[rules-users] DSL syntax and mapping

I have the following coded in my .dsl: [condition][]- with a medical code of "{medcode}"=medcode == "{medcode}" In the BRMS gui, I write my rule as: - with a medical code of 1045 It gets mapped/converted in the .drl as: medcode == " 1045 " Why is it adding a space at the beginning and end of the code? Is something in the way I have it coded causing it to do that? It should be, and I expected it to be, medcode == "1045". Also another, separate, question - when I use the BRMS point-and-click gui to create my rule from the model, it generates the rule and inserts 'Dialect "MVEL"' prior to the "When". Why and what is causing it to be inserted? Is it needed? Is that just the default? Just wondering. Thanks, Rod
