When a tiddler is viewed or edited, then within its branch of the widget tree, the storyTiddler variable contains the title of that tiddler.
The default view template and edit template initialise storyTiddler
to the value of the currentTiddler
variable. This in turn will have been set by a $list
widget in the relevant part of the page template.
storyTiddler
is undefined outside the story river, such as in the sidebar.
