This tag is commonly used in skins to render the breadcrumbs of a topic page. Unfortunately the implementation of this tag returns not only the parent but also the squared brackets to make it a twiki link. This is superfluous as the renderer does so on its own (given surrounding whitespaces).

So I'd propose that

%META{"parent" dontrecurse="on"}%

ParentWeb.ParentTopic

[[ParentWeb.ParentTopic][ParentTopic]]

Here's the patch

This issue arose during TWiki:Support.HowToIncludeAllParentTopics.

This is a compatibility issue. The reason for the bracket link is so that non-WikiWord topics get linked properly, such as Singelton, Y2000Question, Topic_With-Dash-etc.

This should be enhamced with compatibility in mind, such as a format parameter.

I reverted the change since it broke parent display if the parent has a non-WikiWord name. Example:

Sandbox web > TestTopic1 > Sandbox.Foo-Bar > ChildTopic

Please enhance with a format="" parameter or the like.

Done. -- MD
