I am trying to create FeedbackPanel within each ListView component. The
problem is how the visibility is handled... from what I understand, the
order of events occurs like this:
updateFeedback is called on my FeedbackPanel
ListView re-creates all of my components, thus ignoring the visiblity
flag set in updateFeedback
Because of this, my feedback panels never show.
If i set ListView#setReuseItems( true ), I get an NPE:
Caused by: java.lang.NullPointerException
at wicket.markup.html.list.ListView.renderItem(ListView.java:701)
at wicket.markup.html.list.ListView.onRender(ListView.java:664)
at wicket.Component.render(Component.java:1726)
at wicket.MarkupContainer.renderNext(MarkupContainer.java:1357)
at
wicket.MarkupContainer.renderComponentTagBody(MarkupContainer.java:948)
at
wicket.MarkupContainer.onComponentTagBody(MarkupContainer.java:882)
at wicket.Component.renderComponent(Component.java:1941)
... 116 more
How can I get this to work (preferably without ListView#setReuseItems(
true )) ??
