Re: [rules-users] what is the difference between process variable & global variables?

hi, this seems like a basic question i should know the answer to after reading some documentation but unfortunately after doing some tests with onExitActions there seems to be some discrepancy between what doc reads and how the process/action behaves. Could anyone verify my observations: 1. while documentation in "4.4. Data" reads "...Actions can access variables directly, simply by using the name of the variable as a parameter name" in fact this is INCORRECT as at that point actions expect a global object to be in the session!! e.g. below code in onExitAction throws an exception if tracker obj hasn't been defined as a global variable and entered into the session (it doesn't matter that the process has tracker variable defined) tracker.addVisitedNode("dasdf"); 2. the only way of accessing process variables is via context object as below context.getVariable("tracker") 3. inserting/updating object in the session can be done a) context.getKnowledgeRuntime().insert("myFact"); b) insert("myFact"); looks like there is no difference here and the second one is simple a shorter version of doing the same -- View this message in context: http://drools.46999.n3.nabble.com/what-is-the-difference-between-process-...
