Subject [jira] Commented: (COCOON-1808) Allowing String labels in forms StaticSelectionList
Date Mon, 03 Apr 2006 09:26:44 GMT

Rob Berens commented on COCOON-1808:

An example use case.

In this use case I create a filter selection list to filter a subcollection based a single
value for a certain property of the elements in that collection. To prepare this filtering
the collection has been divided in so called subgroups beforehand. Those subgroups are iterated
to retrieve the filter value and their count.
In the selection list the individual items are labeled by their value and between parentheses
the number of times they occur in the collection. The following code fragment illustrates

        StaticSelectionList list = new StaticSelectionList(filterField.getDatatype());
        for (
            Iterator i = subGroupIterator();
        ) {
            Group subGroup = (Group);
            String value  = subGroup.getValue().asString();
            list.addItem(value, value + " (" + subGroup.getElementCount() + ")");

> The StaticSelectionList in the forms block only allows for XMLizable labels to the added
items. In some cases it is handy to be able to supply String labels just like in e.g. AbstractJavaSelectionList.
I therefore added an addItem(Object, String) method. Note that this makes calls like addItem(someValue,
null) ambiguous. Therefore I also added an addItem(Object) method.
