[Trinidad]How to do dynamic form validation?
Dear all,
I have a form which has two <tr:inputText> elements, if first element has
value, then the second element must have value as well. If first element
doesn't have value, then the second element is optional.
Vice versa, if the second element has value, then the first element must
have value. If the second element doesn't have value, then the first element
is optional.
How can I implement this in trinidad? Thanks in advance!
Kind regards,
Leon

does not help
on initial rendering, when both values ARE null, there is required than
He wants to do some more advanced validation, based on IF there were
actually values submitted.
I'd use the ExtVal framework for that

Posted by Döring Markus <Ma...@tcc-products.de>.
Hi,
I didn't tested it, but maybe something like this works for you:
<tr:inputText label="textfield1" value="#{value1}" required="#{value2 != null}">
<tr:inputText label="textfield2" value="#{value2}" required="#{value1 != null}">
Maybe you have to replace "valueX != null" with some kind of "isNotBlank(valueX)" and you have to add some PPR stuff to update textfield2 if value of textfield1 changess (and vice versa)

I'd check out ExtVal, from MyFaces as well:
