You are correct, this is because TabNavigator hides it's children.

What are you trying to do?

Cheers,

 so the script will take a form object, then see how many childreen 
it
 has then it will send the formitems to FrmI. Frmi will get me the 
name
 of the child objects and that is all.  So the problem is when I run 
init()
 public function init():void
 {
   Frm(FormOne);
   Frm(FormTwo);
 }
 I get this in return:
 fname

 If I just run the 2nd form like this:

My current project has a very long form so I decided to break it down
into multiple panes on a TabNavigator.

So, each pane has its own specific form details. When the user clicks
the Next button, it checks all the form fields for data and populates
a value object with this data. It then dispatches a custom event which
contains this value object. I listen for this event at the application
level as well as the container of the TabNavigator. The application
saves the data for later (When it needs to send all the data to the
server). The container disables the current tab and enables the next
tab; It then sets the selected child to the next tab. I also have
Previous buttons to move to the previous tab.

This way, the user can only traverse the tabs as I want them to. They
can move back and forth between tabs and I validate the data each time
they press the Next button.

Usually when we do this, we use a view stack controlled by the next /
back buttons so it looks more like a traditional wizard. Why are you
using the tab navigator? It seems a little clunky.

My boss and the users like the way it looks. Unfortunately, I have to
do what they ask me to do.

I put together small examples of the different ways to do it and then
they pick the one they like (Even if it is a little clunky). Then I
complete the full functionality.

Don't you just hate users sometimes ;-}


 Why are you using the tab navigator? It seems a little clunky.

[flexcoders] Re: Traverse through a TabNavigator

2008-11-13 Thread Tim Hoff 

Since TabNavigator extends ViewStack, there's really no difference in
the approach.  One advantage of using a TabNavigator for something like
this, is that it shows the user where they are in process of completing
the wizard; similar to an Accordion.

I think my point was, it's a bit clunky trying to suborn the TabBar for
showing progress through a wizard, rather than rolling your own. Trying
to shoehorn the TabBar behaviour surely takes longer and will be more
buggy than making your own Wizard progress bar...

[flexcoders] Re: Traverse through a TabNavigator

2008-11-12 Thread Tim Hoff 

It's not bad per se, depending on the use case.   But, the navigator
containers only instantiate the first child, and then the other children
as needed (deferred instantiation); to cut down on the application load
time.  If your TabNavigator only has two children, you're not going to
see much of a difference.  And really, if you know that all of the forms
will be needed it's just a matter of preference; make the user wait at
the beginning or when a new child is needed.  However, deferred
instantiation is beneficial, if there are children that may never be
needed.
