Cause
This error occurs if the input refers to a method that does not exist.
If this error occurs against the signature of a method implementation during a schema file load, it indicates that the method was not declared in the JadeMethodDefinitions section of the schema file.
Action
Correct the method name, if it is incorrect. If the method name is correct but the method has not been defined, define it by using the JADE Class Browser in the JADE development environment or by using a schema file.
