SID-01856: Displaying a topic's parent formfield data

I'm trying to display formfield data from a topic's parent. I found this topic from 2005:

VariableInFormField

One of the last comments was that this should work in the Dakar release.

This is what I have tried:

%FORMFIELD{"Title" topic="%META{"parent" dontrecurse="on"}%"}%

%FORMFIELD{"Title" topic="%PARENTTOPIC%"}% (turns out PARENTTOPIC isn't available on TWiki 5.0.2)

If I explicitly put the topic name in it works:

%FORMFIELD{"Title" topic="MyParentTopic"}%

Discussion and Answer

If you use %META you likely need to specify the format and topic parameter. Details in VarMETA.

Thanks, Peter!

For future searchers...

%FORMFIELD{"Title" topic="%META{"parent" dontrecurse="on" format="$topic"}%"}%

The format term is required because otherwise the %META% variable returns the parent in the form

[[$web.$parent][$parent]]
