Error when editing page

Here is the error when I try to edit a page (clicked edit on a page, even without making any changes clicked save). It is very cryptic to me. Any idea what it means?

Traceback (innermost last):

Which version of is this?
How to reproduce?


Version Overview
Plone 5.0.8 (5018)
CMF 2.2.10
Zope 2.13.26
Python 2.7.6 (default, Oct 26 2016, 20:30:19) [GCC 4.8.4]
PIL 3.3.0 (Pillow)

Content-types ( 1.2.17

Very easy to reproduce (in my instance at least)... click on a page that is not published. Click edit, make changes/or not, then click save.

Can not find a call to unicode here

Please re-verify.

That's what it said in the quickinstaller. 1.2.17
There was a 1.2.23 available so I upgraded it. Tried to edit the page. Same result.

I think I found the issue.

obj.Subject() should actually be obj.Subject

That is without parentheses. Subject is actually a string.

TESTED: yes, that was it.

err, no. If you actually changed the Plone code like this, it can't be correct. Subject is really a tuple. If in this case it is a string, it is a problem elsewhere. For the record this is working fine on a vanilla 5.08 version. Rather than changing the code like that, try to add something like:


just before subject=
and rerun Plone in debug mode (fg) to understand what is happening here to see what is displayed immediately before the trace.

I'll try that, thank you.

small typo in my post, Subject() is (of course) a method returning a tuple. This is clear from the code. So something is wrong in your install. Is it the result of migration ? is there add-ons ?

Nothin that I can point to. However, I am pulling data from an older plone instance and putting it in this one. I have to take a better look at my code to see how subject is special.

that should explain it then. It's very easy to put a string instead of an object in the Zodb and it can appear to work. However it will bites you at some time or another. The subject may seem just a text field where a string with carriage returns inside will fit, but it's not.

So now that I change subject to a tuple the same line in returns: TypeError: 'tuple' object is not callable.

Help :frowning:

I said that it's not a string, I did not say it was a tuple, it is an object that is managing several lines.

that was not a success, in fact Subject is not the 'summary' in the UI, it's the tags so
let's try again

ouch !

it seems that Subject should be set with a tuple and the method setSubject, and the summary (Description in the API) using a string with CR/LF
This is looking fine in the UI.
Ah, don't forget to call reindexObject when all is done.
