Cannot do filtering via a dropdown menu in Yii TbGridView (v1.x.x) - yii

Question

I am trying to get the filtering to run although I am having some issues below is my view note that this in in a PARTIAL view :-
If I click on the header of the column it does the sorting as expected, however if I select an option from the dropdown it doesn't filter the items...
Any ideas?
<?php
$myuser = new Myuser('search');
$filterBtn = $this->widget('bootstrap.widgets.TbButton', array(
'icon' => 'filter',
'size' => 'small',
'label' => $myuser->paging ? 'View All' : 'View Less',
'htmlOptions' => array('class'=>'pull-right', 'style'=> 'margin:20px 0;'),
'url' => $myuser->paging ? array('/carrot/myuser/admin/paging/0') : array('/carrot/myuser/admin')
), true);
$this->widget('bootstrap.widgets.TbGridView',array(
'id' => 'myuser-grid','type'=>'striped bordered condensed',
'dataProvider' => $myuser->search(),
'filter' => $myuser,
'columns' => array(
array(
'id' => 'user_id',
'class' => 'CCheckBoxColumn',
'checked' => 'in_array($data->user_id, $this->grid->owner->model->student_ids)',
'checkBoxHtmlOptions' => array(
'name' => 'selected_student_id[]',
)
),
'firstname',
'surname',
'username',
array(
'name' => 'year_id',
'filter' => CHtml::activeDropDownList($myuser, 'year_id', CHtml::listData(Organisation::model()->distinctYears, 'year_id', 'year_id'), array('prompt'=>'All Years')),
'htmlOptions' => array('style' => 'text-align:center;'),
'headerHtmlOptions' => array('style' => 'text-align:left;'),
),
array(
'name' => 'form_name',
'header' => 'Form',
'filter' => CHtml::activeDropDownList($myuser, 'form_name', CHtml::listData(Organisation::model()->distinctForms, 'form_name', 'form_name'), array('prompt'=>'All Forms')),
),
array(
'name' => 'House',
'filter' => CHtml::activeDropDownList($myuser, 'House', CHtml::listData(Organisation::model()->distinctHouses, 'House', 'House'), array('prompt'=>'All Houses')),
),
),
)); ?>
My model has the following search() method:
public function search($limit = false)
{
$criteria = new CDbCriteria();
$criteria->compare('t.user_id',$this->user_id,true);
$criteria->compare('t.firstname',$this->firstname,true);
$criteria->compare('t.surname',$this->surname,true);
$criteria->compare('t.username',$this->username,true);
$criteria->compare('t.year_id',$this->year_id);
$criteria->compare('t.form_name',$this->form_name);
$criteria->compare('t.House',$this->House);
$criteria->compare('o.organisation_id',$this->organisation_id);
$criteria->group = 't.user_id';
$criteria->together = true;
return new CActiveDataProvider($this->currentUserOrganisation(), array(
'criteria' => $criteria,
'pagination' => array(
'pageSize' => $this->paging ? ($limit) ? $limit : OverviewController::PAGE_SIZE : 2000
),
'sort' => array(
'defaultOrder' => array('firstname'=>false, 'surname'=>false),
'attributes' => array(
'organisation_name' => array(
'asc' => 'organisation_name',
'desc' => 'organisation_name DESC',
'default' => 'desc',
),
'*'
)
),
));
}

I think you can't use a DropDownList as filter, but you can easily use CHTML::listData():
array(
'name' => 'year_id',
'filter' => CHtml::listData(Organisation::model()->distinctYears, 'year_id', 'year_id'),
'htmlOptions' => array('style' => 'text-align:center;'),
'headerHtmlOptions' => array('style' => 'text-align:left;'),
),
array(
'name' => 'form_name',
'header' => 'Form',
'filter' => CHtml::listData(Organisation::model()->distinctForms, 'form_name', 'form_name'),
),
array(
'name' => 'House',
'filter' => CHtml::listData(Organisation::model()->distinctHouses, 'House', 'House'),
),
This will automatically generate a DropDownList for you.
I hope this works for you.
