I'm really not sure that I grasp your need but
given that you declare the component in the template
@Component(id="myAttLabel")
private AttLabel myAttLabel;
public void onValidate(){
if(...whatever that could be an error...){
myAttLabel.setErrorFlag(true);
}
}
should do the job
But I think the answer of Josh Canfield is better

Because you can track the error within the component

This is what I am trying to do. But I could not pass the error flag from page
to component(AttLabel). I do not want to use @Persist to do this, but like
to add it to something like request object. So what annotation can I use?
Can you show me the way (some codes) to do this?

I you have control on the validation why not putting a flag in your
component when a validation error happen.
Your render process would depend of this flag.
does it help ?
Xinhua a écrit :
I create a custom component (AttrLable) which extends AbstractField. In
the
BeginRender(MarkupWriter writer), I will need to override the label tag
based on whether there is an error in the input field which is associated
to
this label.
On the form submission, I will do the form validation and if errors are
found, I will highlight the label and input field in the form page. But
the
problem is how I can pass the error flag to the component class
(Attrlabel)
which will rend the component.
Thanks in advance!
