I have widget called List builder, which i used to sort list of contacts. when i submit the form the, i should get these sorted list of contacts in my $_POST array.

I am getting the content from CGridview widget but not from the following widget:




 $this->widget('ext.widgets.multiselects.XMultiSelects',array(

'leftTitle'=>'Email',

'leftName'=>'Contactlist[email][]',

'leftList'=>Contactlist::model()->findUsersByemail( ),

'rightTitle'=>'Email-List',

'rightName'=>'Contactlist[email][]',

//'rightList'=>Contactlist::model()->findUsersByemail( ),

'rightList'=>array(),

'size'=>20,

'width'=>'200px',

));

How to submit this widget data, so that i can access it from $_POST array?
