Hi manuel, hmm, let me clarify, i have code like this:



and I want the myFunction() to be called, but only when the action #{someBean.itemClicked} has finished executing.

i can for example not use onComplete attribute since it is just looking at the client side and not on the server side....

This gets back to the issue about JSF being based on HTTP and HTTP being a request/response protocol.

When you fire an Action, a request is made to the server. The request is processed as per the JSF lifecycle specs and a response is sent back to the client. The response is going to be a complete HTTP page.

So the answer is: implement an onLoad() JavaScript method. If it will be used on the same page that the request was made from but only after updating, set a page variable that the onLoad method can use to tell it's a reload.
