ColdFusion MX: Changed behavior: if the value parameter is not a WDDX packet, ColdFusion returns False. (In earlier releases, ColdFusion threw an error.) |

| Parameters
|
|
| Usage
This function processes a WDDX packet with a validating XML parser, which uses the WDDX Document Type Definition (DTD). To prevent CFWDDX deserialization errors, you can use this function to validate WDDX packets from unknown sources. |
