Its is correctly ? Im be utilize a4j:commandLink to rerender

[peerless]

Friends, i have a popup that execute the following js function:

function doAjaxOpener() {
 opener.document.getElementById('form:update_datatable').onclick();
}

Him is invoked on click of save button:

<h:commandButton styleClass="Button" value="Save" action="#{plano.saveFamily}" onclick="doAjaxOpener();"/>

Then, it´s invoke the commandLink (present on my opener page) that update my datatable:

<a4j:commandLink id="update_datatable" reRender="data" />
<t:dataTable id="data"...

It´s work, no problem!!!! But, it´s a good pratice? I can have future problems?

-> If the action #{plano.saveFamily} sleep for any seconds.. and later work, my commandLink will ir update my datatable too?

Thanks very much!
