Re: editing response in onComponentTag
Hi,
Better use a Behavior that is attached to SimpleFormComponentLabel.
Use #beforeRender() to prepend the asterisk.

RequiredLabel is a label that is used with a FormComponent. It is used to
put the red asterisk to show that input to the field is required. But
what
happens is that on an ajax request the red asterisks keep on piling up.
And
I have a case where the field may be changed to be not required. How do I
remove the previosly placed red asterisk?
Thanks.
