XMLListCollection:
<mx:XMLListCollection id="delays_xml"
source="{getadvisordelays.result.*}" filterFunction="filterData"/>
where getadvisordelays is an HTTPService call to a jsp, returning
results in an e4x format:
<mx:HTTPService id="getadvisordelays" url=""
method="GET" showBusyCursor="true" resultFormat="e4x">
I'm wanting the ability for the user to sort columns when they click
on the column header. Do I apply the sort as part of the
XMLListCollection via the "sort" attrib, or via a
sortCompareFunction on the individual dataGridColumns?
I made an initial try of adding a custom compare function as part of
the dataGridColumn, but I get an error of "expecting 3 args, but
could 2" when I click on the column header:
<mx:DataGridColumn id="col1" resizable="false" textAlign="center"
fontWeight="bold" headerText="STA" width="{dgDelays.width/22}"
headerWordWrap="on" dataField="acfrmsta"
labelFunction="labelFunction" sortCompareFunction="sortAlpha"/>
my sortAlpha function prototype is:
public function sortAlpha
(a:Object,b:Object,index:Number):Number
I couldn't see why it was passing just two args, so I started
investigating sorting on the XMLListCollection instead.
any suggestions?
