Frankly I think you’re getting lucky
that the direct XML works. The DataGrid can’t handle the XML object
because the properties and such don’t present themselves cleanly (you
have to access childNodes, nodeName, nodeValue, etc). That’s why
HTTPService defaults to de-serialize into an object structure. Matt From: Tracy Spratt
[mailto:[EMAIL PROTECTED] There
are a few other threads about this, and I have never been comfortable with
mx:Model so I decided to try to figure it out, but have been
unsuccessful. In the small sample app below, I have three
datagrids. One uses XML directly, one uses a mx:Model populated
statically, and one uses a Model populated by binding the XML. The
direct XML and static model work but I must be missing something basic in the
bound model: the DataGrid remains “desperately”
empty. Does anyone see the problem? TIA, <?xml
