Item9449: FOREACH macro should expand within STARTSECTION type=expandvariables

If I have a topic template containing this code

%STARTSECTION{type="expandvariables"}%
%FOREACH{"host" in="%URLPARAM{"Hostgroups"}%"}%
   * $host
%NEXT{"host"}%
%ENDSECTION{type="expandvariables"}%

and I create a page using this templatetopic, passing ...&Hostgroups=a%2C+b%2C+c%2C+d

I expect to get

   * a
   * b
   * c

in the resulting page.

%FOREACH should be run and expanded when the template is copied.

Corrected spelling in the component field.

This could be a simple or complex fix; ForEachPlugin doesn't use registerTagHandler(), so as usual these types of macros are difficult to make consistent when it comes to edge cases in macro expansion behaviour.

For what it's worth, Foswiki 1.1's FOREACH macro accomplishes nearly the same thing and is in fact implemented with registerTagHandler()

Thanks. We'll look into Foswiki 1.1's FOREACH macro when we can. That may be a simler way to go. (Is if backward compatible to the Plugin? We have a LOT of pages...)

No, it operates in a very different way. I will try to create an FAQ for how they're different and how to re-work your wiki apps to use the new macro.

We are tracking the issue in Item2382. I have made it a release blocker because you are not the only one that will be burnt by the new feature conflicting with the old plugin.
