Steps to Reproduce

1. add the following to UserCommentsTemplate

Add Checklist Item

%TMPL:DEF{PROMPT:checklist_table}%
%TABLE{ valign="top" }%
| Add Checklist Item ||||||||
| *Status* <br/> <input %DISABLED% type="hidden" size="16" name="clitem_id" value="%SERVERTIME{$year$month$day$hour$min$sec}%" />%N% | *To Do* <br /> <input type="text" size="30" name="to_do" value="" /> | *Comment* <br /> <input type="text" size="50" name="comment" value="" /> |  <input %DISABLED% type="submit" value="%button|Add New Entry%" /> <br/> %CALC{"$IF($EXISTS(%WEB%.%TOPIC%ChecklistItemState), [[%TOPIC%ChecklistItemState][maintain states]], )"}% |
%TMPL:END%

%TMPL:DEF{OUTPUT:checklist_table}%| %CLI{id="%URLPARAM{"clitem_id"}%"}% | %URLPARAM{"to_do"}% | %URLPARAM{"comment"}% |%POS:BEFORE%
%TMPL:END%

2. use the comment template as follows

%COMMENT{type="checklist_table"}%

3. observe the problem

The following appears in the template (instead of the result of the "if exists" test):

%CALC{"$IF($EXISTS(CheckListT…tItemState), maintain states, )"}%

What on earth is %CLI? AFAIK that's nothing to do with either plugin, nor the core.

-- TWiki:Main.CrawfordCurrie - 27 Jul 2007

Hi Crawford, a %CLI is from the TWiki:Plugins.ChecklistPlugin. Does it's existence in the template mean that the bug is invalid ?

-- TWiki:Main.KeithHelfrich - 03 Aug 2007

The question is if you also have the bug when you do not have the %CLI in the template.

It is a bit of a task having to install ChecklistPlugin to verify your problem.

-- TWiki:Main.KennethLavrsen - 27 Aug 2007

Bug confirmed.

See Item4423Test

Release blocker? Borderline I would say.

-- TWiki:Main.KennethLavrsen - 27 Aug 2007

We have been discussing back and forth a few times on which tags CommentPlugin should expand up front and which it should delay.

As I remember it we have sometimes ended up in it being a feature request to be able to state explicitely which tags are wished expanded at comment time and which are not.

Not a release blocker, more of a feature request / wish for functionality. Should be discussed in a Codev topic imho.

-- TWiki:Main.SteffenPoulsen - 27 Aug 2007

I agree it is not a release blocker.

Steffen do we have a Codev topic that already covers this?

And to anyone - is there a workaround that Keith can use?

-- TWiki:Main.KennethLavrsen - 27 Aug 2007

TWiki:Plugins.CommentPluginDev has a little discussion and a few workarounds (along the lines of pre-calculating needed values and putting them in a variable up front).
