Orocos vs Boost::UTF

Hi, I'am trying to use boost::UTF (unit test module) to test my orocos task. When I add an attribut or Property, I've get this error msg in the console:

Running 1 test case...
0.001 [ ERROR  ][TypeInfoName] Can not build Property of unknown_t.

*** No errors detected

When I use the same code, without the boost::UTF, in a main(), I've didn`t get the error warning. The number of this error in the shell is the same as the Attribute count

This is my class

This is the cpp file

TaskContext(name),

bool DualAxisConverter::startHook()

    return true;
}
 
}// Namesapce RCL

This is the test file:

    // Set log level more verbose than default,
    // such that we can see output :
    if ( log().getLogLevel() < Logger::Info ) {
        log().setLogLevel( Logger::Info );
        //log(Info) << argv[0] << " manually raises LogLevel to 'Info' (5). See also file 'orocos.log'."<<endlog();
    }
 
    log(Info) << "**** Creating the 'Hello' component ****" <<endlog();
 
    // Create the task:
    RCL::DualAxisConverter hello("Hello");
    // Create the activity which runs the task's engine:
    // 1: Priority
    // 0.5: Period (2Hz)
    // hello.engine(): is being executed.
    hello.setActivity( new PeriodicActivity(1, 0.5, hello.engine() ) );
 
    log(Info) << "**** Starting the 'Hello' component ****" <<endlog();
    // Start the component:
    hello.start();
    log(Info) << "****code Using the 'Hello' component    ****" <<endlog();
    // Do some 'client' calls :
    log(Info) << "**** Reading a Attibutes:            ****" <<endlog();
 
    Attribute<double> p = hello.attributes()->getAttribute<double>("DesPosition");
    assert( p.ready() );
    log(Info) << "     "<<p.getName() << " = " << p.get() <<endlog();
    log(Info) << "**** Starting the TaskBrowser       ****" <<endlog();
}

The Attribut is initiated with the right value because of the print.

This is the only thread I`ve found on UTF: http://www.kindyn.org.tirant.priorweb.be/forum/rtt/rtt-dev/bug-641-new-migrate-cppunit-boosttests-utf

When I define the variable, nothing change: ENABLE_TESTS=OFF and ENABLE_BOOST_TESTS=ON

Can someone help me
