I saw a suggestion at the forum for a “Extensions Wanted” website. I decided to try using the forum itself as such a website.
Can anyone improve the Run-time Problem information via writing an extension that exposes the callstack?
The VM’s callstack isn’t directly accessible, so it can’t be traced in this way.
You could display the stack of invoked rulebooks (rulechange_stack). But I’m not sure it has enough information to do what you want.
