Skip Validation Phase
Hi, All!!!
I've confused with it in JSF. I have some validation logic on my form:
2 textboxes which have required attribute
And also one drop-down ( I used immediate=true, because I don't want to run
validation before valueChangeListener ).
In my valueChangeListener I tried to ignore validation phase at all, so in
the end of this method I called
FacesContext.getCurrentInstance().renderResponse();
Here is code:
public void vendorChanged(ValueChangeEvent event) {
FacesContext context = FacesContext.getCurrentInstance();
String value = (String) event.getNewValue();
if (value != null) {
. updating bean data, I expected that data will be appear on my
page
}
context.renderResponse();
}
But when this valueChangeListener finished data isn't updates on the my
page? Why? Any ideas?
Thanks in advance,
Yura.

My first attempt to solve such a problem was to create the
OptionalValidationFramework discussed on the wiki, but I don't really
like that approach. It worked for me because I had a lot of
dropdowns on the page.
You might take a look at using the Sandbox subform validation as an
alternate way to do optional validation.
If you have only a few components that need to work like this, you
could manually perform the update model phase yourself. I haven't
tried it, but you might be able to call component.processUpdates() in
your handler.
Otherwise, you can manually grab the submitted or validated local
value from the component, and manually put it into the backing bean.

I guess I was too subtle.
You're not skipping just the validation phase. You're skipping all
phases after ApplyValues, including UpdateModel. Your backing beans
will not be updated.

I guess I was too subtle.
You're not skipping just the validation phase. You're skipping all
phases after ApplyValues, including UpdateModel. Your backing beans
will not be updated.

I know this, but for skip validation phase I'm using call:
FacesContext context = FacesContext.getCurrentInstance();
context.renderResponse();
Thanks,
Yura.

Short answer: immediate doesn't skip validation phase.
