delete a message from FacesContext messages list

[Alin Dosoniu <ad...@hotmail.com>]

Hello,

Is there a possibility to access the list of messages from FacesContext and to remove an item from it? I had a look at the sources and did not see one.

I have a page with an inputText control and it has a validator. The scenario that I wish to implement is like this:
- user goes on the page, introduce a value in inputText control and press Ok.
- on the server the validator method checks the value and it is not ok, so return the user the same page with the error message displayed. Until now, everything is ok.
- I want to offer the user the possibility to remain on the same page but to not display the message. Suppose there is a button on the same page that goes the user to the same page but with another state of the page (before it was New, now it is Search). For this, I will need a method to remove the error messages added by validator(s).

I tried to call FacesContext.release() (which sets the _messages on null), but run in a NullPointerException in LifecycleImpl.render method.

Is there another way to achieve the same behaviour?

Thanks in advance,
Alin.

Yes, it works! I forgot about immediate :( ..

Thank you,
Alin.


I don't know if I understand you correctly. But, could be useful to
you to use the 'immediate' attribute in your button?
