Redundant transmission of array parameter to form

[VladaHejda]

If there is an array parameter of some presenter action (eg. function actionDefault(array $animals) and the form with equal named input (with array value, eg. $form->addMultiSelect('animals', ...)), then after the form si sent, values of that input are added to the form as hidden fields. In case of scalar input this is not happening and is should not occur either with array input.

When these hidden fields are present in the form, next send of the form has unexpected behavior.

This is the limitation that can not be soved. Just the names of (GET) form elements and presenter parameters collide.
