Dynamic Task Flow with Parameters

Ghazi Hakim

Hello,

I have a dynamic task flow in my page and I used this code and it's working :

jsff :

<af:region value="#{bindings.dynamicTF.regionModel}" id="r1"/>

pageDef :

<taskFlow id="dynamicTF" taskFlowId="#{pageFlowScope.myBean.dynamicTaskFlowId}" activation="deferred"

              xmlns="http://xmlns.oracle.com/adf/controller/binding"/>

Bean :

    public TaskFlowId getDynamicTaskFlowId() {

            ControllerContext context = ControllerContext.getInstance();

            ViewPortContext currentRootViewPort = context.getCurrentRootViewPort();

            Exception exceptionData = currentRootViewPort.getExceptionData();

         

            if (currentRootViewPort.isExceptionPresent()) {

                exceptionData.printStackTrace();

                currentRootViewPort.clearException();

               

                FacesContext facesContext = FacesContext.getCurrentInstance();

                facesContext.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, exceptionData.getMessage(), null));

               

                return TaskFlowId.parse(taskFlowId);

            }

           

            return TaskFlowId.parse(taskFlowId);

        }

The problem is when the task flow needs parameters, I need to pass those parameters programmatically, how can I do that ?

Thank you.

Which jdev version do you use?

Can't you change the parameters via their task flow parameter binding?

Or find the parameters through the metadata service of the task flow? -> http://java.sys-con.com/node/1606250

I am using jdev 11.1.1.7.0

I didin't understand the other 2 questions and the Utils Class in the link looks useful but it's using internal classes and deprecated methods.

I found this https://community.oracle.com/thread/2272511 ,he's using parameter map in the pageDef and I think that's the solution.

Thank you.
