SID-01038: No such template def TMPL:DEF{PROMPT:myComment}

Status:	Answered	TWiki version:	5.0.1	Perl version:	5.12.2
Category:	CommentPlugin	Server OS:	Ubuntu Linux 10.10	Last update:	15 years ago

Converting from 4.3.1 to 5.0.1. Comment plugin can no longer locate custom templates, giving message "No such template def TMPL:DEF{PROMPT:myComment}".

UserCommentsTemplate contains: %TMPL:DEF{PROMPT:myComment}%%TMPL:P{promptbox}%%TMPL:END% %TMPL:DEF{OUTPUT:myComment}%%TMPL:P{problemtext}%%POS:BEFORE% %TMPL:END% %TMPL:DEF{problemtext}%---++++++ !!%WIKIUSERNAME% - %SERVERTIME% %URLPARAM{"comment"}% %TMPL:END%

Discussion and Answer

I actually understated the problem. The plugin cannot locate ANY template! I changed one to use the default template and got: No such template def TMPL:DEF{PROMPT:above}

-- LarryBristol - 2010-11-29

Not so intuitive, but of you define your own comment template page you need to include the generic comment template: %TMPL:INCLUDE{"%SYSTEMWEB%.CommentPlugin"}%. See example at SupportCommentTemplate.

I have added that, but it seems to make no difference. The thing is, the CommentPlugin was working in TWiki 4.3.2, and all I have done is copy it into 5.0.1 system. I am obviously overlooking something very basic. Here is the complete contents of "UserCommentsTemplate":

User Templates for CommentPlugin - See %TWIKIWEB%.CommentPlugin#Customisation for help.

Please see my comment in SID-01041 concerning a possible perl problem.

-- LarryBristol - 2010-12-02

I am still floundering out here, guys. Please help! Nothing I have tried has made any difference at all. I even reinstalled TWiki completely. The CommentPlugin cannot locate any template, including the ones built-in. I cannot turn over the new system until this significant piece of functionality is working again!

-- LarryBristol - 2010-12-06

As I stated previously, CommentPlugin cannot find any template, including the built-in ones. I can now state categorically that it has nothing to do with perl.

It simply cannot find any templates unless I explicitly tell it where to look.

This works: %COMMENT{ templatetopic="%SYSTEMWEB%.CommentPluginTemplate" }%

This does not: %COMMENT{ }%

I would appreciate some help. I cannot turn 5.0.1 over into production until I get this resolved.

I am puzzled. Did you do a clean install of TWiki or upgraded over an existing TWiki? Did you use configure to initially create the twiki/lib/LocalSite.cfg?

-- PeterThoeny - 2010-12-10

It was originally a brand new install, and I used the configure script. I later copied the user webs into the directory tree. There was some trouble with getting the initial configuration done. I do not recall what it was now.

But something is clearly wrong... the configuration file is actually located in twiki/bin/LocalSite.cfg! I will attach the file. I also see a directory named twiki/bin/NOT SET that seems to make me recall some bad memories about getting the initial configuration done.

-- LarryBristol - 2010-12-10

There is a twiki/bin/LocalLib.cfg which defines just the location of the twiki/lib. All config settings are at twiki/lib/LocalSite.cfg.

Make sure your TWiki web (e.g. twiki/data/TWiki and twiki/pub/TWiki) is virgin from the 5.0.1 package. Delete the twiki/bin/LocalSite.cfg and redo the configure.

-- PeterThoeny - 2010-12-10

The file you attached is odd. It combines twiki/bin/LocalLib.cfg and twiki/lib/LocalSite.cfg into one. Split them up into two. twiki/bin/LocalLib.cfg has the first few lines up to 1; # Required for successful module loading, and the rest goes into twiki/lib/LocalSite.cfg. Make sure the latter one is writable by the Apache webserver user.

-- PeterThoeny - 2010-12-11

OK. I did as you suggested. I deleted the twiki/data/TWiki and twiki/pub/TWiki directories and rebuilt them by copying a virgin 5.0.1 package, and reran the configure script. Other than eliminating a few plug-in files, it seems to have had no effect at all. I will reinstall the plug-ins later.

I examined the twiki/bin/LocalLib.cfg file. It contained only the lines you specified, mostly comments ending with the 1; # Required for successful module loading. I will attach that file.

I edited the twiki/lib/LocalSite.cfg file, removing all of those leading lines that were in the other file. I will attach that file, as well.

Unfortunately, this seems to have had no effect either.

The easiest way for me to test this is to display the TWiki/CommentPluginExamples topic, where I get the "No such template def TMPL:DEF{PROMPT:-fill-in-the-name-}" message for every one of the built-in templates. I'm not worrying about my custom templates for now; I figure they will start working as soon as the built-in templates work.

I appreciate your efforts! I'm sure it will turn out to be something simple in the end, but it seems to be way over my head at the moment.

Closing this question after more than 30 days of inactivity. Feel free to reopen if needed. Consider engaging one of the TWiki consultants if you need timely help. We invite you to get involved with the community, it is more likely you get community support if you support the open source project!
