Exactly why this happens is hard to say, but it happens very often where you have many modules that are dependent on each other. Refresh basically is a bit of a pain to use on any module who contains some sort of "core" functionality that other modules use. In principal you need to refresh every module that uses the module that was refreshed, and all modules that uses these modules. In the right order. Quite often, no matter what you try, it will fail. In that case: restart. The best way to avoid refresh-problems when debugging is to actually use unit test, and thus avoid the whole issue... -- Lennart Regebro, Nuxeo http://www.nuxeo.com/ CPS Content Management http://www.cps-project.org/ ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

[Zope] symbols undefined after product refresh?
hi! after reloading my own products through the zmi it seems like some classes and methods gets undefined. please see the following traceback: ... Module Python expression "here.zuml_parseAndCheckinModel(newConfigDict)", line 1, in Module Products.IDE.IDEContainer, line 176, in zuml_parseAndCheckinModel Module Products.Relateable.MetaManager, line 474, in recreateIndexes Module None, line 104, in addSubClassCatalogMethod TypeError: 'NoneType' object is not callable the code @ line 104 is: o = SubClassCatalog(id, searchKeys, subClassNames) SubClassCatalog is defined in /Products/SubClassCatalog/SubClassCatalog.py, after I refresh the Product "SubCLassCatalog", i get the error mentioned above. restarting Zope fixes the Problem, MetaManager::recreatedIndexes() will work repeatedly until i refresh one or more Products... did i miss something while importing stuff? /Products/relateable/MetaManager.py imports the constructor for a SubClassCatalog like this: from Products.SubClassCatalog.SubClassCatalog import addSubClassCatalogMethod i'm pretty puzzled at this point, hope someone got a hint... regards, juergen herrmann ps: this does not only happen to my SubClassCatalog, this also hits f.ex. "from random import randint" where randint gets undefined. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
