Hello!
I'm developing a Qooxdoo-Desktop-Application, which does periodically asking
the server about the current status (a timer elapsing every second), the
communication is done simply with a Xhr-Request (Code is below)
Everything is working fine on Windows 7 or 8
But on Windows XP (tested with Firefox and Chrome), the Browser uses more
and more RAM (150 MB per hour) until no free RAM is available
How can I manage this problem? Where and how do I have to free up memory?
I tried out a model.dispose()
Also I tried it with
this.storeStatus = new qx.data.store.Json( url );
and
this.storeStatus.reload();
I'm currently using Qooxdoo 2.0.1, but also tried it with 3.0 - no success
Thank you for your help!
Regards,
Hans Juergen Gamauf
-------------------------- sample code
if ( this.__statusReq == null )
{
var req = new qx.io.request.Xhr();
this.__statusReq = req;
req.setUrl( "/status/general" );
req.setMethod( "PUT" );
req.addListener( "success", function ( e )
{
var model = qx.data.marshal.Json.createModel(
qx.lang.Json.parse( this.__statusReq.getResponse() ) );
this.debug( "new update: " + model );
model.dispose(); //what about this?
}, this );
}
this.__statusReq.send();
