This problem occurs in a project that works perfectly with ZOPE 2.6.
After the upgrade to ZOPE 2.7.4 the user is asked for permission when
ZClass code references a property defined in a property sheet.
More detailed: A tal command of a ZPT inside a ZClass tries to access a
property that is defined in a property sheet of the same ZClass, but is
- of course - given a value in the instance of the class. In ZOPE 2.7.4
the user is asked to authenticate, and if he cancels authentication he
gets the message:
"Error > Value: You are not allowed to access 'teillisten_laenge' in
this context".
where teillisten_laenge is the property in question. This is just one
example - the problem seems to occur in all similar cases.
Here's the code fragment that tries to read the value of teillisten_laenge:
<span tal:define="listen_laenge
here/propertysheets/listenstil/teillisten_laenge">
<span tal:define="sort_kriterium string:id">
...
</span>
</span>
Someone confronted with the same problem? Seems to be a bug, or could it
be wanted behaviour? Any proposals for a workaround?
Thanks,
Uli
