Question

I am puzzled. I think this should work:

<!--
   * Set TOPICPARENT = %META{"parent" dontrecurse="on"}%
-->

---+  %FORMFIELD{"ProjectName" topic="%TOPICPARENT%"}%

but the header is suspiciously missing.

A simple

My parent is %TOPICPARENT%

shows the value I expect and that parent page does have a form attached with the ProjectName field filled in.

I can't make this work either

---+!!  %FORMFIELD{"ProjectName" topic="%META{"parent" dontrecurse="on"}%" }%

Can someone explain? This looks like a bug. Is there some syntactic incantation I can do to make it work?

If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list below the edit box.

Erm.... I seem to recall that Crawford informed us that you have to use format="$topic" in Codev.ParentTopicVariable? We both missed it since it is not (yet) documented in TWiki.VarMETA, though it works at twiki.org. Let me try: I edit this topic to use Support. ParentTopicVariable as parent, and then pull the formfield SupportStatus in:

<!--
   * Set TOPICPARENT = %META{"parent" dontrecurse="on" format="$topic"}%
-->
---+  %FORMFIELD{"SupportStatus" topic="%TOPICPARENT%"}%
This topic's parent is %TOPICPARENT%. the heading above shows the parent's !SupportStatus field.
