I made progress and now I'm able to copy between, but there is some strange
behavior. See below ...

i changed the copy action:
function copySelectedFeatures (layer){
features = select.features;
layerFeatures = layer.features;
var layerFeaturesLengthBegin = layerFeatures.length;
for (i=0;i<features.length;i++){
var geometry;
//check whether its multi or normal geom and copy the inner one
if (features[i].geometry.components != null){
geometry = features[i].geometry.components[0].clone();
} else {
geometry = features[i].geometry.clone();
}
var feature = new OpenLayers.Feature.Vector(geometry);
layer.addFeatures([feature]);
//this is a specific draw control for this layer
controls["draw_"+layer.name].featureAdded(feature);
}
}
this works well and i can copy all my geometries to another
vector(wfs)layer. The problem was that if my destination layer was one that
had a multigeom i tried to add a multigeom to it. For me that sounded to be
the right approach, but when I did so, the transaction only hat an empty
geometry.
Then i tried to copy a non multigeom to the corresponding multigeom
destination layer and it worked my transaction was complete with a full
geometry and I got the added feature in my destination layer.
For me this sounds a bit weird that I am not able to copy i.e. a
multipolygon to a multipolygon layer. Maybe my approach is in some way
wrong, but maybe it's a bug?
Greetings,
Fabian
