An parameter was added to defaultEventHandler() of SelectElement. So, WMLSelectElement should use the defaultEventHandler with 4 parameters. However, the new parameter is HTMLFormElement. It is difficult to set the HTMLFormElement in WMLSelectElement.cpp.
For now, I add NULL instead of the HTMLFormElement in order to prevent build break when wml is enabled. IMO, this issue should be fixed later.
