Unexpected results in GDST when using enumerations with commas

XMLWordPrintable

    • NEW
    • NEW

      When using enumerations where the values itself contain a comma, the rules generated by a GDST are unexpected, as the "contains in" operator splits those values in the enumerations. Example enumeration:

         fact: person
   field: city
   context: ['paris','london','new york,boston']

      Note: see the 'new york, boston' sample.

      The code generated will be:

      rule "Row 1 personGDT"
    dialect "mvel"
    when
        p : person( city in ( "new york", "boston" ) )
    then
end

      Basically "paris" and "new york,boston" will be treated by the DSL parser as 3 strings in the DRL generation and will produce someting simiular to
      p : person( city in ( "paris", "new york", "boston" ) )
      But what the customer expects is the following
      p : person( city in ( "paris", "new york,boston" ) )
