LR7 and SB convert-null
New Member Beiträge: 18 Beitrittsdatum: 26.03.17 Neueste Beiträge
Hi everybody,
i've a foreign key (int) and i want to save it as null by service builder when not initialized (0-value).
In service.xml i use
but i receive a "Cannot add or update a child row: a foreign key constraint fails" on the CCLI_IDFK field (is a mysql nullable field).
the "convert-null" property is active in LR7? alternatives? i've try also with true but it doesn't go.
For the moment i disabled the foreign key but isn't a great solution
Thank you to everybody!

Hi pleo84,
I checked the DTD from the source, and it looks like it is still supported in 7. I can see in the DTD a comment explaining a bit about it as well --
-- are you experiencing and error when you run the "build-service" target/task? A runtime error? or ... it's just not doing what you expect?

The convert-null value specifies whether or not the column value is
automatically converted to a non null value if it is null. This only applies if
the type value is String. This is particularly useful if your entity is
referencing a read only table or a database view so that Hibernate does not try
to issue unnecessary updates. The default value is true.

Hi Andrew,
many thanks for yout support and sorry for the delay.
You're right: i applied the features to int field but, as you said, the feature work only for String field.
I resolved using String in table and with some dirty code for manage it.
Many thanks again and happy coding!
