The problem is that if you put it in the rendering code this will basically get invoked every 30 ms. A more practical solution is to use haltOnce. This is the same as halt, only that it is guarded by a global flag. Just make sure that you enable it from the Debug world menu.
I am not expert in Morphic, but I feel there is a bug in how exceptions in Morph are handled. Create a subclass of Morph and put a "self halt" (or "1/0") in the drawOn: method. Open the morph and it will appear in red, telling that there is an error in the render loop. Now, for some reason, when blocks are heavily, the image freeze. I tried to isolate the error (i.e., without Mondrian), but I could not figure out how to do it. Alexandre

Hi Stef, this is the same behavior as what I reported in http://code.google.com/p/pharo/issues/detail?id=1525 and http://code.google.com/p/moose-technology/issues/detail?id=237 How to reproduce is also there. On 02 Dec 2009, at 08:30, Stéphane Ducasse wrote:
Do you have a example that we can reproduce?

Regarding the problem with the number of arguments in the block. Why is it crashing the image?
The image is not crashing actually. It just hangs on forever without giving a chance to interrupt the process.
Anyway, you might want to use an approach similar to the implementation of glamourValue: in Glamour.
It could be a nice fix, but clearly not a general solution. The image hangs because of a bug in Squeak/Pharo. For some reason, the exception thrown by the virtual machine is not properly caught. This is a hard problem that will need to be fixed some days.
