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.

Subject: Re: Marker for required fields on bean editor
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 :)
