We should have a ViewManager component, which follows instantiable pattern and will be able to replace render.js.

WIP here to create ViewManager to replace render.js. Tim, if possible, please help give early feedback per this commit, https://github.com/RudyLu/gaia/commit/79cf6311e5196dbeda765890a4305ba82c14ee07 This is based on the previous work of view re-org, but it was not landed yet due to test issues. Thanks.

Comment on attachment 8547503 [details] Patch V1 Nice clean up. I wonder if you want to re-organize the APIs in this bug or in future bugs -- as we have discussed, the way IMERender works with controller logic doesn't make a lot of sense currently. This patch simply make ViewManager inherits that. BTW you have not remove the render.js from the tree, even though it's not build anymore.

I was working on a WIP patch to get the APIs saner, however, I think I should get this bug done first to unblock any potential changes to view related code. So create another bug to track the API re-org work, Bug 1122453.

Comment on attachment 8547503 [details] Patch V1 The review comments have been addressed and unit tests are ready (though, it seems gaia-try was not triggered). Tim, could you please help review it again? Thank you very much!

Comment on attachment 8547503 [details] Patch V1 The improvement of the APIs probably takes more than bug 1122453 to complete. This patch along provide a good foundation to work on those bugs although itself doesn't do a lot (other than enabling us to test separate ViewManager instances than re-testing the one-and-only IMERender). Let's land this first if there aren't known regressions.

Landed to Gaia master, https://github.com/mozilla-b2g/gaia/commit/78773e0ff21e257b5f6539781e15e05ba9cf1873 -- Thanks.
