Hi all
I could be missing something simple, but the mapping files below do
not give the expected results - or results as I would have expected
them to be more accurate. I could be attempting something that is not
possible
Basically the data structure is as follows
Files -> many FileLifecycles -> each lifecycle can have a FileStatus
(legacy db explains the composite keys).
I had thought that by setting insert="false" update="false" on the
many-to-one collection of File Status (FkFilesFileStatus) in the
FileLifecycle mapping file that these objects would be ignored when
writing to the database. However, in the application, I need in some
cases to create 'dummy' FileStatus objects on Filelifecycles objects.
When saving I then get an error re transient objects should be saved
first. How is this if these objects are meant to be ignored. I had
planned on using the FileStatusCode to set and update the FileStatus
on each FileLifeCycle.
As i said i could be missing something simple or am attempting
something thats not meant to be.
Any pointers would be greatly appreciated.
many thanks
