a4j:commandButton's oncomplete does not wait for a4j:param

[julez]

Hello,

I have for each row inside a rich:dataTable an a4j:commandButton to show a popupPanel, which works so far.

Now I want the commandButton also to change the content of the popupPanel, according to the row in which the commandButton sits. Passing a param value with a4j:param works, but the panel gets always rendered BEFORE the param is passed.

My source for the commandButton looks like the following:

<a4j:commandButton value="(PSM in cluster)"
     render="popup_content"
     execute="@this"
     oncomplete="#{rich:component('popup_panel')}.show(); return false;">
     <a4j:param assignTo="#{cc.attrs.psmViewerBean.popupData}" value="#{psmRow.id}" />
</a4j:commandButton>

The popupPanel is outside every form at the end of the document.

The psmRow is the iterating element of the dataTable and its ID gets passed to a function of the backing bean.

The popup_content is a a4j:outputPanel inside the popupPanel which is bound via binding to a bean component, which should also update the content and does, but, as said, always after the rendering, so it is shown always on the next click.

Any ideas how I could pass any relevent row parameter and then render the popupPanel?

Tanks,

Julian

After trying out several things I found a workaround with a jsFunction. My code now looks like this, it unfortunately loads the popupPanel twice, but that's ok for now.

I set the data via the jsFunction:

<a4j:jsFunction name="updatePopup" render="popup_panel">

     <a4j:param name="id" assignTo="#{cc.attrs.psmViewerBean.popupData}"/>

</a4j:jsFunction>

And the buttons call the jsFunction via the onclick

<a4j:commandButton value="buttontext"

                    render="popup_panel"

                    execute="@this"

                    onclick="updatePopup(#{psmRow.id});"

                    oncomplete="#{rich:component('popup_panel')}.show(); return false;"/>
