How to trigger a bean function on rendering

[chris24]

Hi,
i have to trigger a bean function after a component is triggered or a page is finally load. I can not make use of the body onload="" function.
Is ther a way to trigger bean fucntions with RichFaces after a page is completely loaded or a component is finally rendered?

Regards,
Chris

For ajax requests use oncomplete attribute to fire some JS functions or maybe even new ajax requests after current completed.

If you talking about standard GET to page or POST with standard controls then the answers only common ones - onload event or maybe some inline scripts in the page end.

Seam can do that.

Oh, I'm wrong. Seam will execute that bean function before the page is rendered.

can you give an exapmle how to implement this?

You can try this:

<a4j:jsFunction name="coolMethod" ... /><script type="text/javascript">coolMethod();</script>

jsFunction can be called inside jQuery(document).ready(): http://www.learningjquery.com/2006/09/introducing-document-ready if you are in the case when defining inline onload handler for BODY element is not possible for some reason.

OK, thanks a lot!
Actually i got it with your help. Here is the Code:

<a4j:jsFunction name="getContactList" immediate="true" action="#{myBean1.fetchContacts}" reRender="contacts" />
<a4j:jsFunction name="getAddressList" immediate="true" action="#{myBean2.fetchAddresses}" reRender="addresses" />


//<![CDATA[
Event.observe( window, 'load', function() {
getContactList();
getAddressList();
} );
