concerning this bug:

I often use the ESC key in other programs to abort the current mouse operation (dragging, resizing etc.). Because of that I stumbled upon this bug. Is the ESC key used in SIM for abort?

Hi, currently ESC for cancelling an action is not implemented, but it will change in the next release.

Adding this functionality will be a great addition.

Thank you for the fast response.

I really am impressed with SIM so far, keep up the good work!
