Webmaster Forum / Flash / Data Integration / February 2005

Hi Everyone,
    I've got a problem that?s driving me crazy.  I've built an application
with a preloader, knowing that I cannot use any class that has to be exported
to the 1st frame, and I have in fact set export to frame 5.  What I am trying
to do is load a second file containing my dataGrid, XML connector, and
dataBinding classes through the Loader component (using the Data Connection
Wizard).  To pass the needed URL to the second movie I am using a combination
of 2 global variables, 1 for the php folder location and 1 for the actual file
used to retrieve the dynamic XML file.  

Results:
If I run it and assign the URL to the XML connecter like the below 2 examples
it works fine.

  in the child swf
          this.myReceiveXMLConnector.URL =
"http://www.mysite.com/php/myXMLfile.php4?listType=All";
          this.myReceiveXMLConnector.URL.trigger();

          stop();

   OR

   in the parent swf:
         _global.phpListFile =
"http://www.mysite.com/php/myXMLfile.php4?listType=All";

   and in the child swf:
        this.myReceiveXMLConnector.URL = _global.phpListFile;
        this.myReceiveXMLConnector.URL.trigger();
       
        stop();

    If I try to build the URL dynamically and pass it through a global
variable like below, it no longer shows the data in the dataGrid that is
loaded, though the rows show up telling me that something has arrived. I have
tried passing different variables to this and I always get the correct number
of rows in the dataGrid, there is just no text displayed.

     on parent swf:
          _global.phpFolder =  "http://www.mysite.com/php/";
          _global.phpListFile = "myXMLfile.php4?listType=All";

    on child swf, frame 1:
          this.myReceiveXMLConnector.URL =
_global.phpFolder+_global.phpListFile;
          this.myReceiveXMLConnector.URL.trigger();
          trace(this.myReceiveXMLConnector.URL);    //this always shows the
correct URL with variables as expected
          trace(myDataGrid.selectedItem.columnId);   //this displays undefined
as if there is no data

          stop();

Running a trace on the URL always returns the correct URL with the correct
variables.  Running a trace on the selectedItem.columnId always yields an
"undefined" result.  

    Basically I know this, my XML output is fine and is loadable.  The child
swf when given a normal URL works fine, but when piecing the URL together with
variables no longer displays any data.

    What really gets me is I just did this same exact thing less then a week
ago with no problems what so ever.  I have reviewed my previous file and gone
over it with a fine tooth comb only to find nothing different.  Is there a
possibility of corruption in Flash that is causing this?  I?m willing to pass
these files onto anyone who might be willing to take a closer look at it.  I
have spent over a day on this one thing and I feel like I have no way to turn.  
I hope I have made this clear enough for someone to help me, I'm at my wits end
with Flash about now and I would sure appreciate any help someone could give.
