[Zope] Re: ZClasses and "title" property
I think the problem goes deeper than that. Zope 2.3x no longer allows the setting or creation of any property called "title" for new ZClasses. Period (At least, not in the same way it used to). Try it for yourself. If you follow the steps in the "ZClass Properties" How-to (http://www.zope.org/Members/lstaffor/zProperties), you'll find that Zope 2.3x gives a "The id 'title' is invalid--it is already in use" error when you try to create a property called "title". Fine, you say, it's already there by default, right? Finish out the How-To, setting all the proper permissions, modifying the addForm and the constructor to accomodate your other properties. Then try creating an instance of your new class and setting the 'title' property through the addForm. The title will not be set when you hit 'Add'. The field will remain empty... Of course, the How-To above worked just fine in 2.2.5. Doesn't work anymore. There is no longer any default place to set the title in a new ZClass and the title property cannot be set thru DTML. (Haven't tried it in Python yet) Is this a bug or am I missing something? ajl >> I guessed it was something like this, so this leads me to two followup >> questions. >> >> 1) I'd be happy to use the built-in title property assuming that it >> won't cause some kind of problem.

Re: [Zope] Upgrade woes and product import problems
It worked like a charm! Thanks for the tip! As you suggested, perhaps this sort of ZGlobals corruption checking should be built into the core... I'd also like to see some automatic garbage collection in the default stop script -- like removing the temporary data and pid files. I've modified mine to do this.

Re: [Zope] Upgrade woes and product import problems
Well, I figured out a kludge from the "How to backup Zope data base?" thread and from the rc shutdown script. Turns out I needed to remove the Data.fs.*, pcgi.soc, and *.pid files -- leaving ONLY Data.fs and a few others, like the FSSession directory. That got both 2.2.5 and 2.3b1 to start up with my data. Only problem is that all instances of the ZClass I had created in my product (which I named ArticleProduct, btw) are broken in 2.3b1. The product itself appears in the Product Management menu, but even instances of ZClasses within the product are broken. Re-importing ArticleProduct.zexp does no good... I still get that "append" AttributeError (see traceback below). Is this a bug w/ 2.3b1 or am I missing something? Any help? ajl > I'm trying to upgrade to 2.3.0b1 from 2.2.5b1...

[Zope] Upgrade woes and product import problems
I'm trying to upgrade to 2.3.0b1 from 2.2.5b1... I installed the new version (according to the ZopeInstall HowTo, just to be safe), which started fine. I then shutdown Zope (2.3.0b1), moved the default var/Data.fs* files to a backup directory, then copied my old Data.fs* files over. When I tried to re-start 2.3.0b1, nothing happened. No debug message either. So I put the default Data.fs* files back in and restarted successfully. Fine, I thought, the database files aren't all that necessary. All the work I'd done on the previous version had been exported to a .zexp product export file, which were all subclassed from your run-of-the-mill ZClasses (image, file, folder, object manager, ZCatalog aware) and used DTML for all methods. No PythonMethods, no FSSessions, etc. So I put the .zexp file into the "import" folder and tried to import the product from within Zope. I got this error: Error Type: AttributeError Error Value: append Traceback (innermost last): File /usr/local/zope/2-3/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/zope/2-3/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/2-3/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/zope/2-3/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope/2-3/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_importObject) File /usr/local/zope/2-3/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_importObject) File /usr/local/zope/2-3/lib/python/OFS/ObjectManager.py, line 542, in manage_importObject (Object: Traversable) File /usr/local/zope/2-3/lib/python/ZODB/ExportImport.py, line 208, in importFile AttributeError: (see above) Here's my questions: 1. Why are my old data files screwing up Zope 2.3.0b1? 2. Why can't I import my product? Note: I also tried this with 2.2.5b1 --> 2.2.5, same errors. Any insights?
