Hi all,

I want to develop a NAV file.
I start to loop through the _host.collection.items just after the GUI is initialized and _host is not null.
So far so good.
BUT:
if the item in _host.collection.items is a folder. I want to count the number of children. It is not working: item.children.length is always 0 at the moment.

Any one have any idea?: Lazy loading??? Bug???
And how to solve it?

@MODs: If it is not the correct place for this topic, please move it to the correct place.

Thank you for any help.

My Product Information:
Acrobat Pro Extended 9.3.1, Windows

You may need to set the 'disclosed' property of each pdf to 'true'

You can find more about creating a NAV file for portfolios at [url=http://joelgeraci.com/adobe/devjunkie/web/]The "Customizing PDF Portfolio Layouts" Series[/url] By Joel Geraci.

I read already the whole series.

This code is just after the GUI is initialized and _host is not null.

if(_host!=null && _TreeInitialized)
{
for each (var item: IAttachment in _host.collection.items)
{
if (item.isFolder){
Alert.show(item.children.length); //--- always 0
}


}
}


About "You may need to set the 'disclosed' property of each pdf to 'true'", i do not really understand.

Thank you for your help.

That is a document property introduced in version 5 of Acrobat and if that PDF property is not 'true' another PDF can not use JavaScript to access that PDF.

Have you tried posting to that blog or sending Joe an email?

A snippet of code from an object that contains many functions is very hard to debug.

Are you sure the the folder has children?

You might want to add more code that shows you more information about what you have.

I want do develop a NAV file with flex, not javascript. So i think that property is not important here.
I do not have much code, i just make sure that GUI is initialized and _host is not null. and then this code snippet.
And, yes, i am sure that the folder has children.

And if i switch to the list view and then come back to the home view (my nav file), then it show the correct value of item.children.length. It is really strange, right?

I do not have the email address of Joe. Do you have?

I suspect it's lazy loading. Try setting the current folder to that folder and then getting the children.

Hello Joel,

I change according to your suggestion, and it still not works.

<?xml version="1.0" encoding="utf-8"?>

Hello Joel,
Is there now a solution for this problem?
I wrote to you an E-Mail on July, 12 because you wanted to take that point out of the forum, but I have not received a response until today.

Thank you for your help
