Title: store can not be called here, because it clears object's data_map

For example we have a content class, which consist of following attributes:
- attribute 1 (any datatype)
...
- attribute 10 (any datatype)
- attribute 11 (objectrelation list datatype)
- attribute 12 (any datatype)
...
- attribute 20 (any datatype)

When new content object of this type is published (without any relations in attribute 11). It`s datatype cache will be cleared. And it will be not possible to get valid object`s datamap in attribute 12 ... attribute 20.

Current changes fixes this bug.
