var features = [];
features = new OpenLayers.Feature.Vector(new
OpenLayers.Geometry.Polygon());
you override the array with a single feature and addFeatures accepts
only array of features.
In my opinion your code should be like:
function cmd_MPoly_to_polys() {
var MPolyFeature = wfs_mpolygon.selectedFeatures;
var features = [];
var f = null;
var i = null;
for(var f in MPolyFeature[f]) {
for(var i in
MPolyFeature[f].geometry.components[i]) {
var_feature_ = new
OpenLayers.Feature.Vector(new OpenLayers.Geometry._MultiPolygon_());
var poly = new
OpenLayers.Geometry.Polygon(MPolyFeature[f].geometry.components[i]);
feature.geometry.components.push(poly);
feature.attributes.typ =
MPolyFeature[f].attributes.typ;
feature.attributes.tst =
MPolyFeature[f].attributes.tst;
feature.state = OpenLayers.State.INSERT;
features.push(feature);
}
}
wfs_polygon.addFeatures(features);
wfs_mpolygon.removeFeatures(MPolyFeature);
wfs_polygon.redraw();
}
for every component in every multi polygon you create an feature and add
it to the features array which you add to the layer later.

}
}
wfs_polygon.addFeatures(features);
wfs_mpolygon.removeFeatures(MPolyFeature);
wfs_polygon.redraw();
}
Seems like it creates no features on polygon-Layer.
