[rules-users] Declared Types and Globals in different files with incremental KnowledgeAgent

Dear Drools Users, I am building a network server for drools since the existing drools-server did not meet my requirements. Since I recently found a bug and find the people here very helpful I'll try to explain another issue I encountered in the hope that it improves drools 5.6 and 6.0. I noticed that declared types and globals don't seem to be found when you access them from a rule that was written in a different file. For the declared types I hacked around this issue by preprocessing the files and placing every declared type at the top of each file that needs it. For globals this is of course not possible. An example is shown below. File1 is loaded from the moment the agent starts up, then file2 is loaded. There is a difference when the knowledgeAgent detects the two files at once or one by one. In this case the KnowledgeAgent detects one file and then a few minutes later the other file and compiles them completely separately. The idea is to keep how many rules are matched of a certain type in a global. * FILE1: global_rules_matches.drl ---------------------------------------------- package ellipsoidfacts // declare global Integer RULES_MATCHED; // initialize global rule "initRULESMATCHED" salience 999 when then RULES_MATCHED = 0; end* * FILE2: testrule.drl ---------------------------------------------- package ellipsoidfacts rule "Gesture_lefthook" when // ... any precedent rules ... then System.out.println("matched gesture: lefthook"+ RULES_MATCHED); end* In this particular case, my rule is not matched. I load these rules using a changeset xml, my knowledgeagent is set to incremental (but either doesnt work). The same happens when I declare types in FILE1 and use them in FILE2. When I write the type declaration in both files it works perfectly. Being the same package I assumed that these two scenarios should work. Am I doing something wrong or is the agent not supposed to work like this and should a package be in one file? Kind Regards, De Rooms Brecht
