You can store non-serializable data as persistent page properties or in the visit but you'll defeat clustering if you do so. Think in terms of reconstructing your data; so if you can't store a database object, store its primary key. If you can't store a connection pool, store its JNDI name, etc. Use synthetic properties, or just-in-time calculation, to go from the "seed" back to the full value. > > An other example question would be: is it possible to use more than one > class per Tapestry page in the .jwc (or .page :) specification tag? Not as such ... how would Tapestry know which class to use in which place? However, if you carefully read the docs, there's the concept of "helper beans". These are addtional JavaBeans you can instantiate and configure (with some control over their lifecyle). Often, reusable objects such as a validation delegate can be created as helper beans. ------------------------------------------------------- This sf.net email is sponsored by: Dice - The leading online job board for high-tech professionals.
