GPMONGODB-23: Plugin fails with NullPointerExceptions

[graemerocher]

Original Reporter: nugsie
Environment: Grails 1.3.7, Ubuntu 10.10, Java 6 (OpenJDK)
Version: 1.0.0-M5
Migrated From: http://jira.grails.org/browse/GPMONGODB-23

Looks as if:

final MongoTemplate template = mongoSession.getMongoTemplate(entity); [MongoQuery line 338]
is returning null as a result of an empty mongoTemplates Map in MongoDatastore.

1. Create a basic project, single entity with controller and views.
2. Fire up with 'run-app'
3. Attempt to view list/create pages -> fail with NPE

NOTE: The same applies for all CRUD operations, dynamic finders etc. though obviously with slightly varying stack traces.
