[Xerte] Navigation blues

That helps me out.

And though I see content is killed, I don't get why I can't navigate back structurally. 

"when I try to navigate
back to FW2.page(1), debug says it is executing, but no navigation happens."

Will fwid.page() work from any level of nesting? (assuming of course it has been created)

Or does it require a more qualified path when it is not in the same vicinity/level/parent set/whatever.

The piece kicks up:

-         
Any top level page models are loaded;

-         
Styles are created from the LO icon, some other stuff like templateData

-         
The interface is created, or not,

-         
The first page is created, and all of it’s children are
added to it until it hits an interaction that it not perpetual; a framework , a
decision, or a sound set to wait; subsequent content is added as those icons
exit; any framework will have it’s first page created in the same way; interaction
responses are set up, but their children are not added until the response
matches;

-         
The top level pages are created – but none of their
children until the page is shown;

-         
Navigate to a new page kills all the existing content in the
current page – it is deleted (explains whey the page is set up like new
when you return to it;

Check out lines 500 – 650 on frame 2 of XMLEngine.swf. This
is the parser function, which is called everytime content needs to be setup –
there are some comment sin there,

Right on the head.

I'm still falling down on how the parsing proceeds then, and where/why parsing
pauses.

>From yourself in the archives:

As the rlo file is parsed, it does things in this order:

- Sets up the interface

- Creates the first page

- Adds its child icons and executes any script

- Adds the next page

So
I have

LO

  INT

    PG

and everything else is nested inside that first page.

So is this where I'm misunderstanding?:

When you say "Adds its child icons", you mean it adds it's direct
children, no more and no less, then the flow starts flowing and what happens is
what happens.

Once created, does it not persist?

e.g. Once I got to FW3.page(0) (using your instruction) when I try to navigate
back to FW2.page(1), debug says it is executing, but no navigation happens.

argg.

At that point FW3 does not
exist. You are in FW1 on PG1. You can call FW1.gotoPage(1) which will take you
where you want to go…?

No
matter how they are nested?

LO

 IFC

   PG

     FW1

       FW_ENT

       PG

         FW2

           PG

           PG

             INT

RES

SCR - want to nav from here. 

           PG

       PG

         FW3

           FW_ENT

           PG - to here

           PG

           PG

           PG  

FW3.gotoPage(0) doesn't seem to do it.

It works for me in the 2.6
desktop version. Note that the pages array from which the page number comes
from is zero-based, so myFrameworkId.gotoPage(4) will actually take you to the
5th page on the framework.

Found this in the archives:

"..but you could navigate to any page on any framework by using
myFrameworkId.gotoPage(pageNumber)."

Is it true?

It doesn't seem to want to work that way for me.
