Please describe the problem:
Distribution version: Windows XP SP2
doxygen version: 1.4.7

When insert set/get properties into a defined group, these properties document don't be produced .

interface IControl : IDispatch{
	/*!
		\defgroup SinglePropertyGroup IControl Single Property
	*/
	/*@{*/
	/*!
		\brief Send Control Command
		\param newVal Control Command
		\return
			S_OK: Successful \n
			S_FAIL: Failed \n
	*/
	[propput, id(1), helpstring("Send Control Command")] HRESULT Command([in] BYTE newVal);
	/*!
		\brief Get Control Command
		\param pVal Control Command
		\return
			S_OK: Successful \n
			S_FAIL: Failed \n
	*/
	[propget, id(1), helpstring("Get Control Command")] HRESULT Command([out, retval] BYTE* pVal);
	/*@}*/
	
	/*!
		\defgroup MutiplePropertyGroup IControl Mutiple Property
	*/
	/*@{*/
	/*!
		\brief Send Engine State
		\param newVal Engine State
		\return
			S_OK: Successful \n
			S_FAIL: Failed \n
	*/
	[propput, id(2), helpstring("Send Engine State")] HRESULT EngineState([in] BYTE newVal);
	/*!
		\brief Get Engine State
		\param pVal Engine State
		\return
			S_OK: Successful \n
			S_FAIL: Failed \n
	*/
	[propget, id(2), helpstring("Get Control Command")] HRESULT EngineState([out, retval] BYTE* pVal);
	/*@}*/
	
	/*!
		\defgroup SingleMethodGroup IControl Single Method
	*/
	/*@{*/
	/*!
		\brief Start Engine
		\return
			S_OK: Successful \n
			S_FAIL: Failed \n
	*/
	[id(3), helpstring("Start Engine")] HRESULT Start();
	/*!
		\brief Stop Engine
		\return
			S_OK: Successful \n
			S_FAIL: Failed \n
	*/
	[id(4), helpstring("Stop Engine")] HRESULT Stop();
	/*@}*/
};

The reason is that set/get properties have been supported in 1.4.7, but there are no MemberList corresponding with "Properties". So add 
MemberList decPropMembers;
MemberList docPropMembers;
into the groupdef.h(&.cpp), and it works.

Steps to reproduce:
1. 
2. 
3.

Does this happen every time?
