ofxOpenNI drawMask() and drawPointCloud don't work

I’m using OpenNI version 1.5.4.0 and NITE version 1.5.2.21 and I’m on Ubuntu 12.04.
Still using OF 0.8.x
gameoverhack master branch

Most of the parts work, except for one: I can’t see the user masks.
The native OpenNI examples work: I can see user outlines in them. But from OpenFrameworks, I can’t seem to get a user mask.

For each user in my OpenFrameworks code, I can do this:

// "user" is an object returned from ofxOpenNI::getTrackedUser

// This actually displays a skeleton:
user.drawSkeleton();
// These two do nothing:
user.drawMask();
user.drawPointCloud();

I tryed this also, but same result:

void testApp::setup() {
    //ofBackground(0,0,0);
    ofSetLogLevel(OF_LOG_VERBOSE);
    openNIDevice.setup();

    openNIDevice.addDepthGenerator();
    openNIDevice.addUserGenerator();
    ofSetFrameRate(15);
   
    openNIDevice.addImageGenerator();

    openNIDevice.setRegister(true);
    openNIDevice.setMirror(true);
    openNIDevice.setMaxUsers(2);
    openNIDevice.setMaxNumUsers(2);
    openNIDevice.setMaxUsersVis(2);

    //openNIDevice.setSkeletonProfile(XN_SKEL_PROFILE_NONE);
    user = new ofxOpenNIUser();

    (*user).setUseMaskTexture(true);
    (*user).setUseMaskPixels(true);
    (*user).setMaskPixelFormat(OF_PIXELS_RGB);
    (*user).setUsePointCloud(true);
    (*user).setPointCloudDrawSize(2);
    (*user).setPointCloudResolution(2);
    openNIDevice.setBaseUserClass(*user);

where user is defined in the .h file as ofxOpenNI *user;

In the update I do the following

void testApp::update()
{
   openNIDevice.update();


   openNIDevice.setMaxUsersVis(2);
   .....//nothing special
}

draw:

void testApp::draw(){

// use a blend mode so we can see 'through' the mask(s)
ofEnableBlendMode(OF_BLENDMODE_ALPHA);



//openNIDevice.drawDepth(0, 0);
//openNIDevice.drawImage(640, 0);


int numUsers = openNIDevice.getNumTrackedUsers();

for (int i = 0; i < numUsers; i++){

    // get a reference to this user

    ofxOpenNIUser & user2 = openNIDevice.getTrackedUser(i);
    user = static_cast<ofxOpenNIUser*>(&user2);

    // draw the mask texture for this user
    user->drawMask();
}

 ofDisableBlendMode();

}

Thanks so much in advance

I tryed the UserandCloudSimple example, it works like a charm, but if I run the UserAndCloudMedium it freezes like my example. The last example use the drawMask() method.

The error is as follows:

[error]: ofxOpenNIDevice[0]: g_DepthMD.XRes() 640 g_ImageD.XRes() 640

I handle to avoid the error by doing the following within draw(), however, nothing is displayed.

        ofxOpenNIUser & user2 = openNIDevice.getTrackedUser(i);
        user2.setMaskPixelFormat(OF_PIXELS_MONO);
        
        // draw the mask texture for this user
        user2.drawMask();

I am clueless at all, any hint? Thanks
