 Description   

Yang model like this:
grouping c-struct {
leaf lf

{ type string; }

}

container test-cs {
container test-c1

{ uses c-struct; }
}

rpc mergeC1 {
input { uses c-struct; }

}

rpc putC1 {
input

{ uses c-struct; }

}
------------------------------------------------------------------------------------
Register test-c1's changes, scope is BASE.

when use tx.put(store, path, t, createMissingParents), data change listener can get data chage event, otherwise use tx.merge(store, path, t, createMissingParents) can't. Test-c1's value in datastore are both changed using two method.

The reson is in Lithium, uses merge method to modify test-c1, test-c1.getModificationType() returns SUBTREE_MODIFIED. So the program continues to resolve test-c1's child lf. But lf has no listener, therfore can't get notification.
In Helium-SR3 instead, test-c1.getModificationType() returns MERGE.

DataChangeListeners have unfixable issues translating scope and are going away.
