[T4] Validation Problem

[Christian Haselbach <ch...@tngtech.com>]

Hi,

I'm using a required validator on a TextField and use the form delegate
to check whether there is an error in the TextField. If so, I render an
error message. However, this message is rendered before the input-field
is rendered.

The problem starts when I have this TextField in a For loop. Now a
validation error message is shown an the next TextField, instead of the
TextField that really has the problem.

Interestingly, if the last TextField is wrong, the first TextField gets
the error message.

Anyone knows a solution?

Thanks and regards,
Christian

Hi again,

a colleague of mine gave me a hint: Look at FieldLabel. FieldLabel
handles exactly the same problem and uses preRender(). I could solve it
analogous.
