Hi Gerry,

Could you have someone to check this bug? 
We find that if you create a miss call after Phone app is killed, you can repro this bug by tapping the miss call notification from notification bar. Detailed repro STR as follows:
1. Kill the Phone app;
2. Create a miss call;
3. Tap the miss call notification from the notification bar;
**Device will show a blank call log view and user can't switch between All/Missed tab, and, the tab is located in the dial pad.

Cooking up a patch, this is a regression of bug 1183727. We should always be calling NavBarManager.update() every time we call Navigation.show() but after bug 1183727 we don't. This was a side-effect of the hashchange event handler.

First attempt at a fix: I moved the code used to update panels after having displayed them from the NavBarManager to the Navigation object, now every time we call Navigation.show() we also ensure the relevant panel is populated correctly. This works but I still have to fix the unit-tests and adjust the code we lazy load. As we already knew we load code via LazyLoader which we immediately need at startup so there's no benefit in doing it this way. I'm cleaning it up in the process as the NavBarManager was one of the offenders, LazyLoader.load()ing stuff on the start-up path and then waiting on it.

OK, this turned out to be a larger patch than I had anticipated because the new navigation code was lacking unit-tests and there were still some leftovers from the old hash-based navigation code that I wanted to remove. Here's a rundown of the changes:

- Moved the remaining navigation logic from the NavBarManager to the Navigation object, this ensures that whenever we call Navigation.show() we also properly display/populate the relevant panel

- Removed the lazy-loading of the source files needed to display the various panel. Sources for all panel were loaded in the startup path so it was pointless (in fact detrimental) to not just put them in index.html. I did some quick performance testing and couldn't see any difference in responsiveness before/after but the overall startup time is down by a few 10s of ms.

- Removed unused/dead code

- Added unit-tests covering the Navigation object

- Removed the tests that did not apply anymore to the dialer.js source file

I've smoke-tested this on a device trying various corner-cases (e.g. contact activities, switching between panels) and it's looking good.

Whoops, just spotted an issue when creating/deleting contacts. Removing the review flag for now.

Things seem to be working fine now, after discussing with Francisco I realized I must had hit some actual contacts regression which weren't caused by my changes. I've left a hack we had in the old navigation code which forced the conctacts frame to go back to the #home panel and I'm not sure if it's needed anymore or not hence the f? for Francisco. The rest of the changes are as per comment 13.

As we commented yesterday, the problem mentioned above are contacts regressions that we will take care of.

Just had a quick look and lgtm, but I'm sure drs will have a deep look to this. Regarding reseting contacts to the list each time the tab is visited, seems like a safe play to me.

Excellent, glad to hear that. The two hacks I had in mind are this:

https://github.com/mozilla-b2g/gaia/pull/31641/files#diff-3eebe091b42b34f2666e654da408936bR20

... and this:

https://github.com/mozilla-b2g/gaia/pull/31641/files#diff-3eebe091b42b34f2666e654da408936bR73

Both of which were in the original navigation code and I've left them intact in my fix. They both look horribly clunky but I was too scared of regressing something if I removed them.

Looks good, just needs an additional test.

Thanks for the review, I've added the test and pushed again. Will merge once try is green.

As usual the TV integration tests were orange but there's little to be done about them. Re-triggering doesn't seem to help and they take forever to run.
