Can't insert after last repeat node deleted

The problem is that after I delete the only remaining row in the repeat the Add button no longers works.

Padding my post with extra stuff so that the question gets accepted

Solution

  • You have two options:

    1. Disable the Delete button when only one item remains. The XForms Wikibook shows how: http://en.wikibooks.org/wiki/XForms/Disable_Trigger
    2. Set the origin of the rows to a different instance, not to the last row of the repeat. Read this article to see how: http://en.wikibooks.org/wiki/XForms/Insert_with_Origin

    HTH!
