Item10811: "FieldFactory" error breaks FormPlugin

This is a fork of Item10730, where it was assumed, that this bug was assumed to be a part of various problems with the debian packages, but as it seems, it is not!

I took the latest official foswiki tar.gz, installed it and only added FormPlugin. As soon, as I try to access a topic containing a form, e.g. System/FormPlugin, I get the browser error message:

Foswiki::Plugins::FormPlugin::Renderer::Html::FieldFactory : Could not create field of type text.

and an error in the apache2 error.log:

So as it seems that the foswiki debian packages are not the culprits, might it be, that there's something special about the perl environment?

The bug is present on 2 different machines running debian stable (lenny).

-- PhilippLeufke - 31 May 2011

Could you check if you have List::MoreUtils ?

-- ArthurClemens - 31 May 2011

Wow, that was easy. That did the trick!

apt-get install liblist-moreutils-perl

Regarding the debian packages: it seems, that this dependence doesn't get resolved, when SvenDowideit gets the packages built automatically...

But it seems, the dependency is also not listed in the plugin description?!

Thanks, Arthur

-- PhilippLeufke - 31 May 2011

I forgot to add it, or I assumed at the time that it was a standard module.

-- ArthurClemens - 31 May 2011

I have updated the plugin to version 2.0.2. This now lists the dependency.
