\ref within \defgroup

Hello World,

I have a problem with \ref within a \defgroup

I define a group (in a /** \page)
\defgroup inR16 Events and Requests available since QUARTIS R16
@{
\ref _charact_1<br/>
\ref _charact_2<br/>
@}

_charact_1 is defined as follows:
\subsection _charact_1 Turn on/off characteristics
text
text
...

_charact_2 is similar, e.g. also a \subsection

I create a HTML documentation. I see both references in the module page 
as links with the \subsection titles. The module page has the following URL:
file:///J:/QUARTIS/_dev/SDK/Automation/Doc/html/group__in_r16.html

But when I click on one of the links, I get an error, because the URL is 
wrong:
j:/QUARTIS/_dev/SDK/Automation/doc/Events.txt.html#_charact_1
(no file:/// in front, completely wrong file: Events.txt is the origin 
file for the documentation)

Is \ref within a \defgroup not supported or is this simply a bug?

TIA and best regards
	Andreas
