Re: LoadableDetachableModel and Attempt to set model object on null model of component

2013-06-14 Thread Baptiste75 
Ok I eventually made it work.
I have to use a Model for *both* the provided values, AND the selected
object (sorry, I'm a Wicket newbie).
Thus, by adding a field to the page:

public CompanyConfiguration selectedCompany;

And then:

ChoiceRendererCompanyConfiguration choiceRenderer = new
ChoiceRendererCompanyConfiguration(name, id);

DropDownChoiceCompanyConfiguration ddc = new
DropDownChoiceCompanyConfiguration(companiesList,
new PropertyModelCompanyConfiguration(this, 
selectedCompany),
new 
LoadableDetachableModelListlt;CompanyConfiguration() {

@Override
protected ListCompanyConfiguration 
load() {
final 
ListCompanyConfiguration configs = getCompaniesList();

Collections.sort((ListCompanyConfiguration) configs, new
ComparatorCompanyConfiguration() {
@Override
public int 
compare(CompanyConfiguration o1, CompanyConfiguration o2)
{
return 
o1.getName().compareTo(o2.getName());
}
});
return configs;
}

@Override
public void detach() {
}

}, choiceRenderer);

But in my case, this leads to a serialization issue, so again we have to use
a LoadableDetachableModel:

DropDownChoiceCompanyConfiguration ddc = new
DropDownChoiceCompanyConfiguration(companiesList,

new 
LoadableDetachableModelCompanyConfiguration() {

@Override
protected CompanyConfiguration load() {
return null;
}

},  
new 
LoadableDetachableModelListlt;CompanyConfiguration() {  


@Override
protected ListCompanyConfiguration 
load() {
final 
ListCompanyConfiguration configs = getCompaniesList();

Collections.sort((ListCompanyConfiguration) configs, new
ComparatorCompanyConfiguration() {
@Override
public int 
compare(CompanyConfiguration o1, CompanyConfiguration o2)
{
return 
o1.getName().compareTo(o2.getName());
}
});
return configs;
}

@Override
public void detach() {
}

}, choiceRenderer);

LoadableDetachableModel and Attempt to set model object on null model of component

2013-06-14 Thread Baptiste75 
I got a /Unexpected RuntimeException Last cause: Attempt to set model object
on null model of component: form:companiesList/ whenever I select an item in
my DropDownChoice.
I read somewhere that it was because there is no Model set, but there *is*
one (a LoadableDetachableModel) :

ChoiceRendererCompanyConfiguration choiceRenderer = new
ChoiceRendererCompanyConfiguration(name, id);

DropDownChoiceCompanyConfiguration ddc = new
DropDownChoiceCompanyConfiguration(companiesList,
new 
LoadableDetachableModelListlt;CompanyConfiguration() {
private static final long serialVersionUID = 
8752933117323402630L;

@Override
protected ListCompanyConfiguration load() {
final ListCompanyConfiguration 
configs = getCompaniesList();

Collections.sort((ListCompanyConfiguration) configs, new
ComparatorCompanyConfiguration() {
@Override
public int 
compare(CompanyConfiguration o1, CompanyConfiguration o2) {
return 
o1.getName().compareTo(o2.getName());
}
});
return configs;
}
}, choiceRenderer) {

protected boolean wantOnSelectionChangedNotifications() {
return true;
}

protected void onSelectionChanged(final CompanyConfiguration 
newSelection)
{
logger.debug(Selected base:  + newSelection.getId());
}

};

Has anyone an idea about what I'm doing wrong?

Note: I cannot serialize my CompanyConfiguration list.

BTW, second question: there is a DataView with a ListDataProvider elsewhere
in the page. How can I update its values from the method
onSelectionChanged() above?

Thanks a lot!

You need to find if the component who throw the exception is the same agent
constructed with lines you report and on what moment the component lost his
model.

 The only reason i can find is that the field has a null model, but i added
 a new Model() to the field and im still getting it

 DropDownChoiceAgent agent = new DropDownChoiceAgent(agent, new
 ModelAgent(), agentList);

Attempt to set model object on null model of component when submitting a form

2008-09-16 Thread Azzeddine Daddah 
Hi,

I've the following code:

private static final ListString SEARCH_DOMAINS = Arrays.asList(AA,
BB);
...
private void addSearchForm() {
Form searchForm = new Form(searchForm);
searchForm.add(new DropDownChoice(searchDomain, SEARCH_DOMAINS));
searchForm.add(new TextField(areaCode, new Model(),
Integer.class));

Button submiButton = new Button(submiButton) {
private static final long serialVersionUID = 1L;

public void onSubmit() {
info(submiButton executed);
}
};

searchForm.add(submiButton);
add(searchForm);
}

When I hit the submit button I get this error: Attempt to set model object
on null model of component.

Could you please tell me what am I doing wrong?

Gr. Azzeddine

2008-09-16 Thread Stefan Lindner 
Your DropDownChoice element has no Model so the submit code does not know where 
to store your selection. Add a

 new ModelString()

to it's constructor.
