[FLOW3-general] Mapping data on existing objects

[Regine Rosewich]

Hi Pascal,

I suppose, it would be helpful for you to have the persistence_identifier of
the objects transferred to ExtJs via ExtDirect (even if you keep them hidden
on the ExtJS-Side). This can be achieved by using the
"_exposeObjectIdentifier" Property in the ExtDirect\View as show in the
example below.

class StandardView extends \F3\ExtJS\ExtDirect\View {
	
 	/**
 	 * @param array $data the data to be listed
 	 * @return void
 	 * @author Regine Rosewich - aurum GmbH, Freiamt
 	 */
 	public function completeList($data) {
 		$this->setConfiguration(
 			array(
	 			'value' => array(
 					'data' => array (
 						'_descendAll' => array(
 
'_exposeObjectIdentifier' => TRUE
 						)
 					)
	 			)
	 		)
 		);
		$this->assign('value', array('data' => $data, 'success' =>
TRUE,));
 	}
 	
 }

If you furthermore work with Ext.data.Model classes on the ExtJs Side you
can there use the property 'idProperty' and ExtJs will always incorporate
the persistence_identifier into the JSON Requests.

Ext.define('F3.WeluPdm.Module.Stammdaten.Data.AuspraegungModel', {
	extend: 'Ext.data.Model',
	alias: 'widget.F3.WeluPdm.Module.Stammdaten.Data.AuspraegungModel',
	idProperty: '__identity',
	fields: ['auspraegung', 
	         'bezeichnung',
	         ]
});

Hope it helps.
