Brendan Healey commented on RF-12063:
-------------------------------------
Clicking into and out of the input should cause the value change listener to fire,
however no message appears on the screen. Simply adding a commandButton, and copying
the message generation code from the value change listener into an action= method
and clicking the button will cause a notifyMessage to appear on screen.

rich:notifyMessages not displaying error from valueChangeListener
-----------------------------------------------------------------
Key: RF-12063
URL: https://issues.jboss.org/browse/RF-12063
Project: RichFaces
Issue Type: Feature Request
Security Level: Public(Everyone can see)
Components: component-output
Affects Versions: 4.2.0.Final
Environment: Mojarra 2.1.7, RF 4.2.0.Final, Windows 7, Glassfish 3.1.2, Chrome
browser.
Reporter: Brendan Healey
Labels: waiting_on_user
I have a global notifyMessages in a template <rich:notifyMessages
stayTime="3500"/>.
I log a global error in the usual way from a value change listener (process validations
phase):
FacesMessage message = getFacesMessage(errKey);
message.setSeverity(FacesMessage.SEVERITY_ERROR);
FacesContext.getCurrentInstance().addMessage(null, message);
but the error never appears. If I have an h:messages on the page which is ajax
rendered the message appears ok.
Regards,
Brendan.
