Android - Fragment is null after Picture Intent (REQUEST_PICTURE_CAPTURE)

I have an app which has a PagerAdapter with a few Fragments. From the main activity, I start a REQUEST_PICTURE_CAPTURE intent, it works ok, when it ends it calls onActivityResult(). In onActivityResult(), I have simple code:

m_PagerAdapter.GetTheFrag().DoStuff(..., ...);

Where m_PagerAdapter = derived from a PagerAdapter,

GetTheFrag() = // returns the derived Fragment object, which wasn't null before starting the Intent. This is the problem,

DoStuff() ==> never gets called, because m_PagerAdapter.GetTheFrag() is null .

The weird thing is that sometimes it does work and sometimes not, doesn't matter what picture quality or any capture related properties.

// In PagerAdapter
public MyFrag GetTheFrag() {
    return m_MyFrag;
}

// In PagerAdapter
private View getViewByID(Integer integerID) {
    switch (integerID) {
        case R.layout.my_frag:
            if (m_MyFrag == null) {
                m_MyFrag = new MyFrag(m_MainActivity);
            }
            return m_MyFrag.GetMyFragView();
    }
    return null;
}

// In MyFrag
public View GetMyFragView() {
    return m_ThisView;
}
