I have a rule working. I that rule I have a fact which I want to change (meaning: a property on my factobject) - i tried modify, this didnt work, so I now retract and assert it anew. I checked that with eclipse-debugger-workingmemoryview. It is really removed and then changed and inserted again into the workingmemory. The rule does not get fired after that, even when I set the same properties on my factobject. Is there something that has to be done besides modify/ retract and assert? -- View this message in context: http://www.nabble.com/Rule-does-not-fire-after-modify-tf3369145.html#a937...
