Hi droolers! I installed the Drool Eclipse 5.4.0 Final plugin into an Indigo SR2 installation of eclipse and found I could not get the rule debugger to work. I created a standard rules runtime for my workspace. Then I created a drools project with the HelloWorld rule and the sample loader java class. I then set some break points in the consequent parts of both the "Hello World" and "Goodbye" rules. I then right-clicked on DroolTest.java->Debug As->Drool Application. However, the debugger did not pause on the break points as I expected. This was despite the fact the program gave the expected output: Hello World Goodbye cruel world If I put breakpoints in java code the debugger pauses there as expected. Any idea where I might be going wrong here? Thanks, Frank
