In WebPreferences I set

• Set WEBFORMS = %SEARCH{ "Form$" scope="topic" type="regex" format="$topic" separator=", " nonoise="on" }%

There are a few more places where I've desired to generate perference values. Obviously, there could be a performance hit of using a search here, but if cached that could be acceptable.

This appears to give a perfectly valid WEBFORMS value.

However, clicking add form on a page results in

A corrupted version of chooser form.

That's because what you are trying to do is not valid. Here's how it works:

1. You set the variable WEBFORMS to the value %SEARCH{...}%
2. TWiki parses that value into a list, separating on ,
3. TWiki formats the list as an option select

Note the missing step between 1 and 2; TWiki does not expand variables embedded into the list of forms.

You can try requesting this as an enhancement, of course. Raise a brainstorm topic in Codev.
