Hi Mantis, The usecase iam trying to address is ,the customer has a list of parameters which i handled through the Enumeration, But for the selected parameters he needs to map a Value. The value list for a particular parameter can also be rendered through a enumeration by checking the parametery key selection in the earlier dropdown . But there will be cases where he will want to map the parameter with a value that is not there in the value list drop down . So when he chooses "Not in list" option from the value list dropdown i wanted to display a text box so that user can enter the value. Hope i debriefed the usecase Do provide me pointers to make changes to the guvnor codebase if you feel this can be handled Regards Swaroop -- View this message in context: http://drools.46999.n3.nabble.com/Guvnor-Capabilities-tp4024629p4024632.html Sent from the Drools: User forum mailing list archive at Nabble.com.
