I use listbox with paging enabled. In item renderer I create two buttons for the first cell and crate some stubonly cells accroding to article. It's work good, but I have problem with listbox paging: when I switch to previous page (it was showed already) I have error "SEVERE: [Desktop z_xwe:/stubonly.zul] client error: Failed to mount: Unknown stub pDKQe0".
So, actual scenario:

1. Load page http://127.0.0.1:8080/stubonly.zul.
2. Switch to second page in Listbox.
3. Try to switch to previous page and getting error.
   

Project example here.

Can I use stubonly components in listbox? How can I solve this problem?
