class ParamError( [code], [description], [extra] ) \ from Error( code, description, extra )
Incongruent paremeter error.
This error is generated when a function is called with insufficient parameters, or with parameters of the wrong types; this error may also be raised if the function determines the parameters not to be valid for other reasons (i.e. if the function requires not just a string as a parameter, but also a string of a minimum length).
This error usually indicates a problem in the script code. Normally, it is to be considered a runtime error that has to be resolved by fixing an incorrect script, which should pass correct parameter to the functions it calls.
