tapestry zone update with post field in request

Question

is there way to update tapestry zone by ZoneManager with POST field in request to server?

this works fine...

var zoneManager = Tapestry.findZoneManager($('textarea'));
var listenerURIWithValue = this.listenerURI;
listenerURIWithValue = this.addRequestParameter('param', $('textarea').value,     listenerURIWithValue);
zoneManager.updateFromURL(listenerURIWithValue);

but what if I have too long string in textarea? I need to send the $('textarea').value as a POST, not GET.

Has anybody an idea? Thank you for your responds.

I listed in Tapestry-prototypejs source code and finally I found the solution. Function updateFromUrl has another parameter.

zoneManager.updateFromURL(listenerURIWithValue, 
        {
            "method": "post",
            "parameter": $('textarea').value
        });
