Hi guys,
It seems to me that exceptions are masked in Mondrian. Is there a setting somewhere for turning this off?
For development, the debugger is better than the transcript ;)
Cheers, M.

More or less, but use at your own risk, because exception in Mondrian have been known to freeze the image or raise a huge amount of pop-up (due to being in the UI thread)
I think there are three places where to start when dealing with exceptions in Mondrian:
MOGraphElement>>handleException: (calls haltOnce) MOBoundedShape>>display:on: (this is the one which gives a red shape in case of error) MOCanvas>>raiseError:
Maybe Alex can provide better guidance at which does what.

It has no sender. I recently remove all sender of it since the visualization is first rendered in a non displayed form. A debugger will popup on error
MOBoundedShape>>display:on: (this is the one which gives a red shape in case of error)
This is not necessary anymore. The last version of Mondrian removed this particular case.
MOCanvas>>raiseError:
This is also cleaned.
Mircea, what do you want to achieve?

Hi Simon, Hi Alex!
Thanks for the prompt answers.
Alex, I was generating a graph in which I wanted the edges to have a width computed based on some property. The block that I passed to width: was slow and was throwing an exception. Since it was slow, the image would freeze while computing all the widths of all the edges in the view, and since the exceptions were not thrown I was waiting ...
Now the problem is fixed. I will update to the latest version of Mondrian nevertheless and see how it behaves.
Cheers, M.

Yes, this was the behavior in previous versions of Mondrian

You should not get this problem anymore.

Hi Mircea!
I recently changed the way error are handled in Mondrian. Have you tried with the last version?
Cheers, Alexandre

I would love to have a simple example of the problem with exception in UI because when an exception is raised in an image we get a debugger so I'm really curious to know why it was really a problem in mondrian. May be there is something fundamental to fix in pharo. On Aug 13, 2010, at 11:48 PM, Alexandre Bergel wrote:

Before, the script will hang the image: view shape rectangle fillColor: [:value | self halt]. view nodes: (1 to: 5)
The reason was that at each refresh of the screen, the color has to be computed which raises a debugger.
May be there is something fundamental to fix in pharo.
The error handling in Morph is scary. Time to time, the image just hang.

yes but if you want a chance to get it fixed I need a simple scenario.

I tried to reproduce one, but this is not easy. This problem has been around since I know Squeak. I will try to produce a scenario soon.
