No problem.
But ... erm ... I've another question: In my application there is a table which
contains priorities. The table contains two columns: the ID and the description
of the priority. On some pages the user can filter all shown entries by
priority. Adding a noSelectionLabel the user has also the option to disable the
filtering.
But now the user should be able to filter for priorities greater or less than a
distinct value, say 3. So I want to add two further rows in the si:selectItems
which have this special meaning. I know that the EntityConverter can't handle
rows, which are created in my bean and not persisted in the database.
So I think the best solution would be a custom converter which handles the
special meanings and invokes the EntityConverter for all the other cases.
Is that possible?
Has to be something like this (got it from the wiki):
public Converter getPriorityConverter() {
| return new PriorityConverter<Priority>() {
|
| protected Object getIdAsObject(String id, Class clazz) {
| int priority = Integer.parseInt(id);
| if(priority == -2) return SpecialPriorities.GREATER_3;
| if(priority == -3) return SpecialPriorities.LESS_3;
| Converter entityConverter = new EntityConverter();
| return entityConverter.getIdAsObject(id, clazz);
| }
|
| protected String getIdAsString(Priority entity) {
| return entity.getId() + " (" + entity.getDescription() + ")";
| }
| };
| }
