JPAProducer Null-values for java.util.Date not working

What steps will reproduce the problem?
1. Create an entity with a temporal column, e.g.   
@Temporal(TemporalType.TIMESTAMP)
  @Column(name = "P_DELETED_AT")
  private Date              deletedAt;

2. Create a entity with a null value, either by code or SQL
3. Edit the entity using the odata layer leaving this field empty (null)

What is the expected output? What do you see instead?
My expectation is that the column will be null after the operation completes, 
instead it contains the current timestamp.
Reason for this is in OProperties.datetime(String name, Date value) 
which doesn't consider null values.

What version of the product are you using? On what operating system?
Version 0.5, OS: Windows XP SP3

Please provide any additional information below.
