refreshing data

[maxkool]

Hello all,

All I would like to do is to refresh a xml model every 5 mins or so( since the
xml file will be updated every 5 mins or so as well) I have found some exampels
of how to do this but they where way overly complex for my simple needs. I know
to use set interval but I'm not sure how to use that in tandem with a data
service.

Thanks!

i know it is something very simple, but i'm racking my brains!!

thanks

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml" xmlns="*"
creationComplete="startApp()">

<mx:Model id="crimeModel2" source="data/ticker.xml"/>
<mx:Script>
<![CDATA[
function startApp()
{
setInterval(this,"getData",5000);
}
function getData() {

crimeModel2.item();

}
]]>
</mx:Script>
<mx:DataGrid id="output" dataProvider="{crimeModel2.item}">
</mx:DataGrid>
</mx:Application>

Hello,

I'm trying to overcome the same issue, only I need to do it with a xml model. Is that even possible?

Thanks

Are you certain that the XML file hasn't been cached? I bet it has. To see
this for sure, see what the HTTP status code is on the response from your
web server. I bet it's indicating that it has been cached.

Did you figure this out?

You will not be able to use source=, because that is a compile time
assignment. Instead, you need to use HTTPService.

You will call the service's send() method from your getData() function.
Either bind the model to the HTTPService result, or, as is my preference, use a
result handler and assign the result to whatever you want. This is easier to
debug than binding.

Getting data in Flex is, sadly, never very simple.

Hello,

Sorry it's talen me so long to get back to you. Yes, I did figure out the
whole refresh thing:

Here is a short example I didnt want to take up too much space on the forum:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"
marginTop="0"
marginBottom="0"
marginLeft="0"
marginRight="0"
height="100%" width="100%" xmlns:local="*"
initialize="myHTTPData.send();trace('calling service');"
backgroundColor="#cccccc"
creationComplete="startApp()">
<mx:HTTPService url="link to xml data source" id="myHTTPData" method="GET"
result="refreshdata">
</mx:HTTPService>
<mx:Script>
<!]>

</mx:Script>

i hope this helps other guys in the same boat i was in
