You must escape ( ... [condition][]\(=(
But I'm not sure it will work, because expansion is doing nothing... I mean, text before and after expansion is the same and the system was designed to check for changes... Do you need to have ( alone in a line? Can't you use a more textual representation for "( or"? Like: rule XYX when Either Condition_1 Condition_2 End_Either then Action_1 end So you can map Either to "( or" and End_either or whatever word you chose to ")"? Just trying to find alternate ways.
