T5 - BeanEditForm server side validation question

Simple question from a noob: Following form example, mostly works
well. Now I want to do some cross validation server side, and can do
that, however I cannot figure out how to set the error message on
the form.

My class has:

@Inject
private BeanModelSource _beanModelSource;
	
@Inject
private ComponentResources _resources;

@Retain
private BeanModel _model;

etc..

but no form object.

The template has

<t:beaneditform object="bean" model="model">

It seems to me that I need to get the form object and use
recordError(String err), is that right? How do I access the form if
it is not in my class?

Thanks in advance, really impressed with T5 so far.

Chris

Very good. For completeness for anyone else reading this, I did the
following:

Added to the java class

@Component
private BeanEditForm _form;

public BeanEditForm getForm()
{
    return _form;
}

and changed template to ( notice the <t:beaneditform to <:form )

<t:form id="form" object="bean" model="model"/>	

Thanks!

Hi Chris,

Simply inject the BeanEditForm into your page class and use that to 
record the errors. You'll need to give the BeanEditForm an id in your 
template and then use the @Component annotation to inject it.

Details are here:
