[OpenLayers-Users] Drawing/modifying features in existing vector Layer

[Alexandre Dube]

Hi,

Here's an old demo doing that (with an outdated version of OpenLayers + 
TinyOWS) :
http://dev4.mapgears.com/bdga/bdgaWFS-T.html

Here's the same demo with Ext 2.2 (to use a Ext.form.FormPanel instead 
of plain html to render the form)
http://dev4.mapgears.com/bdga-mapfish/bdgaWFS-T.html

If you're using GeoExt, you could take a look at the FeatureEditorGrid 
ux widget (which could be combined to an existing vector layer instead 
of a blank one) :
http://trac.geoext.org/wiki/ux/FeatureEditing
http://dev.geoext.org/ux/geoext.ux/ux/FeatureEditing/examples/feature-editor-grid.html

Finally, I've been working on a WFS-T ux widget using the above 
FeatureEditorGrid ux (still in dev, in a sandbox). Its main purpose is 
to automatically build everything needed to do WFS-T editing (using WFS 
requests such as GetCapabilities and DescribeFeatureType) :
http://dev8.mapgears.com/geoext/mg-sandbox/geoext.ux/ux/WFSTFeatureEditing/examples/WFSTFeatureEditing.html
http://svn.geoext.org/sandbox/mapgears/geoext.ux/ux/WFSTFeatureEditing/

Best regards,

Alexandre
