Multilevel expandable list - Filter Issue

I implemented the multilevel expandable list as follows.

Item 1  ->  sticky header (extends AbstractFlexibleItem implements IExpandable, IHeader)
   Item 1.1  -> sub header(extends AbstractFlexibleItem implements IExpandable)
     Item 1.1.1 -> sub item(extends AbstractFlexibleItem implements ISectionable, IFilterable)
     Item 1.1.2
Item 2
   Item 2.1
     Item 2.1.1
     Item 2.1.1

The above showed implementation works fine, but sometimes i got exceptions like follows while filtering the data.

 if (mAdapter.hasNewSearchText(newText)) {
            Log.d(TAG, "onQueryTextChange newText: " + newText);
            mAdapter.setSearchText(newText);
            // Fill and Filter mItems with your custom list and automatically animate the changes
            // Watch out! The original list must be a copy
            mAdapter.filterItems(new ArrayList<>(items), 100);
        }

I am unable to handle this exception. Please correct me if i implemented the expandable list in wrong way (I followed the sample application to implement this feature).

Flexible adapter version: eu.davidea:flexible-adapter:5.0.0-rc1

@antoantonyk, the filter for multilevel should work and is available in the snapshot version.

The Snapshot version (future rc2) is more advanced in terms of new features and fixed bugs from rc1, as you can see from issue 39. So it is more stable than rc1, but it can change often based on my ongoing development and of course can introduce new bugs!! Since it doesn’t require any action from your side, you will receive the update once the new one is published and your cache updated after 1 day normally.

I think you can say to Gradle to not update a specific library or you can add it as external lib to close the production build.

@antoantonyk, I think you should use the Snapshot version since I could have resolved that bug recently see #328. Also be sure to correctly implement equals() and hashCode() for each items.

Unfortunately, there’s missing filtering for the sub-sub items. So your subItem won’t be filtered in this version as well. I will add it soon.
