Can seam component property be set with a4j:actionparam before a4j:status is invoked?

[jgreene]

Hello -

We use the a4j:status component extensively throughout our application in conjunction with the "status" attribute on command buttons.  The "onstart" property in the a4j:status component is used to show a rich:modalPanel component where we show a "Loading..." message and an image to indicate that we are waiting.  "Loading..." in the panel's header is hard-coded.  We would like to make this label dynamic based on where this status widget is called from.  For example, if we click a button to begin loading some file, we would want to display this modal with the label reading "Loading Files..." maybe, and if the modal is invoked when a button is clicked to, say, delete a user, we would like the label on the modal to read "Deleting user...", etc.

We thought the natural solution to this would be to use an a4j:actionparam inside the a4j:commandButton component that invokes the action, and use the param to set the label in a ProgressBar seam component.  But apparently the status widget is invoked immediately since, of course, it is part of the ajax action, and the param value assignment has not yet taken place.

Has anyone done this before?  Maybe we are making a simple mistake or a bad assumption and just need a nudge in the right direction.

Any help would be appreciated.  Thank you.

general comments on approach.

It's god to make dynamic updates of some label via ajax in general but status component is special case and this will not works there:

Status component switching to start state when request starts and finishes after it's ends. So if you trying to use a4j:param - param will be passed and applied during current request(when statuus already shows progress) and will not be actual (as it will be applied after the status for the request already hidden).

So you should have change the label in modal panel on client side using the same onstart even (change inner html in some label span and then show the modal)

Thank you, Ilya - yes, I realized after it did not work that the approach I took has a problem for the reasons you said.  I will try your suggestions.  Thanks again.
