So, instead of being asleep like an honest citizen at 2 o'clock in the morning, here I am trying to make hibernate save my collection of Strings.
(I would hate not to be a developer: who else deals with Collections of Strings, I wonder?)
The mapping is perfect, straight from the documentation, to tricky stuff, no funny cases:
<set name="categories" table="resources_categories"> <key column="resource"/> <element column="category" type="string"/> </set>
Except, when I populate my category list, and try
getSession().save(newResource) ... it doesn't save my Strings!
After a little more googling than I would have hoped, I bumped into this - http://forum.hibernate.org/viewtopic.php?t=951848&blah blah... where the hibernate team says you have to flush in this case. You don't have to flush to save most other things, but if it's a Collection of Strings, you have to flush.
So this works:
- no changes to the mapping required.
