    listshuttle is throwing has invalid value expression

    Prakhar Paharia Newbie

      Hi,

      On the screen there are various fields,one dropdown & one listShuttle. When i change the value in this dropdown that time i am filling the source value of list Shuttle & i am reRendering it.

      Till this point it works fine. but when i submit the form than i got the error message

      rich:listShuttle is surrounded by a4j:region

      component rich:listShuttle has invalid value expression.

      at present the value in sourceValue & targetValue are getting filled via action.attribute but i have also tried it by using VO with equals & hashcode implemented.

          Hello,

          Do you use request-scoped bean to hold value?

            Bean in not in any scope.My action class is in conversation scope. Currently source & target value of listshuttle are getting filled through the class level variables defined in action class.
            Sample code

            Action class(in Conversation scope) contains:

            List sourceReport = new ArrayList;
            List targetReport = new ArrayList;

            xhtml snippet
            <a4j:region>
            <rich:listshuttle sourceValue="action.sourceReport" targetValue="action.targetReport"......etc>
            </a4j:region>
            some other fields of xhtml mapped to VO or bean
            <h:inputText value="VO.name">
            <h:inputText value="VO.address">

              Please post full page and bean code.

                One point to note: If we click edit & than try saving same record than in this case it is working but we want to add new record than validation message for listshuttle started coming.

                Xhtml code

                  So just check with debug in your ItemConverter converter methods if the conversion results are ok.

                    I am using same ItemConverter for other listShuttles also which are part of different screen.There it is not giving any problem.

                      could you please show the method policyAction.savepolicy()

                        policyAction.savePolicy is not at all called.Before that only i get this validation message for listShuttle.

                        Eventhan if you want to have a look at that method please reply i will post that.

                            Please create runnable sample with source for us. Anyway in your case we still think that the problem is in converter. Post the sample with sources and we will check it on our side.
