[rules-users] "or" not working

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.
