Hi! OK, it looks like I've been doing things a stupid way by not using ZCatalog. I managed to find a ZCatalog.txt buried deep within the source, but I'm a bit stuck now. First. I created a ZClass in my own Application with my Events class. Do I need to delete it and recreate it so that it lists ClassAware as one of its meta types? When a class is ClassAware, how does it know into which catalog new items should go? I haven't been able to make the thing update catalogs automatically. What is the purpose of using the Contents tab of a ZCatalog to actually add items inside it? What are the pros/cons of doing this? Why are these objects not automatically cataloged? Where can I find a reference on the syntax of searching a catalog? Thanks, John
