Hi,
I've just made an upgrade to 1.3-SNAPSHOT. And now I have a problem
with customizing PagingNavigator component, because of moving creation
of components to onBeforeRender() method.
In out navigator we want to hide (remove) some links (eg. first and
last). So I have a constructor like this:
public FooterPagingNavigator(String id, IPageable pageable) {
super(id, pageable);
remove("first");
remove("last");
}
Now the exception is thrown because these links are added in
onBeforeRender(). So I can change our component and move code from
constructor to onBeforeRender(), but now in this method in
PagingNavigator there is a condition:
if (get("first") == null)
{
...
}
So each time I remove "first" component the code inside condition will
be called - so exception will be thrown then.
The question is why this condition is in such form:
if (get("first") == null)
and no like this:
if (!hasBeenRendered())
?
Then I will be able to remove components using the same condition.
