@RAPHAEL,
i tried it as follows:
$widgetSchema = $this->form->getWidgetSchema();
$validatorSchema = $this->form->getValidatorSchema();
unset($widgetSchema['foo']);
unset($validatorSchema['foo']);
$this->form->setWidgetSchema($widgetSchema);
$this->form->setValidatorSchema($validatorSchema);
$this->form->resetFormFields();
but no, it wont work :(
@Ryan:
it tried it both ways, using sfFormFieldSchema::offsetUnset throws a
"read only" exception, and unset($form['foo']) simply does nothing,
the widget and validator still exists in the schemas.
why is the sfFormFieldSchema is throwing an exception on unsetting
fields through ::offsetUnset. I think it cant be very complicated the
remove widgets and validators after instanciating? or am i missing
something fundamental?
But i think there must be a way to achieve this, if i am able to do
"unset($this['foo']);" why not "unset($form['foo']);" and why the form
frameworks prevents it through sfFormFieldSchema::offsetUnset?
Too many questions left :(
