Re: DropDownChoice/Model Confusion
The code looks ok. Maybe the problem is in childRecordService: childRecordService.getList() when method getList() does not reflect changes until you create a new session. So maybe the problem is related to your service layer? Have you checked whet this method returns inside childRecordsModel.load() ? -- Daniel On Tue, Oct 5, 2010 at 10:23 PM, Shelli Orton shelli.or...@sjrb.ca wrote: This is what my class basically looks like, hope it helps: - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
RE: DropDownChoice/Model Confusion
No, the getList() (called in the LDM load()) is only called once. For the
buttons add, edit and delete, the processng is like this:
- ldm.load() (which calls getList())
- button.onSubmit()
- ldm.detach() (called two times)
For the save button, the processing is:
- button.onSubmit()
- ldm.load()
- ldm.detach() (called two times)
I've discovered another anomaly in my code. When I choose a record and click
the edit button, the record is displayed in the edit group. If I then choose
cancel, the edit group is no longer displayed and the ddc selection is null. I
then choose another record from the list and edit and the previous record
information is displayed in the edit group even though the ddc shows the newly
selected record.
I added get/set for the selectedRecord and set breakpoints, but those methods
are never called. Since the edit group components use PropertyModels,
shouldn't the get method be called each time the page is submitted?

I created the EditGroup so that I can hide/display the edit panel.
Debugging the application shows that the save button onSubmit is

before the update of the myRecordsModel LDM and this is why the list

updated when I create/edit a record. The delete button onSubmit is
called after the update of the myRecordsModel LDM and that is why a
deleted record is still visible in the list.
I think the issue has something to do with the buttons being in

onSubmit?

Hi, instead of passing getMyRecords() in the constructor wrap it
around
a LoadableDetachableModel and pass that model to the DDC. The difference
is
that your current list is fetch only once at construction of your pages
and
is considered static because its never get called again unless you
triggered
it by entering to a new page instance, while by using a LDM the
component
will ask for it every time it needs to re-render them.

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 DropDownChoiceMyRecord(records,
new PropertyModelMyRecord(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!

Hi, instead of passing getMyRecords() in the constructor wrap it
around
a LoadableDetachableModel and pass that model to the DDC. The difference
is
that your current list is fetch only once at construction of your pages
and
is considered static because its never get called again unless you

it by entering to a new page instance, while by using a LDM the

RE: DropDownChoice/Model Confusion
Hmm, that code sort of works. When I create or edit a record, the list
is updated. However, when I delete a record it is not. My component
hierarchy is set up like this (hope it makes sense):
TabPanel
- SelectForEditForm
- MyRecords (DDC)
- Add (Button)
- Edit (Button)
- Delete (Button)
- EditGroup (WebMarkupContainer)
- EditForm
- MyRecord Name (TextField)
- MyRecord Attribute (DDC)
- Save (Button)
- Cancel (Button)
I created the EditGroup so that I can hide/display the edit panel.
Debugging the application shows that the save button onSubmit is called
before the update of the myRecordsModel LDM and this is why the list is
updated when I create/edit a record. The delete button onSubmit is
called after the update of the myRecordsModel LDM and that is why a
deleted record is still visible in the list.
I think the issue has something to do with the buttons being in
different places in the component hierarchy. Can you provide any
guidance on if there's some way to have the LDM updated after the delete
onSubmit?
Thanks again,
Shelli

Yes, that should make your DDC to query the list any time it needs to re

To your 2nd. question in order to set a default or selected value, just
set
a MyRecord reference to your property, keep in mind that your
MyRecord

Currently my dropdownchoice model is set like this: MyRecord selectedRecord; ... form.add(new DropDownChoiceMyRecord(records, new PropertyModelMyRecord(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!
