injecteer opened a new issue, #14386:
URL: https://github.com/apache/grails-core/issues/14386
My domain classes are like:
```
@Entity
class Arbitrary {
String id
Map<String,Object> data
Geometry geometry
static embedded = [ 'data', 'geometry' ]
}
```
and
```
import grails.mongodb.geo.MultiPoint
@Entity
class Geometry {
MultiPoint points
}
```
Setting the `arbitrary.data = null` in controller works just fine, but
`arbitrary.geometry = null` is ignored.
In order to dance the problem around, I defined a fake constant and the
checker method in Geometry class, like so:
```
class Geometry {
...
static final KINDA_NULL = new Geometry( points:MultiPoint.valueOf( [ [ 0,
0 ] ] ) )
boolean kindaNull() {
points == KINDA_NULL.points
}
}
```
and added the interceptor into Arbitrary class like so:
```
class Arbitrary {
...
def afterUpdate() {
if( geometry.kindaNull() )
Arbitrary.collection.update( [ _id:getId() ], [ $unset:[ geometry:1 ]
] )
}
}
```
Then it works kinda as expected.
