I have some WFS layers in OpenLayers, containing Polygons. I try to make a tool to split these polygnos and save them to db.

//The layer which I want spliting work on
var contract_layer = map.getLayersByName("contracts");
//The spliting control
var split_control = new OpenLayers.Control.Split({
       layer: contract_layer,
       listeners: {
           'beforesplit' : function(){

and then I add this control to my map and make it active:

toolbarItems.push(new GeoExt.Action({
       control: split_control,
       map: map,
       toggleGroup: 'map'


And now when I chose the tool, I can draw a line which ends with double-click, but that's it. nothing else.Nothing splits and nothing is sent to geoserver. What do you think I'm missing?

I think the split control only works against line features, not polygon features. You will need to post the feature (to be split) and split line to a Web Processing Service, or use the jsts library.
