Make sure you've manually specified a tomahawk.taglib.xml file.
There's an example on the wiki. (something like

Yes, I have the same situation, and I do it by creating *ItemProvider
class beans with methods similar to this. If the scope of the bean
is request, then the data is fetched once. If session, once per
session. If application, once per application. Or it can be
preserved across requests by using t:saveState.
private SelectItem[] announcementItems = null;
public SelectItem[] getAnnouncementItems()
{
if (null == announcementItems)
{
announcementList = coreCustomerDataStore.getAnnouncementList();
announcementItems = new SelectItem[announcementList.size()];
for (int index = 0; index < announcementList.size(); ++index)
{
Announcement announcement = (Announcement)
announcementList.get(index);
announcementItems[index] = new SelectItem(announcement,
announcement.getUIDisplayLabel());
}
}
return announcementItems;
}
