Form field reloaded stops form submitting correctly

[Gowrav Vishwakarma]

Here is my simple code

if I comment bold line form submits okey but if I keep it all looks normal, the other dropdown populates very well but at the time of form submission it given Ajax error.

if($crud->form){

            $item_field=$crud->form->getElement('item_id');
            $rate_field=$crud->form->getElement('rate');
           
            if($_GET['changed_item']){
                $itm=$this->add('Model_Item_Inward');
                $q=$itm->dsql()->del('field')->field('DISTINCT(rate) collected_rate')->where('item_id',$_GET['changed_item']);
                $r_array=array();
                foreach($q as $junk){
                    $r_array += array($junk['collected_rate']=>$junk['collected_rate']);
                }
                $rate_field->setValueList($r_array);   
            }

            $item_field->js('change',$crud->form->js()->atk4_form('reloadField','rate',array($this->api->url(),'changed_item'=>$item_field->js()->val())));

        }

This type of error is giving problem on almost every where where we are using reloaded form field elements, we are on atk 4.2.2

just a guess, but when that reload request is happening, does it pass enough GET arguments to have a working Form object to respond to the query?

No, it is not working and problem is not this.
The problem is Model has a field which has setValueList on it with some predefined values.
if we populate the field with new values and submit the form it still try to get values from the initial set and throws exception that submitted value of the populated drop down is not from the offered list...

is there any workarround for this situation .. in CRUD.

[Romans Malinovskis]

  function validate(){

        if(!$this->value)return parent::validate();

        $this->getValueList(); //otherwise not preloaded?

        if(!isset($this->value_list[$this->value])){

            $this->form->errors[$this->short_name]="This is not one of the offered values";

        }

        return parent::validate();

    }

Somehow you should change that in your dropdown. You can extend the field

class Form_Field_MyDropdown extends Form_Field_DropDown {

  function validate(){

     if(!isset($this->value_list[$this->value])){

        $this->value_list[$this->value]=true;

     }

    return parent::validate();

  }

}
