You have to set a map for that map to be populated.

If you have a model with IDs you shouldn't need to do anything, other
than set this map if you want mapped lookup...
/**
* Sets the map used to cache the EObject identified by the value
of its ID feature.
* This cache is only activated if the map is not <code>null</code>.
* The map will be lazily loaded by the {@link
#getEObjectByID(String) getEObjectByID} method.
* It is up to the client to clear the cache when it becomes invalid,
* e.g., when the ID of a previously mapped EObject is changed.
* @param intrinsicIDToEObjectMap the new map or <code>null</code>.
* @see #getIntrinsicIDToEObjectMap
*/
You should always be able to call Resource.getEObject with your ID and
expect the object with that ID to be returned...

The schema that I am using to generate my ecore model does not have any
xmi:ids declared.
