This is most helpful. <blockquote cite="mid:c21e62b2-8d60-4be4-a09c-192798e31433@free.fr" type="cite"> In this Cuis image, the window at the top-left presents the Smalltalk sketch editor with the mini-debugger. The debugger presents the four local variables to the script f a b s, with the correct classes. But once you clic in one of these variables, its value is printed as nil. In the Browser at the top-right, the method handling the exception and plugging the error. There is one line comment to open the regular debugger. </blockquote> The regular debugger suspends the process being debugged, and debugs it from a separate UI process. In your code, by the time the mini debugger is opened, the sketch execution as already been terminated and pruned from the stack. So, those variables don't even exist at that point. A way to fix this is to suspend the sketch process, and debug it from outside it. Something like: executeSketch | myContext | self stopSketch. codeView scroller acceptContents. self switchToPauseButton. DrGeoSketch when: #newSmalltalkSketch send: #compiledSketch: to: self. sketchProcess := [ | t | t := DateAndTime now.

"Debugger openProcess: sketchProcess context: myContext label: 'Debugg'" sketchProcess suspend ] ]. " When we get there, sketch has been entirely executed, switch back to play button " self switchToPlayButton.

You are still far from a working debugger. For instance, in this case, the error happens in a stack frame that is not visible, so you can't point the user to it. I don't know if a debugger without a view of the stack call is of use... Maybe if you set the context to the one throwing the Error? I wonder if it would best to simply use the regular debugger. <blockquote cite="mid:c21e62b2-8d60-4be4-a09c-192798e31433@free.fr" type="cite"> ...
