How to access an array in one class from another
This is a Flash 8 AS2 question
Attached is testimonials.fla. Testimonials imports a class XML_ArrayForLoop which loads external XML data and stores it in two arrays, level01Array & level02Array. The arrays are populated and verified within XML_ArrayForLoop.
The question is how do I access the arrays from within testimonials.fla?

Juliano,
I think you are right about trying to access the arrays before they are completely loaded. I know they are correctly loaded in XML_ArrayForLoop. XML_ArrayForLoop is initiated from within the fla file and in the nest line of code the fla file tries to manipulate the arrays. What seems to be needed is a way of only executing the follow-on fla actions once the arrays have completely loaded; e.g., a listener or if status=0 condition.
Here's the general idea. I have 3 Flash modules that work together.
Base class: (XMLLoader.as) which holds all the basic code
Parsing class: (XML_ArrayForLoop.as) that would be called by XMLLoader to supply a specific routine. This would be selected from a library of standard routines - load into array of strings, load into an array of objects, namespaces and so on.
An Fla File: (testimonials.fla) that would call the correct parsing class to launch the XML loading. On a project basis I would only have to decide the parsing method and input project specific info; eg.; path to XML file.
Currently, everything works and the XML successfully loads into 2 arrays (one for each level in the XML file) The problem is the arrays are living in the XML_ArrayForLoop.as file and I'm stumped about how to access them from within the fla file, which is needed to process them into the final product - navigation scheme, page structure, or in this case a list of testimonials and authors.
As you can probably tell I'm pretty new at AS and definitely new about how to use this forum. I couldn't find a direct link to you, so I have attached the three AS files as 'snippets". Hopefully they will make it through. I appreciate your help. I can be reached at doug@pricelearman.com.

OK. Here it goes. I created an event handler inside the XML_ForLoopArray , that gets called whenever the load process ends, take a look at the code we call onLoad(), wich in turn is declared as a function on the class itself, it is empty cause it is meant to be overriden, AS 2 style. Then take a look at the end of the testmonial AS i put there, we wait for the onLoad to fill the arrays.
note: I haven't tested cause i don't have the .fla, but I'm sure it will work. I just copied your code to notepad, edited, and paste back, so hope everything else is intact.

UPDATE: Above as the code snippet section has line numbers, I'll write here the lines where you should look :
Line 345 - Call the event to notify - event dispatching
Line 352 - handler place holder
Line 435 - 443 - use the xml onload to wait for the result
Just keep in mind what I told you. Every external communication from flash is not synchronous, so you always need to use a event listener or some kind of event to respond the completion of the async process.

I'm not sure how your theXML.onLoad function relates to the theXML.onload on line 146. Do we need both? I still get undefined for the quote & author arrays. I have attached a piece of the XML file if you want to test. Thanks

I'll test for you
I found the problem. As I did not test and have not looked through your code, have not seen that your properties level01Array and so on, were private, so it was not possible to access those outside the class. get my attached file to see it working. In my example I extracted the packge information of your classes, so I did not have to create folders. ;)

Ok. I have posted another question here. I also emailed you at digitalbug. I have a small media company in Seattle area. I see Flash as the future for design driven sites for a host of reasons. So, I made the 'executive' decision to develop all future sites in Flash. As a result, I'm learning AS 2 on the fly while doing live projects. A bit steeper curve than I anticipated, and I could use professional services on problem-by-problem basis.
I'm in brazil. Here I'm a consultant and adobe certified instructor. I also have a small company for web development. anytime you need send me email and we can talk about that partnership.
so send me the code.
But anyway from what I see, the problem is that you are trying to acess the xml data before it is available. Everytime you request external data from flash , it comes asynchronously. So when you call doXML, there is no way it will retrieve information before the folowing lines are executed. So theXML.array01 and theXML.array02 will not have any data inside them. You should have a listener function in your new XML_ArrayForLoop(); class, like a onLoad, so you know when it happens. The final code should like like this:
var theXML:XML_ArrayForLoop = new XML_ArrayForLoop();
var myFile:String = "__xml/testimonials.xml";
var proxy:Boolean = false;
theXML.doXML(myFile, proxy);
// variable to hold created arrays
//
var quotes:Array;
var authors:Array;
thisObj = this;
theXML.onLoad = function(){
thisObj.quotes= this.array01;
thisObj.authors= this.array02;
}
As I don't know that class of yours I don't know what is really happening.
