Thanks for the patch. This is now fixed in CVS HEAD and Zope 2.6 branch.

This is because intSets aren't properly marked as ghost when first loaded from the ZODB, so their state never gets set. The following change should correct this:

SteveA suggested I mention the intSet in question is the one built from Components/BTree/intSet.c.

It looks like Toby (htrd) was the last person to edit this (between 2.5.1 and 2.6.0) so hopefully it'll be a quick fix that he can apply.

Here's the script

In Zope 2.6.0, intSets loose their values.
The attached script demonstrates this.

It should be noted that intSets saved to a ZODB under Zope 2.5.1 loose their values when loaded in Zope 2.6.0.

I don't know whether this 'loss of value' is persistent if the ZODB is then moved back to 2.5.1.

This means that Squishdot Sites imported into Zope 2.6 loose all their postings :-(
