CGridView via Ajax - error displaying pages/sorting

Yii 1.1 General Discussion
1

I’m trying to build a dynamic reporting section for my application ( using 1.1.1 )

I have the main index action for this controller creating a dual column display, in which the right column renders a partial _form. The _form submits via ajax to the left column div and displays the report details in a CGridView.

The initial ajax based partial render is called as such:





public function actionView()

{

   $reportOpt =new ReportsForm;

   ...  // basic init. for reportOpt 


   $dataProvider =new CActiveDataProvider('reportSummary', array(

					'pagination'=>array(

						'pageSize'=>10,

					)


				));


   $this->renderPartial( 

           "_".ReportsForm::$_reportTypes[$reportOpt->reportType]['action'],

           array('formOptions'=>$reportOpt, 'dataProvider'=>$dataProvider), 

           false, 

           true);

}

In the partial view:




$this->widget('zii.widgets.grid.CGridView', array(

	'dataProvider'=>$dataProvider,

	'ajaxUpdate'=>'ajaxContent',

	)

);

To this point, everything works great.

However, whenever I try to use the column sorting and pagination, it displays the loading icon, then the div is updated with no content.

I feel like I must be missing something very basic and wonder if anyone can point me in the right direction please.

Ok, I don’t know if I’m just doing something so off the wall that no one else would bother, but just in case someone else is trying to do similar, I ended up using the following solution:

Quick Recap: Right side of page is form options (search criteria) which I don’t wish to generate each time, Left side of page is resulting report display from DB data in a CGridView format.

In my Controller, I added a loadModel function to be used for all the actions to get the proper form data. Then I set the loadModel up as follows (note, requires configuring site cache):




public function loadModel()

{


    if ( $this->_model === null )

    {

        $this->_model = new ReportsForm;

        

        if ( isset($_POST['ReportsForm']))

        { 

            $this->_model->dtEnd=$_POST['ReportsForm']['dtEnd'];

            .... // etc. all form options

            // THIS IS THE KEY - cache the model

            Yii::app()->cache->set('report_form', $this->_model );


        } else {

            $this->_model->defaults(); // call up my preset default form options jic this is first time

            if ( $tmp = Yii::app()->cache()->get('report_form') )

               $this->_model = $tmp;

        }

    }

    return $this->_model;

}

Now the ajax updated view always has access to the form fields.

Can anyone see any major flaw in this plan which I might be overlooking in my Yii-noobness?
