zoneManager keeps being null

[sommeralex <al...@gmail.com>]

Hello, , 

I have a wired problem. My ZoneManager keeps being null:

JS:

function updatePage(response){
	alert ("id: " + zoneId);
	alert (urlSetMsgPositionAndSize);
	var zoneManager = Tapestry.findZoneManagerForZone(zoneId); 
	
	alert ("zone " + zoneManager);
	zoneManager.updateFromURL(urlSetMsgPositionAndSize); 
}

alert zone gives "zone null", but urlSetMsgPositionAndSize is
/message/createmessage3:setmsgpositionandsize?t:ac=90

and alert of alert ("id: " + zoneId); is "[object HTMLdivelement]"

my js loader functions:

function initializeOnLoad(centerX, centerY, _scopeRadius,
_minMsgScopeInMeters, _maxMsgScopeInMeters, _urlSetMsgPositionAndSize,
_zoneId) {
	google.maps.event.addDomListener(window, 'load', initialize(centerX,
centerY, _scopeRadius, _minMsgScopeInMeters, _maxMsgScopeInMeters,
_urlSetMsgPositionAndSize, _zoneId));	
}

function initialize(centerX, centerY, _scopeRadius, _minMsgScopeInMeters,
_maxMsgScopeInMeters, _urlSetMsgPositionAndSize, _zoneId) {
	 
	var mapOptions = {
			    zoom: 12,
			    center: new google.maps.LatLng(centerY, centerX),
			    mapTypeId: google.maps.MapTypeId.ROADMAP
			  };
	  
	  map = new google.maps.Map(document.getElementById("map_canvas"),
mapOptions);
	  urlSetMsgPositionAndSize = _urlSetMsgPositionAndSize;
	  
	  alert (urlSetMsgPositionAndSize);
	  
	  zoneId = _zoneId;
	  
	  scopeRadius = _scopeRadius;
	  minMsgScopeInMeters = _minMsgScopeInMeters;
	  maxMsgScopeInMeters = _maxMsgScopeInMeters;

	  google.maps.event.addListener(map, 'dragend', onMapDragEnd); 
	  
	  google.maps.event.addListenerOnce(map, 'idle', function(){
		  onSlide(scopeRadius);
		});
	  
	  setMarker(map.getCenter());
}

my java class has a 

	@InjectComponent
	private Zone updateZone;

which is a parameter for my JS call:

Link linkSetMsgPosAndSize =
componentResources.createEventLink("setMsgPositionAndSize");
		javaScriptSupport.addScript("initializeOnLoad(%s, %s, %s,%s,%s,'%s',
%s);", groupCenter.getCentroid().getX(), groupCenter.getCentroid().getY(),
group.getMessageRadius(), group.getMinMessageRadius(),
group.getMaxMessageRadius(), linkSetMsgPosAndSize.toURI(),
updateZone.getClientId());


i did the same for another page where it is working. but here it keeps
saying that the zoneManager is null. tge tapestry page itself shows the
error message:

updateZone does not have associated Tapestry.ZoneManager object.

fixed. it seems that i just had to take care of the right order of loading
the js snippeds (setupRender, afterRender were confused in my code)
