filter feature broke after hitting no result

[ashi009]

How to reproduce

1. Go to https://saulis.github.io/iron-data-table/demo/filtering.html
2. Scroll down the list (optional, but it will break for different reasons.)
3. Input "ttttt"
4. Now the iront-data-table is broken.

I didn't look too deep into this, and here are my findings:

• _loadPage() tries to load page 1 from the array datasource.
• array-datasource.js will filter the items, and call the cb() (sucess() from _loadPage()) with an empty array when there is no match.
• _loadPage() will iterate through this empty array with out of boundary indices then fill undefined to this.set('_cachedItems.' + index, item).
• iron-list will break by these undefined items.

Thanks for the report!

There seems to be a check that fails when the returned size is falsey, can you try out if the branch fix/filter-zero-size fixes all the issues for you?

Thanks for the quick fix!

I've created a demo at http://jsbin.com/zisojebuge/edit?html,output, and it looks good!

Scratch that. I might have tested with wrong branch. Let me apply the patch to my project and see.

Yep, this fixed the issue!
