DropDownChoice does not push value into Model
Hi All,
http://apache-wicket.1842946.n4.nabble.com/file/n2323809/Code.txt Code.txt
I have a drop down choice control on the search panel and its selected
choices are pushed to the model only once or the first time.
Please have a look at the attached code:
As part of this code, I noticed that when I uncomment the following line,
the drop down choice works every time.(as it is supposed to)
public void initialise(String id){
//cpm.getObject().setStudy(searchCriteria);///Set the search criteria object
back in order for status to be filled in the next submit/search
}
However, this will not resolve my issue, because if I refreshed the study in
the model when the details page is loaded, the problem re-occurs.
Not sure why this is hapenning, I tried to debug as much as I can, all i can
get to is, when i re-set the model's study instance after the search results
have arrived , then it works. If I do not, then it fails to capture the
value from DDC.
Thank you again
Cheers
Niv

Hi James
protected void doLookup(AjaxRequestTarget target, Study studyReference);
I really do not need this studyReference. That was just a test I wanted to
do. It is the study reference that is used to populate the dropdown. I
wanted to see if it gets changed with each submit. I noticed that it does
not change.
I do get the ModelObject -
StudyContainer studyContainer = (StudyContainer)this.getModelObject();
So yeah it works with this change, using PropertyModel. Wanted to get your
feedback if I have used it correctly.
Cheers

Re: DropDownChoice does not push value into Model
Posted by James Carman <ja...@carmanconsulting.com>.
In your onSubmit() method, you're referring to the local variable
"studyReference." Why not try getting the model value while inside
the method?

Re: DropDownChoice does not push value into Model
Posted by nivs <sh...@gmail.com>.
Hi James
Point(s) noted. I have got something going here and it is working but is
this what you meant? Please see attached code and do bear with my questions.
The variable studyReference which is the one that is wrapped within a
PropertyModel, remains or maintains the same reference even if the object
model is changed. So that is the key I suppose not to change the study
reference bound to the DDC any time and we wrap this in a property model.
Still have to get to grips with Models.
Thanks for the help
Cheers

It should be:
new PropertyModel<String>(pModel, "studyName").
The first argument to PropertyModel's constructor is the "root" for
the property expression. If it's a model, Wicket knows to get the
model's object and apply the property expression to that. What you're
doing is telling Wicket to set up a property model where a String is
the "root" and the propertyExpression is "studyName." There is no
"studyName" property on the String class, so that won't work. Also,
your expression and your model type (<Study>) don't match here.
You're telling it to traverse to the study name (which is a String I
assume) and you're saying the model is of type Study. The property
navigation you're trying to do won't work either. All that does is
traverse the property before the method is called and passes its value
in to the method as a parameter. It's not "recording" anything. I
would just go with the simplest solution for now to get you going.
Don't try to get too fancy too fast. Walk before you run.

Could you please clarify this for me, I noticed is that with PropertyModel
usage in the above context.
I have to define one(PropertyModel instance) for each of the form component
explicitly, like so
1. Model<StudyModel> studyModel = new Model<StudyModel>(new
StudyModel());/Top level Model
In the Form:
I associate the studyModel above in the constructor and
Model<StudyModel> pModel = (Model)getModel();
2. firstName = new TextField("studyName",new
PropertyModel<Study>(pModel.getObject().getStudyName(),"studyName"));
// I am manually telling it to navigate to a property ..thought it will be
nice if its automatic based on the expression
I am unable to create a single instance like
PropertyModel<Study> propertyModel = new PropertyModel<Study>(studyModel,
"study");
And then use propertyModel instance for each component.
Am I missing something here?
Thanks again
Niv

James,
Thanks for that. I am trying to implement what you have mentioned using
Model and PropertyModel. Let me get back to you after I have done this bit.
Appreciate your time and advice.

Re: DropDownChoice does not push value into Model
Posted by James Carman <ja...@carmanconsulting.com>.
Why are you using CPMs and PropertyModels together? I would go one
way or the other. In your case, since you're just starting out it
seems, I'd just use a regular model for the main object and use
explicit property models to bind its properties to your components.
The CPM is just too "magicy" and it can get confusing for beginners.
So what you want is:
Model<StudyModel> studyModel = new Model<StudyModel>(new StudyModel());
PropertyModel<Study> propertyModel = new
PropertyModel<Study>(studyModel, "study");
See how I use the "studyModel" as the "root" of my PropertyModel
rather than the StudyModel object contained in the studyModel itself?
That's perfectly okay. What you're telling the PropertyModel is "go
to this model and ask for its object and then ask for its 'study'
property." So, when you change the object that the studyModel points
to, the propertyModel can still get to it. Does that make sense?
With this approach, you can feel free to do setModelObject(new
StudyModel()) and it will work.

Re: DropDownChoice does not push value into Model
Posted by nivs <sh...@gmail.com>.
James
Thanks for pointing it out. Later in the code I have added, so the study
object/instance in the initial model should be in synch right? Correct me if
I am wrong. Let me also think about this point u made. But yeah do let me
know if i have made a mistake.
cpm = (CompoundPropertyModel<StudyModel>)this.getModel();////reset the
original one
Cheers

Re: DropDownChoice does not push value into Model
Posted by James Carman <ja...@carmanconsulting.com>.
Your DDC is bound to the original StudyModel's study with the lines:
PropertyModel propertyModel = new
PropertyModel(studyModel.getStudy(),Constants.STUDY_STATUS);
studyStatusDpChoices = new
DropDownChoice(Constants.STUDY_DROP_DOWN_CHOICE,propertyModel,studyStatusList,defaultChoiceRenderer);
Then, you're replacing the StudyModel with this line:
this.setModelObject(new StudyModel());
Thus, they get out of synch.
