Hello, I've been troubleshooting a pretty major memory leak in our application. I've narrowed it down to code which cleans up a chart's series array and re-initializes it to add a new set of series with new dataproviders, etc.
Note that with only the AddSeries, and SeriesDelete functions removed (all other code including CategoryAxis create/delete, and all XML manipulation remained) there was no leak. I posted a "best practices" question about list cleanup and memory use which describes the architecture I have: http://groups.yahoo.com/group/flexcoders/message/29638?threaded=1 Below is the implementation of DeleteSeries which attempts to remove every series in the chart and clean up the dataProvider in it. Can someone who knows the internal workings of the charts maybe look at this and see if I'm missing something or if there are any known issues with the cleanup of chart series? thanks, Thunder __________________________________ public static function SeriesDelete( thisChart:ChartBase ) { // try to clean up the series by deleting them from the array using splice var i:Number = thisChart.series.length; while(i--) { var obj:Array = thisChart.series.splice(i, 1); var oSeries:Series = null; if (obj[0] is Series) { oSeries = Series(obj[0]); if (oSeries.dataProvider is ListCollectionView) { var oView:ListCollectionView = ListCollectionView(oSeries.dataProvider); oView.removeAll(); if (oView.list != null) oView.list.removeAll(); oView.release(); delete oView.list; oView=null; } delete oSeries.dataProvider; oSeries.dataProvider=null; delete oSeries; oSeries=null; } obj=null; } thisChart.series = new Array(); } -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!
