AW: remove FacesMessage(s) safely

[Matthias Kahlau]

Hi!

 

Did you find a solution? I also need to remove FacesMessage(s) from the FacesContext, because of removing global duplicates.

Betreff: remove FacesMessage(s) safely

I know I am doing hacks because MyFaces does not display beautiful messages in my case.

 

In a phase listener (after Model Update), I tried to remove FacesMessage(s) with generated ID like "_idJsp123"

 

    FacesContext context = event.getFacesContext();
    Iterator<FacesMessage> itr = context.getMessages();
    while (itr.hasNext()) {
      FacesMessage message = itr.next();
      if (message.getDetail().indexOf("_id") >=0 ) 
        itr.remove();
    }

 

Removing was successful without error. But during Render Phase, an error showed up.  It seems that the referenced FacesMessage is not found. I do not understand how it happens. If a FacesMessage is deleted from a collection, and it is still ref erenced by others, it will not be gabage collected.

 

Is there a way to remove FacesMessages safely?  Thanks!
