810449 - [Trusted UI] Accessing an existing app process using a trusted UI through the task switcher opens up a blank homescreen

Status: VERIFIED FIXED

(Firefox OS Graveyard :: Gaia::System, defect)

Description

[Jason Smith [:jsmith]]

Attachment: Empty homescreen

Build:

Device - Unagi

Hashes

  <project name="gaia" path="gaia" remote="b2g" revision="319123f39aacfc98387390e1f173035f1870bacd"/>
  <project name="releases-mozilla-aurora" path="gecko" remote="mozilla" revision="48017631bc649ce43791db461d3a549ec51a27e3"/>

Steps:

1. Launch trusted UI with mozPay
2. Hit the home button
3. Open the task switcher
4. Go back to the process using the trusted UI currently

Expected:

The trusted UI for that process should open on top of the homescreen.

Actual:

A blank homescreen instead. The work-around is to hit the home button to get out of this state.

Btw - there is weird behavior that can happen if the work-around is done, as I hit a case with trusted UI ending up on top of another app.

blocking+ -- can't land on a blank screen without direction.

It feels like the homescreen does not have receive it's iframe.setVisible call.

Assigning to Tim, feel free to re-assign if you're too overloaded.

It seems that Alberto already fixed this on https://github.com/albertopq/gaia/commit/a033d4a2da61e412cb032dd32648b4e9acef7c09
Re-assigning to him.

I've never tried to invoke Trusted UI, and would like to know how to trigger it for testing!

Sorry, I didn't mean to set the blocking-basecamp flag to '?'. I am afraid that I can't set it back to '+'.
