Subject: AW: Problems with ValueChangeListener and FacesMessages

Thread-Topic: Problems with ValueChangeListener and FacesMessages
Thread-Index: AcX5gj+2c+eFk4OWS5KgVRvKtDy+xwAB0ySQ
From: <andreas.mitter@magnasteyr.com>

I have one component on my page, where the immediate Attribute is set to =
true. And for this component the message is shown when the =
ValueChangeListener from my Selectbox is executed. For others no message =
is shown!
The Problem is, that I need this immediate Attribute to set to true, =
because on this component (it's a InputTextBox) I also have a =
ValueChangeListener.

So is there a way to skip the validation for this one component (for the =
InputTextBox) during the first ValueChangeListener method?

Regards,
Andy

It's only executed for the components which have immediate set to true
- if you call facesContext.renderResponse in your valueChangeListener,
it won't be executed for the others.

Martin
