Re: project based pier

PRStructure and subclasses is the model for the hierarchical structure of Pier. If your model is anything beyond the simple hierarchal folder and file structure of Pier, I wouldn't implement it as a subclass of PRStructure. For example, when you have the typical and highly interconnected University, Student, Professor, Course, Exam kind of model; I would implement all these classes separately from Pier. And then you have different structure subclasses that delegate to your complex domain model. So you'd probably had a - a university structure that would delegate to one University - a person structure, that would delegate to one Student or Professor - a course structure, that would delegate to one Course and the exams in that course Does that make sense? Another alternative is that you do not work with PRStructures at all, for example if you don't need the URLs. Then you can simply create your own model and your own plain Seaside app and embed it into Pier at some place (or use it independently from Pier). Lukas -- Lukas Renggli http://www.lukas-renggli.ch
