I try to persist nested records with jpa datasources, but getting warning "Can't convert value of type java.lang.Long to target type". It seems it doesen't understand the ManyToOne field when it is in a nested record.
In the sample code, when you press The Insert button, the Order will be persisted but the OrderItem not. (If I remove completly the 'product' field from OrderItem and from datasource, the Orderitem persisted correctly.)

Test code
In the product table there must be a row with primary key '1'.
