Calendar portlet navigation problem

[claytonc]

BUG/PROBLEM REPORT (OR OTHER COMMON ISSUE)

What I did:

1. added a folder in the site, for example "Folder 1";
2. added a calendar portlet inside the folder created;
3. view the portlet in the site, hit the button for next month and back month.

Adding a calendar portlet to the root of the site works well.

What I expect to happen:

Calendar portlet showing next or previous month

What actually happened:

KeyError: u'Cannot find object at path folder-1'

What version of Plone/ Addons I am using:

Plone 4.3.14 no addons.

The error occurs from the version of Plone 4.3.12 and using plone.portlets == 2.3.

Debugging I discovered that the error occurs because the path is being passed as string unicode:
u'/Plone/folder-1'. [1]

For example [2]:
context.restrictedTraverse(u'/Plone/folder-1') ==> *** KeyError: u '/'

I didn't fix because I don't know why did they use "decode()" at line 66.

Using "blame" it seems to be Python 3 support https://github.com/plone/plone.portlets/blame/2.3/plone/portlets/utils.py#L66. Maybe @davisagli can give us a hint here.

Confirmed.
Plone 5.0 is using plone.portlets 2.3.3 and branch 2.2.x. See plone/buildout.coredev#284.
We should do the same should happen on 4.3: it is currently using a newer plone.portlets than 5.0, which is of course silly. I will fix that.

Summary: you can fix this in individual projects by pinning plone.portlets = 2.2.3.
