James,
When doing something similar a while ago, I found that trying to
persist saved queries into the database was more trouble than its
worth. What I ended up doing was saving them to the file system, and
doing something similar to what you're trying - stored the global
ID. The nice thing is though, you can persist a hierarchical
structure of EOQualifiers into a file much more easily than a table
structure.
A good compromise would be to persist the eo qualifiers as text, then
store THAT in a single blob in the database. You'd also gain the
ability to version your structures, so that you could handle loading
old queries, etc.

Well I have a query and reporting system. The user can select
multiple eos from a list, etc., a query is then created, but now I
have to store the query into a database. So.. don't I need to store
the users eo selection via the global ids?
I realize I could model the reports differently but I have been
saving all the queries in a archivable mutable array or dict. These
new custom query components need to be saved too, so I figure the
global ids and the dictionaries to keep in consistent.

Hi James
I think you'll find you don't need to touch the global ID's at
all. Yes there is a way you could extract them, but I wasn't going
to tell you until we'd determined that you really really need to
do it. However Chuck explained how :D
Can you explain what exactly it is you are trying to do. Such as
how is the list of object being selected in the first place ? What
are the objects ? Im assuming they are EO's ?

Hello -
I need to save selection of objects in my database. In order for
me to do that
do I have to first extract their global ids and then store those?
If so is there a magic one line of WebObjects code that gives me
the ids?
Thanks
