Infinite mode getNextPage resets the collection

[ristovskiv]

In infinite mode on collection.getNextPage instead of models being add to the collection, the collection resets with the models from the current page.

Here is my collection code.

class LoopCampaigns.Collections.MailTemplates extends Backbone.PageableCollection

  url: "/api/mail_templates"

  mode: 'infinite'

  state:
   pageSize: 10

  model: LoopCampaigns.Models.MailTemplate

  parseRecords: (response)->
    return response['mail_templates']

  parseLinks: (response)->
    return {next: response.links.next, first: response.links.first, prev: response.links.prev, total_entries: response.links.total_entries}

here is a preview from the json response from my Rails API

{
"mail_templates": [
{...},
{...},
{...},
{...},
{...},
{...},
{...},
{...},
{...},
{...}
],
"links": {
"first": "/api/mail_templates?page=1",
"next": "/api/mail_templates?page=2",
"prev": "/api/mail_templates?page=0",
"total_entries": 16
}
}

In infinite mode, there's a fullCollection inside your collection which serves as a container for the already fetched models, but only the current page is in the collection models array.

If you're after infinite scroll or something akin to this, without a need for paging, I made an infinite collection inspired by the API of this lib.

@wyuenho I experienced the same issue. Any other clues?

@turkus Backbone.paginator is not meant to be used this way and the pagination behavior is too deeply ingrained in the collection to work around it. You'd better be implementing your own collection. See issue #344
