a4j:commandlink and ModalPanel

[user080701]

Hi,

How to prevent to show the ModalPanel if the validation failure?

I have an a4j:commandlink and show the successful message on modalpanel by oncomplete function.

However, when the validation failure, the panel also show.

it seems even simplier to me to update the modal panel after each request but instead of calling the panel manually define something like showWhenRendered="#{not facesContext.maximumSeverity==null}". So the panel will render itself as opened if there are some messages in context.
