> Merge operation in camel-olingo2 sets all entity properties to null
> -------------------------------------------------------------------

> Key: CAMEL-15407
> URL: https://issues.apache.org/jira/browse/CAMEL-15407
> Project: Camel
> Issue Type: Bug
> Components: camel-olingo2
> Affects Versions: 3.x
> Reporter: Christoph Deppisch
> Priority: Major
>
> The merge operation in OData V2 can be used to update individual fields on an
> entity. The operation should perform an incremental update without replacing
> all the contents of an entry. In particular the request updates only the
> properties indicated in the request body, and leaves untouched any other
> property not mentioned in its current state.
> When the camel-olingo2 component performs the merge operation all fields are
> updated - also the not mentioned properties. Those fields not mentioned in
> the request body are set to null by default.
> This behavior is controlled by the EntityProvider write property called
> "isDataBasedPropertySerialization". By default this setting is set to false
> resulting in non present fields to be set to null by default. For merge
> operations this setting should be enabled by default in order to just update
> the mentioned fields in the request body.
