[Zope] ZClasses and properties

[Oscar Picasso]

Thanks for your help. It works fine using the first solution. I tried the
second that seemed to better fit  my needs. But I'm unable to add a new
photo in an instance. Here is what I've done:

Product at /Control_Panel/Products/MZProduct  
    MZClass      #my main class 
    MZClass_add (MZClass constructor)  
    MZClass_addForm (MZClass constructor input form)  
    MZClass_add_permission (MZClass constructor permission)  
    MZClass_factory (MZClass factory)  
    MZPhoto_add_permission (MZPhoto constructor permission)  

Z Class at /Control_Panel/Products/MZProduct/MZClass  
#in the view tab
    Contents    manage_main 
    Properties  propertysheets/mz_info/manage 
    Add Photo   MZPhoto_addForm 
    
Z Class at /Control_Panel/Products/MZProduct/MZClass  
#in the methods tab
    MZPhoto  
    MZPhoto_add (MZPhoto constructor)  
    MZPhoto_addForm (MZPhoto constructor input form)  
    MZPhoto_factory (MZPhoto factory)  

When I view an instance I see the three tabs:
Contents, Properties, Add Photo.

If I go to Add Photo tab and enter and id. I get the following message:
Error Type: TypeError
Error Value: argument title was ommitted

What's wrong with my classes? 

>You need to subclass Object Manager when you generate the ZClass. Than
>you can add other objects into the instances. If you only want to add
>photos, build another ZClass in your class, which represents exactly
>a photo object (subclass from file or image) with all the needed
>properties filled during upload.
