[Mapbender-dev] concurrent editing

Hi All,

I've tried concurrent editing via WFS-T one polygon layer. Scenario
(timing via phone):
A selects a feature
B selects the same feature
A clicks a node and drags it
B clicks another node and drags it
A saves, response dialog box says success
B saves, response dialog box says success
result after resfresh is only B's edit. This means, that MapBender
holds the whole geometry info during editing, and commits it. However,
B's modification overwrites A's.

Is there a mechanism to avoid this problem?

I've read about WFS operations Lock and GetFeatureWithLock. Are they
used, to solve this question, or if not, is there a plan to use them?

best regards: Balázs Bámer
