Re: Submitting values for null associations
I'm not sure there is a very clean solution. When switching to edit mode, you could set the User's Job to a new Job instance if it is null. You don't have to reattach/reassign any form components if you simply update the AbstractEntityModel's object. I.e. you either do model.getModelObject().setJob(new Job()) or you do model.setModelObject() You will of course have to revert the job property back to null before saving if all its properties are empty. I would implement a Job#isEmpty() method to help me decide if I need to set user.job to null before saving to the db. Note you may also have to delete an existing Job record if the user goes ahead and updates it's name to null.

Re: How to make a Wiket DropDownChoice with complex a model return a simple String
Hi,
I needed something similar in a couple of projects. One solution is to
create a custom DropDownChoice which takes also the string model to
update. Then you can override onModelChanged to update the string model
with the new value that can be extracted with the ChoiceRenderer.
To make this easier to understand, let's say that I have a list of state
abbreviations for example AL, AK, AZ, AR etcetera (the actual example has
two letter abbreviations also, but much longer names). I need a
DropDownChoice that shows the abbreviations for selection (e.g., AK) but
will show the full name as a tooltip whenever the mouse hovers over one of
the choice (e.g., AK shows Alaska).
I have developed a solution that is based on the example presented here:
http://stackoverflow.com/questions/12234738/wicket-dropdownchoice-titles-too
ltips-for-options
that develops a subclass of DropDownChoice and overrides appendOptionHtml
to append a "title" to the buffer. My class takes a StateDisplay object as
its model, and the model has two fields, an "id" that is displayed in the
list, and a "fullName" which is added as the title by the appendOptionHtml
method.
This works fine for displaying thedropdown with the tooltip, but the
problem is that the model is a complex object( StateDisplay) with two
fields, but the underlying domain object needs a simple String with the
state ID.
Prior to implementing the tooltip, the DrowdownChoice was formed using:
Item.add(new DropDownChoice("state", new
PropertyModel((CompanyDTO) item.getDefaultModelObject(), "state"),
stateList)));
Note: "item "is there because this is used in the populateItem method of a
ListView.
Now the code is:
Model< StateDisplay > selectedState = new Model<>();
ChoiceRenderer choiceRenderer = new
ChoiceRenderer("id", "id");
Item.add(new StateDropDownChoice< StateDisplay >("state", selectedState,
stateList, choiceRenderer));
After the selection is made the model (selectedState) is set to the chosen
StateDisplay, but there is no easy way to the simple String value set on
the CompanyDTO.
How can I make the dropdown selection update the domain model's simple
String.
Thanks
Bruce

Re: SpringBean and properties file.
Hi, Wicket uses CGLib proxies, to proxy beans which are not referenced by their interface. This leads to the constructor being fired once for each injection.

I think this is a problem in spring and wicket working together. This is in 1.4.7. In spring: This bean is injected into a wicket page with @SpringBean. Using breakpoints I can see spring insantiating this bean, and setting the properties. The values are there. This happens on application startup.

Re: Submitting values for null associations
I'm afraid I still don't see it. I think I'm just going to have to use a nested model at the form level and rebuild it whenever I toggle viewing/editing mode. So I'd build a new Model() from the unproxied User when switching to edit mode and build a new AbstractEntityModel(user.id, User.class) when switching to viewing. I'd also have to check for empty associations and null then upon saving so as not to have empty associations (rows with just an id) in the db. Seems rather painstaking but I can think of a better way atm...

You use cascade="all" on the job relation. When job is created, it should have at least one non-empty property. Job's instance is null because it doesn't have any non empty property.

As Hibernate save a new Job instance when you save the User if the relation is empty why don't you load the job (with an eager fetching strategy) when you load the user ?

Yes I'm aware of this but the problem is I'm reusing the same AbstractEntityModel (effectively a LoadableDetachableModel that loads from the db) for the edit mode and the User instance in the db has no Job instance (yet). I could always re-build a Model using the unproxied User instance when I flip from view to edit but then all the child form components would need to be reassigned as I'm not rebuilding the view...

Submitting values for null associations
Hi, I have a form which can flip between edit and view modes. Its fields share a common CompoundPropertyModel which in turn points to an AbstractEntityModel similar to that described in the 'Wicket in Action' blog. My problem is with associations that happen to be null. If I have a User entity with a lazily initialised Job association, during viewing all works fine but when I edit the user and enter some text into a field that is bound to User.Job.Name I get a "WicketRuntimeException: Attempted to set property value on a null object". How is this kind of situation generally handled?

Fwd: Feedback Messages prevent DropDownChoice updating Textfields
Hi,
I am trying to implement a Feedback for every Form Component and
a catch all Feedback Panel in wicket 6.12.0. Everything works fine except
for the case
when a user causes a error which is shown in the Feedback Panel of the
Component,
e.g. the Textfield firstName is left empty. After that the select of the
DropDownChoice
does not update the Textfields anymore. Where is my mistake? Thanks a lot
in advance.
