I've used the WMSGetFeatureInfo control to populate WFS fid filter( s) several times and it works quite well to have that bridge. I think this would be an extremely valuable UX widget to have. Thanks for your work that continues to push the GeoExt platform further.

Basically, it would be configured with a list of WFS server urls and automatically create Vector layers using WFSGetCapabilities and WFSDescribeFeatureType requests. The widget would take the form of 2 buttons that, on click, list the layers (layer names) in a menu. One is for "Draw", the other for "Edit". * Draw : when a layer is selected in the menu, simply activate the DrawFeature control and displays the Vector layer. When drawing is complete, activates the "Edit" tool... * Edit : when a layer is selected in that menu, activate a SelectFeature control and automatically displays the Vector layer. When a feature is selected (by click), a FeatureEditorGrid widget is created using a DescribeFeatureType request and its ModifyFeature control is activated as well, thus allowing attribute and geometry editing. It is shown in a Ext.Window (or Ext.Popup). == Next "add-on" to add to this widget == A "WMS" feature selector. It is a common issue to have to display too much vector features on the map at once in order to interact with them. This add-on would basically try to fix that by replacing the SelectFeature control as the way to select features by a WMS GetFeatureInfo control. The vector layer would be created with Filter that always returns blank (nothing). Using the WMS query tool, a click on a WMS feature would return one or more ids of features, then one could be selected and added to the Filter in order to draw it. Upon draw completed, select the feature shown that would activate the FeatureEditorGrid widget. This would require to have WMS layers in the application to talk to the WFS layers... Comments are welcomed. == Other details == * layers created will have "displayInLayerSwitcher": false * their visibility would be automatically managed by the editing tools * FeatureEditorGrid would appear in a Ext.Window or GeoExt.Popup. I'd like the popup to be automatically displayed in the opposite direction of the feature centroid. If the feature is more in the upper left portion of the map, display the popup in bottom right. We could make these upgrades in GeoExt.Popup. * The FeatureEditorGrid would be translated in French, using the Ext.apply method to override the text properties. * The DrawFeature control handler would be automatically set to the according 'geometryType' of the layer using "DescribeFeatureType" request. (now supported in TinyOWS) * If a WMS layer with the same name exists in the application, it would be automatically refreshed upon commits. * GeoExt.data.WFSCapabilitiesReader : would need to have the change to allow layer protocol definition (rather than hardcoding them)... == A name == I'm terrible at this task... and it's always a pain to change it afterward. How about GeoExt.ux.WFSFeatureEditingWizard ? I dunno... ;) I guess this is the task I required the much more help. == Comments ? == If anyone has any comments, suggestions, questions, don't hesitate. One thing certain, I'll begin to work on such a tool in the following weeks, but I'd like to know if it would be nice to have it in more than a sandbox. About that, I'll be working next week on my WMSBrowser and LayerTreeBuilder widgets in the OSGeo code-sprint in Montreal and try to do what's required to make them official GeoExt.ux.
