Hi Balázs,

thanks for your report and testing this behaviour.

Mapbender doesn't yet implement Lock or GetFeatureWithLock, but it would 
make sense, as your example above states. It should at least be a 
configurable option.

If you plan to do some work on this field, we should talk about it and 
discuss where to add the necessary code.
