Re: [wicket-user] List of DropDownChoices
Martijn,
thank you so much for your help.
Now it works perfectly. I added the field "paxProAnreise" to the
TerminDetail class, added getters and setters and changed the
PropertyModel accordingly. Now my code looks like this:
protected void populateItem(ListItem item) {
final TerminDetail terminDetail = (TerminDetail)
item.getModelObject();
boolean visible = terminDetail.getFreieKontingente() > 0;
item.add(new Label("zimmerart",
terminDetail.getZimmerart()).setVisible(visible));
item.add(new DropDownChoice ("moeglichePaxAnzahlen",
new PropertyModel(terminDetail, "paxProZimmerart"),
terminDetail.getMoeglichePaxAnzahlen()).setVisible(visible));
}
Now it works like a charm :)

Hi,
I'm new to Wicket and I have a question. I need to generate and
display
a List of DropDownChoices. This is the scenario:
I have different room types and for every room type I have certain
vacancies. So I need to have something like this:
Double room - [Choose one ]
[2 ]
[4 ]
[6 ]
Single room -[Choose one ]
[1]
[2 ]
[3 ]
[4]
I already managed to display that (with a list view and a
DropDownChoice
attached to each item). But when I want to submit the form, I get an
exception.
What would be The Right Thing to do?
Thank you so much!
- Johannes

Re: [wicket-user] List of DropDownChoices
Johannes,
You haven't attached a model to the dropdown choice. The constructor you
are using implies having a CompoundPropertyModel as ListItem.model. You
don't have this, so you need to use another constructor:
item.add(new DropDownChoice ("paxProZimmerart", new
PropertyModel(terminDetail, "paxProZimmerart"),
terminDetail.getMoeglichePaxAnzahlen()));
Looking at your code, I suspect you will be getting other exceptions, as
you render your components conditionally, this will give exceptions.
Better to use:
protected void populateItem(ListItem item) {
final TerminDetail terminDetail = (TerminDetail) item.getModelObject();
boolean visible = terminDetail.getFreieKontingente() > 0;
item.add(new Label("zimmerart",
terminDetail.getZimmerart()).setVisible(visible));
item.add(new DropDownChoice ("paxProZimmerart",
new PropertyModel(terminDetail, "paxProZimmerart"),
terminDetail.getMoeglichePaxAnzahlen()).setVisible(visible);
}
