Someone (nick eugs) had a question on the IRC channel today. I gave
the wrong answer unfortunately, and I'm afraid this is quite a common
mistake to make anyway.
Q: I want to change an attribute of the list view. So say, the list
view is attached to tag <tr wicket:id="rows">...</tr>, I want it to
render as <tr myattrib="foo" wicket:id="rows">...</tr>. I tried adding
an attribute modifier to the list view: myListView.add(new
SimpleAttributeModifier("myattrib", "foo")), but it doesn't show up. I
also tried overriding onComponentTag of the list view, but this never
gets called.
A: ListView is a weird bastard. The actual component itself is never
rendered, but for every row, the child components it creates (the
ListItem components you get passed in the populateItem method) get
rendered instead. This is something to get used to, but once you get
the solutions like this question are easy: attach the attribute
modifier to the list item instead of to the list view:
add(new myListView("someid", list) {
protected void populateItem(ListItem listItem) {
listItem.add(new SimpleAttributeModifier("myattrib", "foo"));
...
}
});
If I didn't make any grave mistakes and all, could someone be so kind
to put this (maybe with more list view examples?) in the WIKI
somewhere?
