Hey @curry684 👋

Would be nice if you could spare some time to review this.

Thanks in advance.

Hey @ToshY, I was away on holiday last week. Why did you close the PR, is it wrong or irrelevant?

[ToshY]

Well, I intended to use the bundle for a longer period of time, but after a week of fiddling around with it I realised I don't need most of the functionality/complexitiy that the bundle provides. So I decided I no longer needed to use it and I just could write the minimal code needed to work with the js datatable library.

While the fix worked (tested manually), I'm not sure if this is relevant to other users as I'm guessing the majority is using the other adapters anyway. So if you still think it's relevant, it can be merged. For me however it has become irrelevant.

I'll merge it anyway if it's tested to be fixed, looks good anyway although the ArrayAdapter is formally unsupported and just for testing/prototyping (in most cases a custom AbstractAdapter is less work, faster and tons more memory efficient).
