RE: [Junk E-Mail - LOW] [flexcoders] Re: Noob binding question

The problem is I'm trying to get data from a query returned by a CFC into a datagrid. Before, I was having problems getting data back.
 
Now I've got the data back, and it won't display (I was getting an empty datagrid). So, I removed my user-defined columns, to see what was coming back, and the result is:
 
FilterFunction, length, list, sort, source
 
Those are not the columns of the query... I'm guessing they're properties of the ArrayCollection, or maybe even the datagrid itself.

“When I remove my columns from the datagrid, the datagrid shows these columns from the dataprovider:”  I do not understand this.  Did I miss something in a previous post?  Can you re-phrase the problem?

I did the changes you suggested, and I can successfully make the request and get the response back.

Unfortunately, it looks like there's something wrong with my ArrayCollection.... When I remove my columns from the datagrid, the datagrid shows these columns from the dataprovider:

FilterFunction, length, list, sort, source

*now* what'd I do wrong? :)

Hi Shannon,

Here's a couple things that might get you moving forward.

First, add a fault handler to your RPC, to see if the CFC result is getting through:

fault="Alert.show(event.fault.faultstring, 'Error');"

And, some subtle changes to your functions:

private function appInit():void
{
                cfcServer.getServerInfo.send();
                cfcServer.getServerLoad.send();
}

function serverInfoResult(event:ResultEvent):void
{
                var serverInfoDataArray : Array = mx.utils.ArrayUtil.toArray(event.result);
                serverInfoData = new ArrayCollection(serverInfoDataArray);
}

Finally, check to see if the fields that you are binding to the DataGrid columns are syntactically the same as the CFC query.  Someone earlier suggested using all CAPS for the field names.  But, I was under the impression that they were case-sensitive.

Besides that, It looks like it should work.  Good luck.
