Hi,
Something is funny here because the mapEditor shouldn't have to be
open for the layer to have a map. Indeed as soon as the layer is
added to the map it has a map. I'll admit that there is some
dependencies. For example a layer isn't usable without a map. There
is a construct called Layer interceptors that run when a layer is
created but I don't see how that could cause a problem...
Are you sure that you are not editing a layer before adding it to a map?

After switching to SDK 1.1RC10 I got an odd nullpointer exception
at removing features of a feature store.
I use a temporary / memory based layer which is wrapped by a class
called LayerContainer. This class has some convenience methods for
changing the (SLD) style and for adding / removing objects like
this one:
private void removeAllContent(){
FeatureStore fs = layer.getGeoRessource().resolve
(FeatureStore.class,null);
fs.removeFeaures(Filter.NONE);
}
Using SDK1.1RC8 the object "fs" is an AbstractFeatureStore. Using
SDK1.1RC10 it is an UDIGFeatureStore which calls the method
"setTransactionInternal" in every method which changes the set of
features. In setTransactionInternal this line fails in my application:
Transaction transaction = ((EditManager)) layer.getMap
().getEditManager()).getTransaction();
layer.getMap() returns null
getMap() invokes getMapInternal() invokes getContextModel() which
returns the eContainer (type: InternalObject) which is null
I can only guess what happens: The the layer is manipulated
(adding / removing features) before the map is opened in a
MapEditor the first time. This is done since the user can "add
objects to map" in a perspective which has no visible map / no
MapEditor. The class LayerContainer is notified via eventmanagement
and adds / removes features. Under 1.1RC8 this doesn't matter since
another FeatureStore is used.
(The map object is created before the layer is instanced.)
what can I do?
