[OpenLayers-Users] How to insert that I digitized Feture in my WFS layer?

[polock]

Again and again I receive the error message from the firebug:
An attempt was made to create or change an object in a way which is
incorrect with regard to namespaces" code: "14

var wfsl= new OpenLayers.Layer.WFS( "MY WFS", 
                                           
"http://localhost/geoserver/wfs?", 
                                            {typename: 'topp:mywfs'}, 
                                                       { typename: 
'topp:mywfs'  }); 
wfsl.addFeatures([feature]);
wfsl.commit();

Wherein am I mistaken?
