BSP: How copy received portal event string to ABAP-Page-Attribute variable?

Question

Hi,
I am able to receive and display portal events (EPCF API) with the following code:
<SCRIPT src="epcfproxy.js"></SCRIPT>
<script language="javascript">
if(window.document.domain == window.location.hostname){
document.domain = document.domain.substring(document.domain.indexOf('.')+1);
    EPCMPROXY.subscribeEvent("urn:com.sap:BWEvents","BWiViewevent", window, "myreceiveEvent");
function myreceiveEvent( eventObj ) {
   alert("event received:" + eventObj.dataObject );
But now the received data is only stored in Javascript-"variables".
How can I copy the received string to ABAP variables? These variables will be declared as Page Attribute (e.g. rec_event_data  TYPE STRING)
Is my Javascript-solution a good way to handle portal events or are there better solutions?
Thanks a lot.
Regards,
Henning

Hi,
yes I was able to do it.
The code should be something like this. I can not test it at the moment.
function myreceiveEvent( eventObj )
        document.form1.rec_event.value = eventObj.dataObject;
        document.form1.submit();
<htmlb:form id="form1">
      <input type="hidden" name="rec_event" value="">
</htmlb:form>
Event Handler: OnInputProcessing
rec_event_data = request->get_form_field('rec_event').
