[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.

[Zope] Re: ZClasses and "title" property
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. I just don't know how I can set that in instance objects since it doesn't appear on the property sheet. Can I modify the addForm and add methods for the class to set it there? Do I need to make a custom view? What approach do most people take in this situation, using the built-in title or choosing a different name for a title-like property? 2) The tutorial in the Zope Developer's Guide instructs you to add a "title" property to CDClass (http://www.zope.org/Documentation/Guides/ZDG-HTML/ZDG.6.2.4.html). I haven't actually run through the tutorial exactly, but I assume from my experience that this won't actually work. Maybe this part of the guide should be changed to reflect this (as well as other sections that also use "title" as an example property). Thanks for the responses!
