Hey Nick,
I used this as a test case.... its stripped down from what you are doing but maybe it will point you in the right direction.
<?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx=" http://www.adobe.com/2006/mxml" layout="vertical" creationComplete="init()">
<mx:Script>
<![CDATA[
import mx.containers.Canvas;
import mx.core.Container;
private function init():void {
trace(tabExists('test'));
windowTab.addChild(newTab('test'));
trace(tabExists('test'));
trace(tabExists('test2'));
windowTab.addChild(newTab('test2'));
trace(tabExists('test2'));
trace(tabExists('test3'));
}
private function tabExists(str:String):Boolean {
return windowTab.getChildByName (str) != null;
}
private function newTab(str:String):Canvas {
var tmpcon:Canvas = new Canvas();
tmpcon.percentWidth = 100;
tmpcon.percentHeight = 100;
tmpcon.id = str;
tmpcon.name = str;
tmpcon.label = str;
return tmpcon;
}
]]>
</mx:Script>
<mx:TabNavigator id="windowTab" width="100%" height="100%">
</mx:TabNavigator>
</mx:Application>
shows in the console:false
true
false
true
false
Maybe we need to just change the if statement so it checks for null
if ( selectTab != null )

var selectTab:Container = this.windowTabs.getChildByName(newid);to
var selectTab:Container = Container(this.windowTabs.getChildByName(newid));
Or
var selectTab:Container = this.windowTabs.getChildByName(newid) as Container;
Im not sure which syntax is the correct way or what the difference is. Anyone care to explain the difference?

You could assign a name to your tab and then use
this.windowTabs.getChildByName( newtab.name);
Something like
private function createTab(createTabName:String):void
{var newid:String = 'userTab' +
this.masterList.selectedItem.ContribNum;
var selectTab:Container = this.windowTabs.getChildByName(newid);
if(!selectTab) {
var newVbox:VBox = new VBox();
var newHbox:HBox = new HBox();
var newTab:Canvas = new Canvas();
var newSpacer:Spacer = new Spacer();
var tabCloseBtn:Button = new Button();
// create button to close tab
tabCloseBtn.label = "Close Tab";
tabCloseBtn.addEventListener
(MouseEvent.CLICK,myClickListener);
// create spacer to position close button
newSpacer.percentWidth = 100;
// create box layout controls
newHbox.percentWidth = 100;
newHbox.addChild(newSpacer);
newHbox.addChild(tabCloseBtn);
newVbox.addChild(newHbox);
newVbox.addChild
(getTithesComponent(this.masterList.selectedItem.ContribNum));
// create tab
newTab.label = createTabName;newTab.id = newid;
newTab.name = newid;
newTab.addChild(newVbox);
this.windowTabs.addChild(newTab);
this.windowTabs.selectedChild = newTab;
}
