I've just started to work with ZClasses. They are really cool. But I am running into some problems:

Make sure you read through the ZClasses tutorial. You may also want to check out Loren Stafford's propertysheets howto.

I added a folder to my ZClass. Let's say the folder contains images. Using the images from the folder in my ZClass methods works fine. But like all other ZClass "internals" (methods etc.) the folder (correctly speaking: its instance; or is there no seperate instance of the folder???) is invisible to the management interface.

To make a Folder show up in the ZClass instance, you should create it from the ZClass_add method. For example, if your ZClass is called Foo, in the method Foo_add, you could put a line: <dtml-call "manage_addFolder('MyFolder')"> Then, every instance will have a folder called MyFolder in it.

Is it possible to make a folder visible in the management interface so that a user can enter additional images? Same with dtml methods/documents ...

Same thing applies for DTML methods/documents. Check out KM|Net News if you want to see one way to provide default documents that the user can change. KMNN also provides a way for the user to revert to the default.

Is it true that the methods of a ZClass don't open a new property namespace for each instance? If I change the property of a method in one instance it seems to be globally changed.

Your properties should be stored on ZClass propertysheets. Then the properties can vary from instance to instance. Kevin
