[BlueBream] [Zope-dev] getting size of zope.schema.List from a view in bluebream

[Adam GROSZER]

Hello,

<class class="persistent.list.PersistentList">
    <allow attributes="__getitem__ __getslice__ __len__ __iter__
                       __contains__ index count data" />
</class>

Should do it. (but beware I did not test!)

That is in zope.app.security/_protections.zcml

Might be that you'd need to include that package.
