[rules-users] RE: Rules with Lookup Tables...

[Edson Tirelli]

  I'm not sure I understood what you are trying to do, but syntax is 
more like:

rule ...
when
    // getting the codes from the table
    Code( $shCode : sh_code ) from lookupDAO.getLookupValues( 
"MILT.CUSTNO" )

    // matching the objects if the code
    $gateIN : RKEM_Move( CUSTOMER_REFERENCE_NUMBER matches "^HX.*",
                                           ACTIVITY_LOCATION matches 
"^US.*",
                                           list contains $shCode )
then
   // do something
end

   There are other ways of writing this, but I would like to have your 
rule written down in english before suggesting something else... :)
