md-chips + md-autocomplete: suggestions not shown after all items added & removed

[sebastianhomeier]

Actual behavior:

• What is the issue?

In my example (https://jsfiddle.net/vv18yjzo/7/) the autocomplete suggestions should be shown, as long as the md-chips input is focused. This works well when I enter a few items. However, when all available items are added and then removed, the autocomplete suggestions are empty / hidden. I have to enter a new search text to see the autocomplete suggestions again.

• What is the expected behavior?

The md-autocomplete suggestions should be shown when no items are selected (= the chips input is empty) and the md-chips input is focused.

I narrowed my problem down to the value of searchText. If an item gets removed and searchText is an empty string, you can simple set searchText equal to null. Afterwards, vm.searchCategories() in md-items="item in vm.searchCategories()"of the md-autocomplete directive gets called:

vm.onCategoryRemoved = function($chip, $index) {
    if(!vm.autocomplete.searchText) {
        vm.autocomplete.searchText = null;
    }
};

Despite, it would be great to have a built-in solution for showing the suggestions everytime the md-chips input element is focused.

I think this may actually be related to #7655 which I'm investigating right now. I will keep you updated if I find that it's related.
