ItemPanel(String, MenuRow) is called by newItemPanel(String, MenuRow)
is called by populateItem(ListItem). Populate item looks like this:
protected void populateItem(ListItem item)
{
final MenuItem menuItem =
(MenuItem)item.getModelObject();
final Panel itemPanel =
menuItem.newItemPanel("itemPanel", MenuRow.this);
if (itemPanel == null)
{
throw new WicketRuntimeException("item panel
must be not-null");
}
if (!"itemPanel".equals(itemPanel.getId()))
{
throw new WicketRuntimeException("item panel
must have id
'itemPanel' assigned");
}
itemPanel.setRenderBodyOnly(true);
item.add(itemPanel);
}
The problem with that code is this line:
itemPanel.setRenderBodyOnly(true);
that should be itemPanel.setRenderBodyOnly(false); or be removed to
have any attribute modifier work (as with true, there is no attribute
as there is no tag).
Thanks for finding that bug, and sorry that you spent a lot of time on it.
Cheers,
Eelco
