Yes I have WMS layers (correspond with the nodes). Till now a GFI request is sent when a user click on a feature. But I want to load all features of the selected layer into the store btw showing this store (without a user click but with changing the selected layer node). >I guess you could have each layer keep a reference to the corresponding store. With adding my layer to stores configuration? But I would perhaps think that loading all layer stores (having 8 WMS layers) is a bit time consuming for my app (one layer store takes about 3sec but I think my server configuration is not oiptimized yet). So defining schema like you said before is perhaps a better choice? Thanks again. best regards Sarah ________________________________ On Wednesday, June 16, 2010, Sarah Schuessler <[email protected]> wrote: > Hi Eric an dlist, Hi Sarah > > thanks for your feedback. > I´m already have a function getAttributes(node) which makes a Getfeatureinfo > request (having WMS layers) depending on node.layer.params.LAYERS on users > click. > My store is defined like: > var attributeStore = new GeoExt.data.FeatureStore({ > fields: [{name: ......, type: 'string'}, {...}], > proxy: new GeoExt.data.ProtocolProxy[{ > protocol: new OpenLayers.Protocol.WFS({ > url: "http://xxx/geoserver/wfs";, > featureNS: "xxx" > ... > schema: > "http://xxx/geoserver/wfs/DescribeFeatureType?version=1.1.0&typename..."; > }) > }), > autoLoad: true > }); > > I want to know if the layer (node) has knowledge about the preconfigured > store (so I can use somethink like node.layer.store). So if I understand correctly you have WMS layers in the map, with corresponding layer nodes in a tree. When a layer node is selected (w/ a radio button) WMS GFI requests can be sent (on click I guess). And you'd like that results of GFI requests be added to a (pre-configured) store somehow bound to the WMS layer. Right? I guess you could have each layer keep a reference to the corresponding store. Also, why do you have a ProtocolProxy (with a WFS protocol) in your store? If you use WMS GFI requests then you don't need that ProtocolProxy. > Or is this method more difficult than your approach with WFS?

Well I think you can forget about that, as I haden't understood you when I wrote this. I thought you were looking at knowing where to define your layer shemas, and I was telling you about the options you had for that. I hope I do understand you now. -- Eric Lemoine Camptocamp France SAS Savoie Technolac, BP 352 73377 Le Bourget du Lac, Cedex Tel : 00 33 4 79 44 44 96 Mail : [email protected] http://www.camptocamp.com
