Please note that this demo uses the following unstable widget(s) : editfeature_delete, featurepanel_form.

Both widgets allow dragging a selected feature, but with one difference : the Drag widget modifies the original feature ('update' action) while the Copy widget makes a copy of it first ('create' action).

The dummy_poly resource has the 'copyFieldList' option set to "class,aaa,bbb", so only these attributes are copied (only class actually exists).
