[rules-users] debugging with 3.1M1 IDE?

Are you talking about standard java breakpoints in your java code or rule 
breakpoints? Rule breakpoints should always show the working memory and 
agenda.  When using standard java breakpoints, the views only show something 
if a WorkingMemory variable has been selected in the variables view.

Did you change something in the compiler settings so that variable names are 
preserved in the class files?  The IDE should filter out those additional 
objects (as they are caused by the way it is implemented and usually not 
relevant when debugging) based on their name, but seems like the names of 
the variables have been reset to defaults.

If possible, could you send me a self-contained eclipse project (you don't 
have to include drools jar or dependencies of course) that is experiencing 
these problems and a way to reproduce them? I'll then see what I can do, 
because I can't determine the problem based on this explanation alone.
