No, firstTab is an instance on an object that lives in your composite
component. First Name for example. When you implement your composite
component you could have the following code in the childrenCreated of your
implementation class:
override protected function childrenCreated():void
{
super.childrenCreated();
compositeComponent.firstTab = this.FirstName;
}
