Attributes Attribute dataSource tableName Req/Opt Required Required Default Description Name of the data source that contains the table.

The WDDX is an XML vocabulary for describing complex data structures in a standard, generic way. Implementing it lets you use the HTTP protocol to such information among application server platforms, application servers, and browsers. This tag generates JavaScript statements to instantiate JavaScript objects equivalent to the contents of a WDDX packet or CFML data structure.
