I am writing a (simple?) database CRUD app where I have multiple tab
panels that encapsulate the different tables in the database. On a
panel there's a dropdownchoice which lists the existing records for that
table. There's also create, delete and edit buttons (and and edit panel
with save and cancel buttons). When I create, edit or delete any of the
records, the dropdownchoice list doesn't reflect the changes until I
open a new session. So my question is how to reload the list after one
of these actions is done?
Currently my dropdownchoice model is set like this:
MyRecord selectedRecord;
...
form.add(new DropDownChoice<MyRecord>("records",
new PropertyModel<MyRecord>(this, "selectedRecord"),
getMyRecords(), // method that retrieves from the database (via
JPA)
new MyRecordRenderer()).setNullValid(false)); // used to return
the display attribute of MyRecord
I am trying to understand if using a LoadableDetachableModel will do the
reload that I want. Also, I don't know how to set the selectedRecord
using that type of model or if it's even possible.
Any advice?
Thanks!
Shelli
