Does anybody have a more detailed guide or code examples on using Magma than what is on the main Squeak Swiki? I am running into problems, at a very eary stage, and I am almost sure that these problems are caused because of my meager knowledge on how to use the framework. For example, all the collections held as attributes by classes that you intend to persist should be MagmaCollections? How does the fact of using Magma affect the code and development process? What are the most important things to keep in mind?
