[webkit-dev] initializing protected variable in a subclass

[Chris Fleizach]

I have added

protected:
     AccessibilityRole m_role;

to AccessibilityObject.h

I want to initialize that variable in subclasses of  
AccessibilityObject, like so

AccessibilityImageMapLink::AccessibilityImageMapLink()
     : m_role(WebCoreLinkRole)

but the compiler says


/Volumes/data/WebKit/WebCore/accessibility/ 
AccessibilityImageMapLink.cpp:48: error: class  
‘WebCore::AccessibilityImageMapLink’ does not have any field named  
‘m_role’

even though this works fine

AccessibilityImageMapLink::AccessibilityImageMapLink()
{
     m_role = WebCoreLinkRole;
}

any tips?

thanx
