After editing ikiwiki.setup, and running "ikiwiki --setup", the CGI script is successfully created. However, if I then click on "Edit Page" link, I see nothing in the browser and the following in the logs:

Can anyone decipher this for me? I spent some time with cpan earlier today downloading the latest version I could find of prerequisite modules such as HTML::Template and CGI::FormBuilder.

I have version 3.0401 of CGI::FormBuilder -- the latest from CPAN. If you are wondering about any other modules, the answer
|
|
is likely the same: the latest from CPAN. And you're right: the error string in question does not appear in CGI::FormBuilder. I found it in HTML::Template (version 2.8).

OK, so downgrading CGI::FormBuilder to 3.0302 makes the problem go away. I'll leave it to you to figure out whether the bug is in CGI::FormBuilder or in IkiWiki. --Steve

Maybee this bug should be renamed as "doesn't work with CGI::FormBuilder (3.04)." I get same error on FreeBSD.

For the curious, this new version of CGI::FormBuilder changes how it passes
|
|
some values to the HTML::Template template. In particular, FORM-SUBMIT used
|
|
to be just a string containing the buttons used to submit the form. With
|
|
the new version, it's an array of strings, one per button, and the template
|
|
needs to be written differently to deal with this. Oddly, the docs have not
|
|
been updated about this. In fact, from all I can tell, it's a bug, since
|
|
the array is not in the form that HTML::Template expects to receive it.
|
|
Here's a simple test case:
|
|
|
|
#!/usr/bin/perl
|
|
my @fields=qw(editcontent);
|
|
my @buttons=("Save", "Preview", "Cancel");
|
|
|
|
use CGI::FormBuilder;
|
|
my $form = CGI::FormBuilder->new(
|
|
fields => \@fields,
|
|
template => "foo.tmpl",
|
|
);
|
|
print $form->render(submit => \@buttons);
|
|
|
|
With this test case, it does not seem to be possible to write a foo.tmpl that
|
|
outputs the buttons using the FORM-SUBMIT template variable.
|
|
|
|
I was able to work around this bug by just not using FORM-SUBMIT in the
|
|
template, and hardcoding the buttons (since they never change anyway).
|
|
Nasty, but it should work. I haven't fully installed the new version of
|
|
CGI::FormBuilder to test it, and it's quite possible that other changes
|
|
in the new version cause other breakage. If you want to test the fix,
|
|
it's in svn now. --[[Joey]]
|
|
|
|
Now that the new version of formbuilder is in debian unstable, I'm using
|
|
ikiwiki with it, and, after fixing a bug or two more, I think it's all
|
|
working, so I'll call this bug [[bugs/done]]. --[[Joey]]
