Marker for required fields on bean editor
Hi all!
Is it possible to mark the required fields inside a beaneditor form as
valid? I know i could override the field declaration and put the
marker there but i would like to create something more generic.
I was thinking that a Mixin may get the beaneditor's form to get all
the components in the form, iterate over the validators and add the js
or mark to the ones with a required validator but i am not sure how to
accomplish this. Is it possible at all? Has anybody done such thing?

I've finished something like that before.
First create a mixin 'FieldDecorator', then need contribute to the BeanBlockOverrideSource.
Here is the sample code:
1.
@MixinAfter
public class FieldDecorator {
@InjectContainer
private AbstractField field;
@Inject
private ComponentResources resources;
void cleanupRender(MarkupWriter writer)
{
if (field.isRequired()) {
writer.element("font", "color", "red");
writer.writeRaw(" * ");
writer.end();
}
}
2. Contribution, override the default edit block in page PropertyEditBlocks.java.
public static void contributeBeanBlockOverrideSource(Configuration<BeanBlockContribution> configuration) {
configuration.add(new BeanBlockContribution("text", "CustomEditBlocks", "text", true));
}
You need write your own CustomEditBlocks.java and CustomEditBlocks.tml to do something like PropertyEditBlocks.java and PropertyEditBlocks.tml, then just put the mixin 'FieldDecorator' there.

Sorry Sebastian, i was not clear enough.
I want to change the markup of the label when the field has a required
validator. For example i want to add a CSS class required to the label
of the required field. or i want to add a * next to the label.
Thanks for ur answer :)
