Re: [rules-users] string replace collision problem
Cautionç This is answered after only a quick look.
You must notify the engie that a change has occured by calling update(plan);
in the RHS. Not calling update will modify the object, but the engine will
not take these changes into account.

Hello,
I've problem with string replacement.
See the following example.
Input string: SF
I've written two simple rules:
The first one transforms SF to S
The second one transforms S to VOL.
The expected output after the transformation should be S, but I get VOL.
(as for example for the rules: A->Z, Z->K, input A, output will be Z and
not K).
So my question is how to avoid this problem (I suppose the problem is that
the first transformation returns substring of the input and moreover does
exist another transformation rule for it).
rule "Rule1 for parameter 1"
salience 2
when
plan : plan( parameter1 matches ".*SF.*" )
then
plan.setParameter1(plan.getParameter1().replace("SF","S"));
end
rule "Rule2 for parameter 1"
salience 1
when
plan : plan( parameter1 matches ".*S.*" )
then
plan.setParameter1(plan.getParameter1().replace("S","VOL"));
end
Thank you for your response.
Peter
