Help - plone 6.1 ConfigurationConflictError when a behavior is declared: Is configure.zcml being loaded twice?

Plone Support

Hi,

I declared my first behavior in behaviors/configure.zcml in Plone 6.1 classic:

<include package="plone.behavior" file="meta.zcml"/>
<plone:behavior
title="Megamenu Extra Image Field"
description="Adds an image field only to MegamenuColumnV2."
provides="por.intrasite.behaviors.megamenu_extra.IExtraMegamenuFields"
name="por.intrasite.behaviors.megamenu_extra.IExtraMegamenuFields"
/>

When I run bin/client fg, I get the following error:

File "/srv/data/por_site/eggs/Zope-5.12-py3.12.egg/Zope2/App/startup.py", line 41, in load_zcml

ChatGPT suggests that behaviors/configure.zcml is being loaded twice.

Here's what I've checked:

  • There is no duplication of por.intrasite in the eggs section of any .cfg file.
  • There are no explicit zcml entries in my .cfg files.
  • There are no recursive <include package...> directives involving por.intrasite.
  • No other packages have an <include package="por.intrasite"> directive.

In src/por.intrasite/setup.py, I have:

entry_points="""
[z3c.autoinclude.plugin]
target = plone

And por.intrasite is in the eggs list of the [buildout] section. ChatGPT suggested this might be the cause, but I don't believe it, as this is a standard setup for a Plone add-on.

Could you please provide some ideas on what might be causing this? Many thanks for your time.

try to change the name to something different, something like por.intrasite.megamenu_extra. More on behaviors:

A bit off topic, but behaviors can be added with plonecli

plonecli add behavior
