-------------------------------

             Summary: Wrong variable substitution when using date regex in dsl [when] construct
                 Key: DROOLS-423
                 URL: https://issues.jboss.org/browse/DROOLS-423
             Project: Drools
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
    Affects Versions: 6.0.1.Final
         Environment: windows 7
            Reporter: jan klok
            Assignee: Mark Proctor
            Priority: Critical


I have created an dsl with (among others) contains the following substitution rules;
[when][]{day:((0)?[1-9]|[12][0-9]|3[01])}[-/ ]{month:((0)?[1-9]|1[012])}[-/ ]{year:(19|20)\d\d}=%{day}/{month}/{year}%


when the following dslr rule is transformed using this dsl  : 

rule "validation_4"
 no-loop true
    dialect "mvel"
when
  Als bij een "vrijstellingsaanvraag" dossier de
     - gebDat is 25-08-1990 
 then
  Log "Validation_4 Ok : gebDat is 25-08-1990"
end

the date 25-08-1990 is transformed to %25/25/null%.

This is the complete dsl :
