Debugging and the execution path

[graham samuel]

Folks, for years I've been debugging Rev projects with what I now  
realise is a rather poor subset of the available facilities:  
basically I have set breakpoints, stepped through code using the  
debugger, and looked at variables using the Variable Watcher.

Now however I have a tricky 'how did I get here?' type of question  
which involves me wanting to know the caller of a particular handler,  
and the caller of the caller etc. I think this may perhaps be  
accomplished by using the undocumented executionContexts which has  
been written about recently. So far, I've noticed that at the top of  
the Variable Watcher window there is a dropdown list which may be a  
form of this: it gives the names of the objects in which scripts  
leading to the breakpoint were executed, and a line number in each.  
It doesn't contain the names of any handlers, and AFAIK I can't  
display line numbers in scripts, so this is of limited use in a  
really large script. In the RR docs the description of the variable  
watcher is not long, to say the least, and I don't think there's a  
tutorial about it either.

Can anyone point me at a more in-depth description of the debugging  
facilities of Rev?

TIA

Graham
