BeanEditForm recorderror for a field
Hello,
the beaneditform provides a method recordError which expects a field of
the form. I couldn't find out, how I can get a reference to a field
of the form.
I would like to call
myForm.recordError(myInputField, "bad problem");

I do not fully agree here. I use the beaneditform to get rid of
t:textfield and t:label components. I don't want to fall back on normal
form writing. To record errors for single fields when doing cross field
or custom validations should be possible in beaneditform as well.
However, I suppose it'd be entirely

I checked the code and I would need to introduce the following code in
the following classes (typed without compiling)
BeanEditForm
public void recordError(String fieldName, String errorMessage)
{
form.recordError(fieldName, errorMessage);
}
org.apache.tapestry5.corelib.components.Form and the interface
FormValidationControl
public void recordError(String fieldName, String errorMessage)
{
tracker.recordError(fieldName, errorMessage);
}
org.apache.tapestry5.ValidationTracker
org.apache.tapestry5.ValidationTrackerImp
public void recordError(String fieldName, String errorMessage)
{
FieldTracker ft = get(fieldName);
ft.errorMessage = errorMessage;
store(ft);
}
+ the get method
Before I write a patch, I would like to know from the core comitter if
this is likely to be included?

I don't see it as a workaround considering that you'd do exactly the
same if it was a regular form. However, I suppose it'd be entirely
possible and likely even easy to implement a getField(String
propertyName) for BeanEditForm. Maybe open an issue for it?

Re: BeanEditForm recorderror for a field
Posted by Sebastian Hennebrueder <us...@laliluna.de>.
I found this solution 5 minutes ago but thought it was a workaround. To
allow cross field validation, it would be nice
if the beaneditform provides access to the fields uses internally.
What do you think?

No, you don't /have/ to, at least I can't imagine a situation. If you are giving your templates away
to a designer you probably want to define all of your component's parameters in the component class
and then you have to use @Component. You just have to realize that parameters defined within
@Component take precedence over those specified inside the template. Apart from that
@InjectComponent and @Component yield the same result. I believe though, that it's good style to use
@InjectComponent when you just want to record a validation error for a specific field and don't want
to actually define a component.

Oh that - you need tell the bean editor that you want the field to be
used in your form. See Property Editor Overrides at
http://tapestry.apache.org/tapestry5.1/guide/beaneditform.html, e.g:
<t:beaneditform object="formModel">
<t:parameter name="country">
<t:label for="country"/>
<t:textfield t:id="country" value="formModel.country"/>
</t:parameter>
</t:beaneditform>
Ulrich - in practice, is there a case when you would have to use
@InjectComponent over @Component with T5?

That's not 100% correct. @Component defines a component in your
component class that you can then use in your template while
@InjectComponent injects a component defined in your template.

How do you reference your myForm? All components are handled the same way:
@Component
private TextField myInputField;
