Re: [Betterform-users] Unable to delete nested repeat elements - debugger outputs blank blue lines
|

You might not be using the right "context" in your delete. There are two
styles, one that you put the delete in each row of the repeat and one that
you reference the current selected item.
You might also want to shift from "nodeset" to "ref" since "nodeset" is no
longer being used:
<xf:delete nodeset="level.doors" at="index('level.doors.repeat'
)"></xf:delete>
change to remove the nth item in a repeat which is the selected item. Use
a predicate to find the nth door.
<xf:delete ref="instance('level.doors.template')//door[
index('level.doors.repeat')]"/>
Try that!
