I have the following code to set a Calendar object at Jan-1-2013 and roll it 3 days to 1-4-2013 and test to see if it is less then the current date. This in all done inside the THEN part of a DRL rule then Calendar c = Calendar.getInstance(); c.set(2013, 1, 1); c.roll(3, true); if (c.getTime().before(new Date())) { System.out.println("successfully rolled 3 days ahead"); } How to you do this in the WHEN part of a DRL rule? -- View this message in context: http://drools.46999.n3.nabble.com/Can-When-part-of-DRL-contains-simple-lo...

that is exactly what I did but I need to call eval(myFunction) and it will be slow since eval() is slow. So there seems to be no way to do "logic" when I am in the When part right? thx!!! -- View this message in context: http://drools.46999.n3.nabble.com/Can-When-part-of-DRL-contains-simple-lo...
