Conditional Tabs (show/hide)

Question

I'm trying to hide certain tabs based on the condition of
whether they recieve content or not.
Apparently, applying
... visible="{(someTextInput.text.length == 0) ?
false:true}"
doesn't work with tabs.
What's the correct approach with tabs?
Thanks,
James

here you go as your post says during application
initializtion to remove all children after first occurrence of tab
without a label right?
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:Script>
<![CDATA[
import mx.controls.TextInput;
import mx.controls.Alert;
private function checkTabs(e:Event):void
var _nolabel:Boolean = false
for each(var childTab:Canvas in
mytabnavigator.getChildren()){
if(childTab.label=="") _nolabel = true;
if(_nolabel) {
mytabnavigator.removeChild(childTab);
]]>
</mx:Script>
<mx:Canvas id="mycanvas" >
</mx:Canvas>
<mx:TabNavigator id="mytabnavigator" creationPolicy="all"
creationComplete="checkTabs(event)" x="155" y="207" width="200"
height="200">
<mx:Canvas label="One" width="100%" height="100%">
</mx:Canvas>
<mx:Canvas label="two" width="100%" height="100%">
</mx:Canvas>
<mx:Canvas label="three" width="100%" height="100%">
</mx:Canvas>
<mx:Canvas label="four" width="100%" height="100%">

<mx:Canvas label="" width="100%" height="100%">
