Hi Andreas,
Thanks for the answer. I used only one layer with several rule based styles,
sorry for the bad wording. I copied the styles on the GUI, and when I checked
the xml file, most of the pasted entities had the same string in their key
field, which is the id, I guess.
Concerning the bug tracker: thanks for the explanation, I will try the mantra
thing.
Best regards,
Peter
