Question

I have a FragmentActivity this activity has a Fragment this Fragment consist from widgets and fragment which is defined in xml.

When I start the activity it crashes

10-19 13:27:57.470: E/AndroidRuntime(16701): android.view.InflateException: Binary XML file line #43: Error inflating class fragment

Is it posible to have nested fragments, or I can put fragments only in FragmentActivity?

EDIT:
this is xml of fragment which is located in FragmentActivity ViewPager

Programm crashes in this file on inflating

        <com.ssbs.sw.SWE.widget.SeekBarWidget
            android:id="@+id/pa_outlet_characteristics_trading_stocks"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:max="999999"
            android:text="@string/label_outlet_characteristics_trading_stocks" />

        <fragment
            android:id="@+id/pa_outlet_characteristics_spinners"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            class="com.ssbs.sw.SWE.pure.outlet.pages.characteristics.view.components.SpinnersFragment"
            tools:layout="@layout/pf_characteristics_custperday_spinner" />

        <com.ssbs.sw.SWE.widget.SpinnerWidget
            android:id="@+id/pa_outlet_characteristics_proximity_factor"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="?spinerBackground"
            widget:label="@string/label_outlet_characteristics_proximity_factor"
            widget:popupDialogTheme="@style/ActivityDialog"
            widget:spinnerTemplate="@layout/widget_spinner" />

With the support API I don’t know but normally it’s not possible to create nested fragment : you can create a fragment from another one, but this fragment will communicate only with the Activity that created the original fragment (if it’s not clear, tell me)

EDIT :

As for why it crashes, if it’s not a nested fragment, I don’t have a clue. Maybe you should try creating it and adding it to your layout programmatically
