(this might be a sneaky way of asking a different question about datascrollers...)

Say I have a binding like
#{dataModel.curPage}

Is there some kind of ajax call I could make from javascript to get the current value of that element?

Something where I could go like

var currentPage = SomeFunction("dataModel.curPage"};
alert("current page is "+currentPage);

but the SomeFunction would of course have to have some kind of communication with the server?

Is this a very typical "binding" activity, or does binding refer only to tying in the controls to the values statically, so to speak?

Any thoughts on this?

Is it that silly of a question?

You'd need to formulate it as an AJAX query. JavaScript runs on the client (browser). The backing beans live in the server. So the client will have to query the server to get the bean value.

Tim, yes, I understand that it would have to be an AJAX query...
my question is, is there some kind of javascript/AJAX library API call already there that I could use for this?
