Robot Framework tests fail with Plone > 4.3.11

[hvelarde]

After upgrading to Plone 4.3.12 all Robot Framework tests started failing as hown in the following screenshot:

as it can be seen, there's a new required field being shown in the form that normally doesn't appear; this field came from a XML schema like this:

<field name="cover_layout" type="zope.schema.Text"
       form:omitted="z3c.form.interfaces.IForm:true
                     z3c.form.interfaces.IAddForm:true
                     z3c.form.interfaces.IEditForm:true">
    <description i18n:translate=""
      >The layout to be used to render groups and tiles</description>
    <title i18n:translate="">Cover Layout</title>
</field>

as it can be seen, this field should be omitted on z3c.form.interfaces.IAddForm but that's not happening and I don't know why.

it's important to note that this happens only while running tests; the field is normally hidden when accessing the add form in a browser.

IMO this field must be redefined as readonly instead of being hidden all over the place.

@davisagli @datakurre @mauritsvanrees any hints here on why this is happening?

[datakurre]

Would you be able to check if it works with earlier plone.autoform versions?

@datakurre you can check the problem from a plone.app.testing perspective in plone/plone.app.testing#39.

@datakurre I already did that with no luck; Plone 4.3.12 was using plone.autoform = 1.6.2 also and we saw the error there.

I also tried pinning z3c.form = 3.2.9 with no luck neither.
