SID-02344: varFORM and $formweb

Is var %FORM% still working in TWiki 6.0.2? %FORM{format="$formweb"}% or %FORM{format="$formtopic"}% doesn't seem to work. I can use %FORMFIELD{"name" format="$formtopic"}% to retrieve the name of the topic containing the form definition, but %FORMFIELD% doesn't support $formweb, so when the form is on another web, I will get a link which is not working.

Discussion and Answer

Hm.... According to the source, it seems that $formweb never has worked when the form and topic are in the same web, but you use the form variable from another web. The symptom is that $formweb is expanded to the web where you use the %FORM% variable - is that correct?

If so, then You seem to have found a (yet another) bug. I'll attach the trivial fix. Do you want to file a bug report or should I do it myself?

BTW: If form and topic are in different webs, or if the topic using the form and the topic using the %FORM% variable are in the same web, it's ok.

Harald, since I'm not a programming expert and I even don't know where to look in the source, as you did, it seems best that you make a bug report. In my TWiki %FORM% isn't expanded at all. That is why I was asking if %FORM% is still working in TWiki 6.0.2. Thanks for answering my question.

Hello Emiel,

if %FORM% isn't expanded at all, then perhaps you didn't specify a topic which uses a form? In that case, there's just an empty output and no error message. I'm writing that because this is the error I made when I first tried it: for the topic parameter I specified the name of the form, which is just wrong.

Just let me try here with our previous experiment in SID02334DemoTopic:

%FORM{topic="Sandbox.SID02334DemoTopic" header="on" formfields="all"}%

Renders as:

Oh, drats. It doesn't render at all: twiki.org doesn't run 6.0.2 yet: The FORM variable didn't exist in previous versions.
