GPMONGODB-93: Setting WriteConcern in mappings section of a domain class has no effect

Original Reporter: emedina
Environment: Not Specified
Version: 1.0.0.M7
Migrated From: http://jira.grails.org/browse/GPMONGODB-93

According to the documentation, you can force the WriteConcern based on specific domain classes. For instance:

class A {
static mapWith = 'mongo'

ObjectId id

String name

static mapping = {
    writeConcern WriteConcern.FSYNC_SAFE
}

}

However, this has no effect when saving/updating the domain class instances, as if it's completely ignored.

For example, if I try to save an instance of class A, MongoDB displays the following output in console:

Mon Aug 22 10:38:28 [conn281] insert test.a 0ms

As you can see, there's not reference to getLastError() whatsoever, and I would expect something like this:

query test.$cmd ntoreturn:1 command: { getlasterror: 1, w: 1, wtimeout: 0 } reslen:94 0ms

To execute the test case, just run the app and click on the AController. Then check MongoDB console output.

As far as I recall, this feature has never worked in any previous release...
