I'm working on a ColdFusion site where data is stored in WDDX packets inside a database and it's a real pain. (I have no idea why the values aren't just stored in another table.)
I've not used WDDX before and the only documentation I can find about it seems quite old. So I'm curious if anyone still uses WDDX, and if so, what for?
I use it to store a bunch on query results and structs. It is useful because it can capture multiple tables in one operation. JSON is a more modern approach to what WDDX solves. If I had a choice I would pick JSON because of its greater interoperability.
The last time I used it was to serialize the form scope. Can't remember much about why I needed to, but that the form had many variations and to repopulate the fields I could deserialize the WDDX and all was well with the world.
Haven't used it in a while now.
