Ha. I have no idea! It's just what dropped out of the bottom of 2 hours of fishing around and trial and error!
It did also solve my original problem too around storing the final used name into a field. Using one of the the same 'dummy' tiddler's fields to store it and read it back again did the trick. Relevant code: <$action-createtiddler $basetitle={{$:/_opTaskStore!!taskname}} $savetitle="$:/_opTaskStore!!finalname" shorttext={{$:/_opTaskStore!!description}} tmap.id={{{ [[]make[%uuid%]] }}} assignedto={{$:/_opTaskStore!!assignedto}} caption={{$:/_opTaskStore!!caption}} tags="[[Task]]" color={{$:/_opTaskStore!!color}}/> <$action-navigate $to={{$:/_opTaskStore!!finalname}}/> Relevant part being $savetitle="$:/_opTaskStore!!finalname" -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
