Incorrect warning about two-way bind on v-for alias with filters not working. #1778
Description
In Vue 1.0.x there is a new warning issued for attempting to write to a v-for alias when using a filter, warning that it will not work correctly. This warning goes off even when you follow the advice given and bind against object parameters, and more confusingly, if the alias appears anywhere in the expression, even if it not being written to at all.
Warning on reading value from v-for alias:
[Vue warn]: It seems you are using two-way binding on a v-for alias (items[item.id].name), and the v-for has filters. This will not work properly. Either remove the filters or use an array of objects and bind to object properties instead.
