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...
