Issues with displaying retrived database content

Question

First off, hello everyone.
Secondly I've got an issue that I've been struggling with now for a while. I'm trying to tie data from a MySQL database, through the use of PHP classes, to my Flex project.
I've gone through the initial PHP'ing and that now works like a charm (returning values in an object).
The problem I have is that when I try to assign a value from the retrieved data to an object in my flex project (for example a label (labelID.text = retrivedData) it wont work. I've looked at the tutorial videos, and tried to use the same methods as shown (or as near to them as possible).
Essentially what I'm trying to do is have a combo box fill with data collected through the creationComplete method (works fine). I then want to have a onChange event that calls a custom function that, with the selected item's data value (ie not selectedIndex, but in my case selectedItem.type), does another call to the PHP class. I then want this new information populating the .text, .source, .label value of a number of items in my flex project. None of this works.
Preferably I would also want to be able (within the custom AS function) to call another function in my PHP class to retrive yet another array of data. This would then populate the next Combo Box.
I really hope this got confusing enough .
Please keep in mind that I am very new to the whole world of Flex, so be gentle.
EDIT: I got was able to populate the label I mentioned, but only by using text="{fetchNameResult.lastResult[0].Name}". Only fetchNameResult.lastResult.Name wont work.

Answer 1

Yes I see your point. Then my conclusion would be that putting the line typeName.text = fetchNameResult.lastResult[0].Name; inside the custom function changeName() would solve the problem, but after trying it I can say it doesn't.
Could it be an issue where the line to set the typeName.text value is executed before the async result from fetchNameResult has been populated and returned from the SuperController.as file? Since if I just try it with typeName.text = "test", it shows up fine in the application when calling the function.
This issue is really doing my head in, and any help solving it would make my week
