Jeremy,
One more point:
When the result of filter in the set widget is tiddlers with space in the
name like *My Tiddler*, the list widget return* [[My Tiddler]]* this cause
the code breaks. Note to [[]] in the result.
Based on your explanation I used the following syntax
\define nextItem(parent)
<$set
filter=*{{{** [tag[$parent$]after{!!temp}]}}}*
name=NewIndex
emptyValue='[tag[$parent$]first[]]'
>
<$action-setfield
$tiddler={{!!title}}
temp=<<NewIndex>>
/>
</$set>
\end
*No it works!* I mean the new code works even when the filter return [[My
Tiddler]]?
Is it the correct way?
