Error when populating listview dynamically (via Internet). Sectionizer tries to sectionize list rows when none of the list items are loaded yet. #18

Please help me out. TIA :)

If I sectionize ONLY after the entire listview is populated dynamically, then the library gives me an error :

Caused by: java.lang.NullPointerException: sectionizer cannot be null! Did you remember to call setSectionizer() or setMultipleSectionizer()?

If I sectionize before the listview is populated dynamically with a random temporary value and resectionize after the listview is populated dynamically , then too I get the error :

Caused by: java.lang.ArrayIndexOutOfBoundsException: length=0; index=0 at com.nolanlawson.supersaiyan.SectionedListAdapter.isEnabled(SectionedListAdapter.java:260) at com.felipecsl.quickreturn.library.widget.QuickReturnAdapter.isEnabled(QuickReturnAdapter.java:42) at android.widget.ListView.lookForSelectablePosition(ListView.java:2041) at android.widget.ListView.setAdapter(ListView.java:499) at akshapps.testinglistview.MainActivity.onCreate(MainActivity.java:126)

Sorry, I don't really remember this library very well, nor was I wise enough to write tests for it. :/ Maybe the issue is that you can only sectionize once? I'm pretty sure I don't allow you to dynamically resectionize. I.e. you can only call setSectionizer() once IIRC. Sorry I can't provide many more details than that.
