Patrick, If I had a task to create a DataGrid with the ability to edit and save changes, then I would start something like this. I can change Incident number and track changes. I know, how to apply edits. Source is here (4KB). ... View more

Hi, Have you tried something like Clustering? I'm not sure, but maybe it will help. Also FeatureLayer has public property selectedFeatures = Array of Graphics in the current selection of this feature layer. It's readonly. This gives you the opportunity to make a new selection request with the choice of advanced query options. For example: (1) on client map click -> (2) new selection query based on geometry -> (3) as a result featureLayer.selectedFeatures -> (4) find needed feature in this Array -> (5) new selection query based on feature id. Maybe some of the steps are not needed. But the idea that all objects in FeatureLayer are the result of query from the server. ... View more

1 - when i import mx.controls.Alert; it says the import Alert could not be found Try it : www.adobe.com... 2 - is it possible to label the feature layer (in the mxml) without performing a query? I think: Yes. I have not found any query maker/caller in this sample. ... View more
