Description

I attached a quickstart with a test in TestHomePage#formSubmitsSuccessfully.

The test throws "'NEW VALUE' is not a valid Serializable" error when "NEW VALUE" string in "value" textField is submitted as a part of myForm ajax submission.

The problem is that a call to Objects#convertValue(nonNullNonArrayValue, Object.class) will always return null if nonNullNonArrayValue is a value that is not null and not an array! Shouldn't it always return the first parameter when the second parameter is Object.class?

Sven on Wicket forum suggested to fix this as by adding another if-statement in Objects#convertValue() if (toType.isInstance(value)) {
result = toType.cast(value);
}
