When a page is being edited ('Edit' or 'Raw Edit'):

If I press 'Cancel' I get the following 2 Javascript errors:

  • suppressTWikiSaveValidation is not defined
  • validateTWikiMandatoryFields is not defined

If I press 'Save', 'Quite save' or 'Save and Continue' I get the following Javascript error:

  • validateTWikiMandatoryFields is not defined

This is both in ie6 and firefox
The above actions are still carried out when I ignore the errors (in both ie and firefox)

I suspect that these functions being called, are somehow not beeing included (maybe a .js include is missing) from one of your Javascript libaries.

I actually tried this with a basic installation without installing any additional plugins.

This site is running TWiki version TWiki-4.2.0, Tue, 22 Jan 2008, build 16278, Plugin API version 1.2
Server: Redhat Linux enterprise, Apache 1.3 and Perl 5.008005

Even when I updated the TinyMCEPlugin to the latest version (16598) the errors still occure.

In the '/twiki/templates/edit.pattern.tmpl' templates this section appears:

%TMPL:DEF{"script:skintemplate"}%%IF{"not context TinyMCEPluginEnabled or $nowysiwyg='1'" then='$percntTMPL:P{\"script:skintemplate:edit\"}$percnt'}%%TMPL:END%

%TMPL:DEF{"script:skintemplate:edit"}%<script type="text/javascript" src="%PUBURLPATH%/%SYSTEMWEB%/TWikiJavascripts/twikiPref.js"></script><script type="text/javascript" src="%PUBURLPATH%/%SYSTEMWEB%/TWikiJavascripts/twiki_edit.js"></script><script type="text/javascript" src="%PUBURLPATH%/%SYSTEMWEB%/PatternSkin/pattern_edit.js"></script>%TMPL:END%

it does look to me that the IF condition is not being met. Any reason why? I have both the 'WysiwygPlugin' and 'TinyMCEPlugin' enabled in configure?


I also see JS errors often. Probably in the same situation. Lets us get this fixed in 4.2.1. It cannot be a big deal.

The problem is due to the fact that the IF statement you pointed out prevents twiki_edit.js being loaded when Tiny MCE is in use, but the Tiny MCE javascripts call functions from twiki_edit.js

This requires an understanding of why twiki_edit.js is excluded when Tiny MCE is loaded. It may be necessary to split twiki_edit.js so that those functions are loaded unconditionally.

We need to get this one moving.

Is the quick fix to copy the missing functions to !/pub/TWiki/TinyMCEPlugin/twiki.js?

In that case - which tool do you use to compress the twiki_src.js into twiki.js?

I have also tried to remove the IF from edit.pattern.tmpl. I have not yet seen any negative effect of this but I have not tested much and I fear a potential problem since in the TWikiJavascripts/twiki_edit.js there are functions with same name as in TinyMCEPlugin/twiki.js. But removing the IF does remove the errors in the browser.

We need to get the urgent bugs resolved now so I am going for the quick fixes now. But I need to know how I should compress the js.

Got the answer on IRC

perl build.pl compress is the answer

Will need to test before I check anything in. My plan is to try to copy the missing functions to twiki.js in TMCE plugin. Seems to be the low risk and easy way.

-- KennethLavrsen - 17 Jun 2008

I simply copied the missing functions from from TWikiJavascripts/twiki_edit.js as I found it too risky to always include twiki_edit.js. If someone wants a more elegant solution then go ahead but this bug has been open since April 10 and it was a release blocker for 4.2.1. At least with this the constant errors at the bottom of the browser are gone. Confirmed in IE and FF3. twiki_tiny.js is just re-compressed by build script and only a few spaces are the difference.

I have tested that the mandatory form fields are still checked and that you can cancel out also without mandatory form fields being populated.

Tested in IE and the new FF3.
