Hi,
I think there is some issue with invisible panels. If you only place one panel on a page and define some visibleIf for this panel, the page becomes inaccessible, even if the visibility state of the panel changes.
Here is an example: https://plnkr.co/edit/iMpQ4VHLhCiyrKcRdeEX?p=preview
If you select item1, the panel on the next page becomes visible but you still can't enter the next page.
Thanks!
