one day we should all sit with igor because he is always developing everything with a
single image and
even when he get a red rectangle he can continue nicely to work on graphical and other
stuff.

Hi Veronica,
Debugging visualization is a bit tricky, mainly because of a heretic behavior of Morphic.
Your image did not freeze so you should be happy :-)
The best way to debug a visualization, is to render the visualization in a bitmap,
instead of having it on screen. For example, if your visualization is:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
| view |
view := MOViewRenderer new.
view shape rectangle width: [ :e | 100 / e ].
view nodes: (0 to: 20).
view open
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
then replace the last #open with:
view root applyLayout.
view getRenderedForm
So, the debuggable script should be:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
| view |
view := MOViewRenderer new.
view shape rectangle width: [ :e | 100 / e ].
view nodes: (0 to: 20).
view root applyLayout.
view getRenderedForm
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
If your visualization is buggy, then you will get a debugger. If nothing appears, it
means there is no bug.
The same trick has to be used for Roassal generated visualization.
Let me know how it goes.
Cheers,
Alexandre

Hi Alex,
I have already planned to migrate my tools to use Roassal...
But for now I have to use what we have with Mondrian because we are preparing an
evaluation on our tool in Pharo1.4.
I suddenly have a problem that I do not know to detect
I draw a map with dominanceTreeLayout or forcedBaseLayout.
When the layout is dominanceTreeLayout I am getting the red rectangle with the cross.
Sometimes i get it immediately or sometimes I see part of the visualization and when i
move the scrollbars the red rectangle appears.
How can I debug that?, I haven't changed my code and I have no idea what is failing
now
if I open the same visualization with forcedBaseLayout it works fine.
Regards,
Veronica
