el question - expression

This might be OT, apologies in that case.
Have this button

<a4j:commandButton value="Save" action="#{myController.save}"
oncomplete="#{facesContext.maximumSeverity == null ? 'Richfaces.hideModalPanel(\'myModalPanelId\');' : ''}" />

How can I make the modal panel id a variable to use it in a facelets template. This doesn't work but to illustrate:

<a4j:commandButton value="Save" action="#{myController.save}"
oncomplete="#{facesContext.maximumSeverity == null ? 'Richfaces.hideModalPanel(\''+ myModalPanelIdParam +'\');' : ''}" />

As far as I know, JSF has no standard means of concatenating strings, maybe Seam has some - are you using it?

Concatenating is possible in Facelets:

<c:set var="concatenationResult" value=" '#{panelId}' " />

, then use

#{concatenationResult}

Saem did indeed have a function http://seamframework.org/Documentation/HowDoIConcatStringsInFaceletsTemplates

solution:

<a4j:commandButton value="Save" reRender="#{rerender}" action="#{actionBean[action]}"
oncomplete="#{facesContext.maximumSeverity == null ? 'Richfaces.hideModalPanel(\''.concat(panelid).concat('\');') : ''}" />
