It's usefull to set information rendered to the view in order to be retrieved from the event handler. i.e.
<comp:datacollector name="invoice_info"> <comp-property name="invoice_id">{$invoice_id}</comp-property> <comp-property name="client_id">{$client_id}</comp-property> </comp:datacollector>
Once we have stored information from the view to the data collector, we can retrieve it from the event handler. i.e.
public function beforeRender() { $invoice_data_collector = $this->getComponent('invoice_info'); //get the invoice id as well as the client id: $invoice_id = $invoice_data_collector->invoice_id; $client_id = $invoice_data_collector->client_id; }
The data collector is not poolable, which means that can be retrieved only in create and beforeRender events.
