I cannot predict at compile-time what the name (or properties) of the class will be. I need to CREATE the class at runtime, AND add the properties to it. It seems, so far, that this is not possible.
However, what I'm doing sounds very similar to your project. It's not so much the sheer number of tables (although a few dozen) but the fact that the application allows the creation of new tables (so I need a new class) and columns (so the properties might change). I can easily have my app write new destinations to the config file for any new table created. I can even write the necessary CFCs to disk based upon schema changes within the app. But I cannot find a way to get the classes I need. All tables share the same foreign key column name, which is helpful. My idea is this...set up one class that has two properties - the foreign key and a second column. I would have one destination for each table, but all destinations will point to the same class. When my CFCs pull data, I will have them return the primary key along with all other data encoded (XML or something) into the second property. Then on the client side I can manage it by filling an ArrayCollection, then having a function that parses the actual columns and rows (from the second property) into a second ArrayCollection that my datagrid is actually bound to. Creates/updates would go in the reverse direction - placed into the second ArrayCollection and then processed up to the two-property format for the first one, at which point LCDS will take over. As I think through it, this should work.
