Dynamic Mode addData() not working , Throwing Null Pointer Exception

[ankesh4040]

In my HashTag view I am trying to dynamically add item. But doing so throws null pointer exception. Instead of addItem() if I use removeItem() {at same place} then there is no exception and the method returns true/false as result. Only issue is while using addItem(Object T) method.

Please help me with this urgently. Thanks

I have exactly the same problem. If I use the following code line from the example it is working correctly: hashtagView3.setData(DATA, Transformers.HASH);

[psincraian]

I have the same problem. It seems the problem is in line 238 of file HashtagView.java.

The problem is that viewMap is null.

public <T> boolean addItem(@NonNull T item) {
[...]
        if (viewMap.values().contains(itemData)) return false;
[...]
