I am using Zend Form to create dynamic form.
I have Zend Form validation too.
Trying to remove Validation dynamically, but not getting any success.
C
Your code is removing a validator by name
$value->removeValidator('ele_4af42ceac7810');
This is typically something like NotEmpty or Regex as opposed to the element name.
NotEmpty
Regex
Maybe you want
$value->clearValidators();
Also, +1 Ismael - you should remove it prior to calling $form->isValid()
$form->isValid()
