Find label of component
Hi.
How can I get the label (outputLabel) for a specific component? I need
this, to add the label text to a custom validation message. It seems
that {0} isn't filled automatically with the label when I add a custom
message with addMessage to the clientId (field).
regards,
Veit

Yes, ok you're right - sorry.
I didn't know, that you have to specify two different IDs:
--cut here--
FacesMessage lFM = getFacesMessage(FacesMessage.SEVERITY_ERROR, pMsgKey,
new Object[] {lShortFieldId});
getFacesContext().addMessage(pFieldId, lFM);
--cut here--
Where pShortFieldId is e.g. password
whereas pFieldId is registration:password.
Now, it works. Thanks.
regards,
Veit

Right, I understood you meant customized (programmically created)
calls to addMessage.
But that's the same thing that the validators do internally -- call addMessage.
So if standard validation is working, perhaps the problem is that
you've specified the wrong clientid value? (I find it easiest to bind
the input to the backing bean and call input.getClientId(facesContext)
to fetch the client id.
Either that, or maybe your labels aren't set up properlly?
This should be one of those "just works" situations.
The code for printing out the label is handled in the t:message(s)
component and should be independent of the message generation.

Hi.
No, I mean no std. Validation Error messages. These work fine.
I mean custom Messages that you add with
FacesContext.addMessage(ClientId, FacesMessage). This will be printed
"as-is" with no field label attached to it (as {0} or similar).
I've used some workaround that is used internally by myfaces. Iterate
over all UIComponents on the page, find the OutputLabels, look at the
"for" Attribute and get its Component. If it's the label of the given
field, extract the label value - which is not very nice. All you get is
the EL expression - you have to parse and I18N it by yourself :(.
But works for me.
regards,
Veit

If you've set everything else up, it should be automatic:
