steve barfield commented on JBRULES-821:
----------------------------------------

This comment follows on from my interpretation of Michael N's original post (25/4) which as I read it would result in a rule with a single value hard coded in the condition. Michael A's post, if I understand it correctly, is asking for some of the more powerful features like 'from' to be added which provide dynamic conditions derived at time of rule execution.

This idea was prompted by the user requirement for drop down lists within JBRMS which we are proposing to provide by importing a java bean into the package. This enables a drop down list as shown in the attached document.    

Would it be possible to introduce shared code+descriptor table(s) that could be used both by JBRMS for the LHS rule conditions and the application that will be asserting objects for the rules to process. Rather than hard coding conditions in rules :

     Person( country=="IRQ" )

This would permit drop down lists using the descriptor

     Person( country==IRAQ)
                                      INDIA     
                                      POLAND

which when IRAQ was selected would generate the same rule

     Person( country=="IRQ" )


This would have 2 advantages :
  1) the same code "IRQ" would be used in all rules for Iraq
  2) the calling application would use the same table for populating country in the 
      object to be asserted ie."IRQ" thus ensuring the rule would be fired.
