<<forEachTiddler>> dynamically generates and shows content. However,
the output from <<forEachTiddler>> isn't actually stored as data
anywhere. It is simply rendered into the story column when the
tiddler is displayed. Thus, it is not available for use by
<<openStory>> [1] which needs *data* contained in the source text of a
stored tiddler.
Fortunately, what you are trying to do is actually very
straightforward to write as direct, inline javascript code [2] to
perform the entire process using standard TW core functions,
store.forEachTiddler(...), store.getValue(...), and
store.displayTiddlers(...)
<script>
var titles=[];
store.forEachTiddler(function(title,tiddler){
var val=store.getValue(title,'fieldname');
if (val==undefined) return; // no field... ignore this tiddler
titles.pushUnique(val);
});
store.displayTiddlers(null,titles);
</script>
note: the above code assumes that for any given tiddler, the
'fieldname' in question contains a single tiddler title to be used.
However, if we were to suppose that the field contains a space-
separated *list* of tiddler titles to be used, then instead of simply:
titles.push(val);
you could write something like:
val.readBracketedList().map(function(title)
{titles.pushUnique(title);});
enjoy,
