Page parameters propagation DELAY

[recool.qiao_haibo.hotmail.com]

Dear All,

In my *.page.xml, I define 3 page parameters as:


   <param name="doorType" value="#{scDoorOrder.doorType}"/>
   <param name="doorId" value="#{scDoorOrder.doorId}"/>
   <param name="template" value="#{scDoorOrder.template}"/>
   <action execute="#{scDoorOrder.onLoad}"/>


and in scDoorOrder I have bijection methods:


    @Out
    public Door getCurrentDoor(){
        //fetch a door using the 'doorId' from page parameter
        return currentDoor;
    }
    @In(required=false)
    public void setCurrentDoor(Door currentDoor){
        this.currentDoor = currentDoor;
    }


I found that, those page parameters are being propagated in the order I defined in page.xml, and there is delay in between. In my getter method, I always find doorType propagated, but doorId is not. However 'doorId' value will get applied a while later.

It's true that, parameters are all applied by the time page action is called. But the bijection getter setter were called before the page action. Therefore, I got ugly exceptions.

Anyone, please help.

Try setting @Out(required=false)

Outjection will be performed after any method call, in your example, this would be setDoorType.

Thanks for ur reply.

After adding required=false, there isn't much difference. And I discovered that:

In my example,
1. setDoorType() was indeed invoked before getCurrentDoor()
2. However setDoorId() and setTemplate() were invoked after the outjection was done, which is a bit weird to me.

Is there any way to force the parameter propagation?

Outjection is performed after any method call.

[joblini]

<param name="doorType" value="#{scDoorOrder.doorType}"/>
<param name="doorId" value="#{scDoorOrder.doorId}"/>
<param name="template" value="#{scDoorOrder.template}"/>
<action execute="#{scDoorOrder.onLoad}"/>

will result in this:

setDoorType is called.
currentDoor is outjected.

setDoorId is called.
currentDoor is outjected.

setTemplate is called.
currentDoor is outjected.

onload is called
currentDoor is outjected.
