I've developed a Silverlight web application for testing custom editing functionality and I am able to edit my feature service (which uses a feature class in PostgreSQL). However, for the life of me I can't get the default feature template to work on the feature layer. My feature layer is symbolized using a green outline symbol. When I begin drawing a new polygon it appears as a black outline but when the new polygon is completed it disappears--it doesn't have any symbology and it doesn't take the symbology of the feature layer unless I completely refresh the web app. Also, if I try adding a TemplatePicker control, the feature layer's template is blank. Any ideas on what i could be doing wrong? Thanks.
