Hello everyone,
I have request for solving problem regarding company's Plone page, I haven't work on this site for a very long time so I am still going around this to get myself familiar with everything, maybe this error traceback will tell You more than me, so if You have any directions to point me on solving this, please do help me...
On navigation to a certain page which shows some documents we get following error:
(Other pages in same folder show contents without problems)

Traceback (innermost last):

A NameError usually indicates a programming error.

In your case, look at line 46 of ... ucts\CMFPlone\skins\plone_content\folder_tabular_view.pt. You should see there something like tal:condition="item_icon/url". Add | nothung before the closing ".

This should in fact be "Add | nothing (not nothung).

Hello Mr. Maurer,
Thank You for answering,
I changed 46.line into:
tal:condition="Add | nothing"
And it worked, now content is shown as it should. Should I leave this line like this or?
Regards

As I wrote, NameError indicates a programming error. As the affected template belongs to Plone itself (i.e. it is fairly often used), there is something special in your site which "triggers" this error while it typically is masked.

You have various options:

  • report the error in Plone's bug tracker. This increases the chance that the error is fixed in future releases. Otherwise, the error may resurface when you make a Plone upgrade (but you know then how to fix it)

  • try to understand what speciality "triggered" the error and remove it. If you succeed (which is not sure), then you may live with unmodified Plone code.

  • try to upgrade to a newer Plone version. Maybe, the error is fixed there.

  • use jbot ("Just another Bunch Of Templates") (the complete package name has a prefix (maybe collective, but I forgot the details) to use a fixed template beside the buggy Plone one.

I do not know which option is the best adapted for you.

Some options can be combined: thus, you can report the bug in any case.
