I found my fault of the first try:
instead of using
layer.getGeoResource().resolve(FeatureStore.class,null);
you have to use the FeatureSource
layer.getGeoResource().resolve(FeatureSource.class,null);
which returns an object which has the added features.

You are correct. You need a behaviour that will change the current state (on the ToolHandler if I remember correctly) from create to NONE or MODIFY? Or something like that. I beleive that is what terminates the editing.

If I override the initAcceptBehaviour() method (addAcceptBehaviour doesn't exist) with an empty method, it isn't possible to finish drawing since the double click is not recognized / accepted. ... I'll play with that, perhaps I find a solution.
thanks for your hint

I don't see anything obvious I'm afraid. I could suggest another way
of doing this though. You could make a new Tool that extends the
PolygonTool and overrides the addAcceptBehaviours() method. The
overridden method would add a new behaviour which could either add
the created polygon to the Layer's black board (or just do nothing).
Then your search method could use the shape on the layer's blackboard
(you wouldn't need a dedicated layer for this) to construct the
search query. If you did not add any new behaviour (just overrode
the addAcceptBehaviours method with an empty method) then you could
use the shape on the EditBlackboard to construct your query. To get
the correct blackboard do: EditblackboardUtils.getEditBlackboard
( ApplicationGIS.createContext(layer.getMap), layer ).
