I have successfully got the Checkbox input to function, but when the post comes back the checkboxs aren't check with the values I have selected, they are all unchecked.

protected function defaultParamValues()
    {
        $case_subtype = CaseModel::select('case_subtype')->groupBy('case_subtype')->get();
        return array(
            "case_subtype" => $case_subtype->toArray()
        );
    }

    protected function bindParamsToInputs()
    {
        return array(
            "case_subtype" => 'case_subtype'
        );
    }

in the view blade..

CheckBoxList::create(array(
                        "name"=>"case_subtype",
                        "dataStore"=>$data->dataStore("data2"),
                        "dataBind"=>"case_subtype"
                    ));

I am using laravel, so when I pass the value to the view, I name the report value $data. I've dug into the code and the part where the checkboxes are generated it searches for the value in the array, but the value is never set. Below is a var dump of the checkbox at the bottom of the init function.

CheckBoxList {#746 ▼
  #dataBind: array:2 [▼
    "value" => "case_subtype"
    "text" => "case_subtype_full"
  ]
  #display: "vertical"
  #defaultOption: null
  #name: "case_subtype"
  #data: array:4 [▼
    0 => array:2 [▼
      "text" => null
      "value" => null
    ]
    1 => array:2 [▼
      "text" => "Complaint"
      "value" => "COMP"
    ]
    2 => array:2 [▼
      "text" => "Incident Report"
      "value" => "IR"
    ]
    3 => array:2 [▼
      "text" => "Mortality"
      "value" => "MRC"
    ]
  ]
  #value: []
  #attributes: array:1 [▶]
  #clientEvents: []
  #params: array:4 [▶]
  #report: WidgetContainer {#750 ▶}
  #assetManager: null
  #language: null
  #languageMap: null
  #dataStore: DataStore {#662 ▶}
  #onReady: null
  #themeBase: null
  #themeCssClass: null
  #withoutLoader: false
}

When the below line is executed, there is nothing in $this->value. $this->value is null.

<input type="checkbox" aName="<?php echo $this->name; ?>" name="<?php echo $this->name."[]"; ?>" value="<?php echo $value ?>" <?php echo(in_array($value,$this->value))?"checked":""; ?>>

The <input> above is rendered HTML inside the report view. It isn't rendering with $this->value. Below is the code in the view file. When I dump the values as the CheckBoxList class is called there is no value in $this->value; $this->name has the proper data in it. CheckBoxList::create(array(

      "name"=>"case_subtype",
      "dataStore"=>$data->dataStore("data2"),
      "dataBind"=>"case_subtype"

));

Figured out a work around, I manually get the values from $_POST and assign the "value" parameter to the CheckBoxList like below, if anyone else is having issues.

                                CheckBoxList::create(array(
                                    "name"=>"checkBoxList",
                                    "dataStore"=>$data->dataStore("data2"),
                                    "dataBind"=>array(
                                        "value" =>"case_subtype",
                                        "text"=>"case_subtype_full"
                                    ),
                                    "value"=>$_POST['checkBoxList'],
                                    "attributes"=>array(
                                        "class"=>"form-control"
                                    )
                                ));
