f:attribute or tc:attribute not working?

[Thomas Schmitz]

Hello,

I am trying to do something like following. The f:validator tag works but
the f:attribute seems not to work.

<tc:in value="#{policy.productId}">

<f:validator validatorId="custom.validator"/>

  <f:attribute name="constraint" value="#{constraints.stringLength(3,
15)}"/>

</tc:in>


The way I try to get the constraint attribute within my custom validator is:


component.getAttributes().get("constraint");


I tried to find out where the attribute must be set, with no success. Can
you give me a hint where to debug, please?


Regards,

Thomas
