Using httpservice in Flex/Actionscripts passing XML file with only one item

Jul 042010

I encountered a problem with passing xml file to Flex using Httpservice.
If the XML file I pass to the flex has only one item, e.g.:

<DATA>

<SoftwareName>Photoshop </SoftwareName>

</DATA>

Then if you use an arraycollection to save the data.

e.g.

[Bindable]

public var SoftwareData:ArrayCollection;

[Bindable] public var SoftwareData:ArrayCollection;

<s:HTTPService id=”getSoftware” url=”{SoftwareServer}” result=”getSoftware_resultHandler(event)” fault=”getSoftware_faultHandler(event)” />

if we use “SoftwareData=getSoftware.lastResult.DATA.Software; “, it will not work for only one item.

The solution is :

if(getSoftware.lastResult.DATA.Software==null)

{ Alert.show(“No record”); }

else if(getSoftware.lastResult.DATA.Software is ObjectProxy)

{ SoftwareData=new ArrayCollection([getSoftware.lastResult.DATA.Software]); }

else{SoftwareData=getSoftware.lastResult.DATA.Software as ArrayCollection; }
