The Balloon engine does not like Floats or Fractions passed into its
primitives. In my experience this is the cause of problems in most
cases.
Also it could be related to the size of the canvas, but I don't
remember if you get a primitive failure there:

Hi,
I am trying to reproduce the diagram with the FAMIX meta-model. I found the
script in MOFameView>>openOn:, but there is a problem with the rendering.
I use Pharo 10250.
I attached the error report. What am I doing wrong?
Cheers,
Doru
