Hi!
Normaly getClientId() would give you the unique id (at least the id
that denotes the correspondig html element). But see my last post,
about troubles with it.
Eventough it would output the correct value, you have do handle the id
inside the loop for generating you custom validation code,
because the ids will change every time your TextFields are rendered.
Problem is that the validation can only be done after the complete loop
is already rewound.
I checked all at the ValidationDelegate registered components but the
clientId of all of them is null at the time i can use them. So the only
possibility would be to generate a unique clientId (or better a unique
component-id) myself which i can also use the next time the page is
rendered to address the fields causing validation-errors or to build
another data structure parallel to my original beans to put the
information i need into...

Hi!
I got a small problem with a Tapestry application regarding components
in a for-loop. Inside this loop reside a couple of TextFields and
PropertySelection which i need to validate after all the data is written
to the beans. Problem now is that i need to address the components to
show the user in which of the components the validator found errors.
One of my tries was to get these components a custom and unique id which
i have the complete control over and therefore can reproduce. Didn't
work as getComponent(String id) goes for the name of the component, not
for the id. I also tried to set the name which got me an exception
telling me that i'm not allowed to do that...
Could anyone here help me out in this matter as i'm running a bit low on
ideas of how to address these fields?
Thanks in advance.
Patrick
