component reRendered before action execution

[jmchiaradia]

Hello, I have the following problem:

I have an a4j:commandButton with an action an a reRender:

<a4j:commandButton
     action="#{bean.doAction()}"
     oncomplete="Richfaces.showModalPanel('ControlLFMP')"
     reRender="EditControlLFUC"
     value="Edit Control" />

As I understand this, the EditControlLFUC component should be reRendered after the doAction is executed.
My problem is that the component is been reRendered before the doAction is executed and because of this the values of the EditControlLFCU component are not correct.

Could anyone help me?

Regards,
Chiara

You might need to post a bit more of your code as the problem you are describing is very unusual. The lifecycle dictates that the application invoke stage happens before the render phase and from the little reading I've done what is happening to you just shouldn't happen.

What makes you sure that the rerender is happening before the action? Have you put a breakpoint in your action method and checked this? What type of component is EditControlLFUC

Does your action method do any fancy async stuff or anything like that? Are you using an ajax queue? Are there other ajax calls that could be interfering with this one?

JSF has 6 phases:
   1. Restore view
   2. Apply request values
   3. Process validations
   4. Update model values
   5. Invoke application
   6. Render response

your bean.doAction() will be invoked during Invoke application phase.
your EditControlLFUC will be reRendered in Render response phase.

However, original value of EditControlLFUC will also be called during Restore view phase to rebuild components tree.

My a4j:commandButton was inside a panelMenuItem and to resolve the issue I disabled it:

<rich:panelMenuItem disabled="true">

     <a4j:commandButton
     action="#{bean.doAction()}"
     oncomplete="Richfaces.showModalPanel('ControlLFMP')"
     reRender="EditControlLFUC"
     value="Edit Control" />

</rich:panelMenuItem>

some issues are a result of nested form tags and controls outside the form
