      Suspect two things.

      1. staledata_t* what is this type ? DataMngr.getInstance(root.dataTag) returning an QObject. Did you register the return type to be known to QML ?
      2. DataMngr.getInstance(root.dataTag) instance may not be returning anything. This may be null. Please check this.
      3. Any issue with DMngrSingleton this object creation ? Where is it created ? Did you check with debug statements?
