Undocumented XMLUtil class in Adobe Flash CS5?

I tried to recompile an older Flash CS 4 project with Flash CS 5 but got this compile time error 1061: Call to a possibly undefined method reuseNodes through a reference with static type Class caused by the usage of one of my utility classes:

This didn’t work

import de.superclass.util.XMLUtil;

This still works


So there was no error in my class because it’s still usable when I use the full class package but it didn’t work when I just import it with the import statement.

After some research I found an undocumented XMLUtil class which avoids the correct access to my de.superclass.util.XMLUtil class.

This class doesn’t exist in Flash CS 4 but is available in Flash CS 5. Simply create a new FLA in Flash CS 5 an run this code on timeline

trace( describeType( XMLUtil ) );

and you’ll get this result:

So I had to rename my class to de.superclass.util.XMLUtils.

You might run into the same problems when using mx.utils.XMLUtil (Flex Framework) or com.adobe.utils.XMLUtil (AS3CoreLib) but I didn’t test it!

I found XMLUtil classes in
Adobe Flash CS5/Common/Configuration/ActionScript 3.0/libs/ik.swc and
Adobe Flash CS5/Common/Configuration/ActionScript 3.0/libs/PffLib.swc

Removing the $(AppConfig)/ActionScript 3.0/libs directory within the ActionScript export settings avoids the problem. But I have no time to test if this directory is necessary. If you run into problems please leave me a comment!

  1. Thank you for clarifying this. I have a custom XMLUtil Class that I was using in CS4. When I ported my code to CS5, I got an error 1061. Now I know why! Thanks again for your assistance.

  2. Thanks for posting this. I inherited a CS4 file and couldn’t get it to compile inCS5. Turns out it was importing com.adobe.utils.XMLUtil from AS3CoreLib.

    I renamed XMLUtil and changed all the imports and definitions, and everything worked fine.
