Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.0, Flash Lite 4 |
In addition, this exception is thrown when:
- An actual parameter to a function or method could not be coerced to the formal parameter type.
- A value is assigned to a variable and cannot be coerced to the variable's type.
- The right side of the
is
orinstanceof
operator is not a valid type. - The
super
keyword is used illegally. - A property lookup results in more than one binding, and is therefore ambiguous.
- A method is invoked on an incompatible object. For example, a TypeError exception is thrown if a RegExp class method is "grafted" onto a generic object and then invoked.
