>             Project: JBoss Seam
>          Issue Type: Bug
>            Reporter: Christian Bauer
>            Priority: Minor

> Tough one... before I isolate the problem to a standalone test, these are the symptoms:
> A page has two <h:datatable> components, let's say tableA and tableB. There is a <h:form> around tableB with a <h:commandButton>. When this button is pressed, I execute an action method on a conversational component and update some data in the current conversation that is shown by tableA. The page is rendered again and tableA shows the updated data.
> However, if in the action method I use
>         FacesMessages.instance().add("Updated object");
> (or any other variation of FacesMessages), tableA is not re-rendered but shown with old state. If I click the commandButton again, tableA is rendered fine (!).
> Now, if I replace the call to FacesMessages with this
>         FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("Updated Object"));
> all works as expected and on every RenderResponse of the page, tableA is rerendered. 
> I verified that the tableA datacomponent is not rendered again. Interestingly, the backing bean data for tableA is called during RenderResponse every time, it just displays the same old component (which, I think, it remembers somehow from the RestoreView phase).
