Subject: [flexcoders] Supply list with XML fails when only one element
I have some simple XML which when passed to a control is displayed no
problems but when the XML only has 1 element it seems to fail.
The error I get is shown below as are my files just in case some one
has a chance to test it out.
I have a few books on Flex and they don't seem to use examples where
there is a piece of XML with just one child node, any ideas why this
error might be occuring?
TypeError: Error #1034: Type Coercion failed: cannot convert
mx.utils::[EMAIL PROTECTED] to mx.collections.ArrayCollection.
