I have following related problem with wicket-phonebook and FilterToolbar API Change:
When I hit back button and then try to sort using column names in the Actions header of the table, I receive: WicketMessage: Error attaching this container for rendering: [MarkupContainer [Component id = users, page = com.revedex.shop.web.page.ListContactsPage, path = 20:filter-form:users.DefaultDataTable, isVisible = true, isVersioned = true]] Root cause: java.lang.NullPointerException at org.apache.wicket.markup.repeater.data.DataViewBase$ModelIterator.hasNext(DataViewBase.java:121) at org.apache.wicket.markup.repeater.AbstractPageableView$CappedIteratorAdapter.hasNext(AbstractPageableView.java:371) at org.apache.wicket.markup.repeater.DefaultItemReuseStrategy$1.hasNext(DefaultItemReuseStrategy.java:65) etc... How to fix this and still have 'back-button' supported? I have not observed the problem in 1.2.6. Many thanks, Pavol UPBrandon wrote: > > That worked perfectly.
