hi i have a python class which inherits from ObjectManager and OrderSupport now my manage_main should display the order support stuff, but it doesn't anymore on my development machine since i upgraded to zope 2.7.0 final and python 2.3.3 here the debug info of my devel machine:: Debug Information * Zope version: (unreleased version, python 2.3.3, linux2) * Python version: 2.3.3 (#1, Jan 29 2004, 07:54:24) [GCC 3.2.3 20030422 (Gentoo Linux 1.4 3.2.3-r3, propolice)] * System Platform: linux2 * SOFTWARE_HOME: /opt/zope/270/lib/python * INSTANCE_HOME: /home/bd/zopes/first * CLIENT_HOME: /home/bd/zopes/first/var * Process ID: 5846 (49156) * Running for: 1 min 32 sec * sys.path: /home/bd/zopes/first/lib/python /opt/zope/270/lib/python/Zope/Startup /opt/zope/270/lib/python /usr/lib/python23.zip /usr/lib/python2.3 /usr/lib/python2.3/plat-linux2 /usr/lib/python2.3/lib-tk /usr/lib/python2.3/lib-dynload /usr/lib/python2.3/site-packages /usr/lib/python2.3/site-packages/PIL /usr/lib/portage/pym * Top Refcounts: on the production machine it works, this machine uses python 2.3.2 and zope 2.7 beta 3 when i copy over OFS/dtml/main.dtml to my products directory and define manage_main directly in my class like this:: manage_main = DTMLFile("dtml/management/main",globals()) it works just fine, without changing anythong in main.dtml one last info: the class is just a base class for a few other classes which s objects are then added to the zope instance tia, bernd
