RE: [flexcoders] Binding chart to XML

Wed, 21 Jun 2006 12:11:02 -0700

I wasn't deliberately using E4X (I don't really know what it is!!). I thought I was using XML! :-)
 
I added an @ and get the same issue:
 
"Property @val not found on flash.xml.XMLNode and there is no default value."
 
Any ideas?

In E4X parlance, attributes are referred to by prefixing their name with @.  i.e., to get the val of the first item in your code, you would write:
 
[EMAIL PROTECTED];
 
So to have a data component (chart, list, etc) pull a value from an attribute, you need to do the same:
 
<PieSeries field="@val" />

Subject: [flexcoders] Binding chart to XML

I'm trying to bind a chart to an XML document, like this:

/* Script */

var sXML:String = '\
<data>\
<item name="Aaa" val="6" />\
<item name="Bbb" val="46" />\
<item name="Ccc" val="16" />\
</data>\
';

gXMLDoc = mx.utils.XMLUtil.createXMLDocument(sXML);

pie.dataProvider = gXMLDoc.firstChild.childNodes;

/* End of Script */

And my series looks like this:

<mx:PieSeries labelPosition="callout" field="val">

But I keep getting the error: "Property val not found on
flash.xml.XMLNode and there is no default value".

What am I doing wrong?

Thanks
