Hello,

I got a Composite Component with a class anotated with @FacesComponent that has a ActionListener, ValueChangeListener and much more.

My Problem is that in some situations I do need to add a FacesMessage and update my p:messages tag with the new message.

I Tried everything to solve this problem... but the p:messages is not rendering my messages.

Maybe because the Faces Messages is rendered only after the complete JSFLife Cycle and as far i know... JSF Listeners do not obey the normal JSF Life Cycle.

How can I add the message?

Thank's for your help.

JSF listeners do, in fact participate in the JSF lifecycle. What part of the lifecycle the listener is invoked in depends on what kind of listener it is. However, most listeners post messages by throwing Exceptions, not by attempting to attach them to the FacesContext.
