zope220 working fine, redhat 6.2, intel hardware. Installed zope221b1 (tried installing the upgrade tar over a copy and compiling - repeated with the source tar - same results). All zclass instances broken - the zclass products are healthy looking in the Products folder and new instances added under 221b1 seem healthy - it's just all the existing ones which appear broken. Tried deleting and then importing fresh .zexp versions of the folders containing my zclass instance - the .zexp file imports fine but the contained instances are still all broken. Stopped futzing. Back to zope220 for now. Is it just me ? _______________________________________________ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
