Hello.
I'm using DynaValidatorForm and I'm using the validator. It works fine but I have a field who appears only if I click a button. I want to validate that field too but if is not present every time appears the validation for that field.
So I want to validate only if is present. There is something like this ?
Thanks.

How are you hiding the field? If you are just hiding it with styles it will still be submitted with the form.

I don't hide the field. I have something like this:
<logic resent name="test">
<html:text property="field1">
</logic resent>
I hope is clear.
Thanks.
