PropertyselectionModel Q

[Peter Verhoye]

Hi all,

I'm trying to do the following:

We have an object (Account) which contains an other object (Language).
To edit the account, I've created an accountEdit page where I want to
have a dropdown box that shows the list of languages one can set for an
account. But, I want the list to be set to the language the account
already has if available.
So, I've already created the following:

public class LanguageSelectionModel implements IPropertySelectionModel,
Serializable {
        private static final long serialVersionUID = -3912209045599735086L;

        private List<Language> languageList;

        private String languageId;

        public LanguageSelectionModel(List<Language> languageList, String
languageId) {
                this.languageList = languageList;
                this.languageId = languageId;
        }

        public int getOptionCount() {
                return languageList.size();
        }

        public Object getOption(int index) {
                return languageList.get(index);
        }

        public String getLabel(int index) {
                return languageList.get(index).getDescription(languageId);
        }

        public String getValue(int index) {
                return Integer.toString(index);
        }

        public Object translateValue(String value) {
                 return getOption(Integer.parseInt(value));
        }
}

In the AccountEdit.page file I have this:
<component id="language" type="PropertySelection">
        <binding name="model" value="availableLanguages"/>
        <binding name="value" value="account.language"/>
</component>


In the AccountEdit.java file I have the following:
public IPropertySelectionModel getAvailableLanguages() {
        String languageId =
getVisitObject().getContactPerson().getLanguage().getId();
        return new LanguageSelectionModel(getLanguageDAO().findLanguages(),
languageId);
}

Now, this all seems to work except that the combobox does not get
initialised on the correct Language object. Now, I think I know why but
I don't know how I should initialise the PropertySelectionModel.

Anyway has an idea or so?

Thank you!!
