[ZPatterns] access denied error

[Joachim Schmitz]

More Information:

I exported the old and new ZClasses in xml-Format and did a

diff old new

besides the many differences in the keys string ids, I found only this
suspicious one:

139,145c139,144
<         <global id="48735.1" name="ExtensionClass" module="ExtensionClass"/>
<         <tuple id="48735.83">
<           <string id="48735.2" encoding="repr">RE</string>
<           <tuple id="48735.6">
<             <global id="48735.3" name="PersistentClass" module="ZClasses.ZClass"/>
<             <global id="48735.4" name="DataSkin" module="Products.ZPatterns.DataSkins"/$
<             <global id="48735.5" name="SimpleItem" module="OFS.SimpleItem"/>

147c146
<           <dictionary id="48735.7">

So the working old ZClass has something to do with OFS.SimpleItem, and the
new not working not.
