calculator problems with Qt 5.6

[Timo Jyrinki]

I suspect this might be UITK problem so filing there too.

On xenial (ubuntu-touch/staging/ubuntu) + Qt 5.6 (https://wiki.ubuntu.com/Touch/QtTesting) I'm not seeing any numbers in calculator when typing them. There seem to be other problems too. It seems to work better with Qt 5.5 (stock xenial).

Qt 5.6 would be targeted to be used when the switch to xenial is made at some point in the future.

More information about Qt 5.6 at https://wiki.ubuntu.com/Touch/QtTesting

(importance High from perspective of migrating to xenial / Qt 5.6 based images at some point)

No change with Qt 5.6.1.

Do you have any console output while you typing numbers?

[Timo Jyrinki (timo-jyrinki)]

Yes, each key press produces:

file:///usr/share/click/preinstalled/com.ubuntu.calculator/2.0.233/share/qml/ubuntu-calculator-app.qml:134: TypeError: Cannot call method 'config' of undefined

Also line 203. mathJs.config({

So I guess it can't find mathJs or something?

Before that, when starting the application there is (among else):
file:///usr/share/click/preinstalled/com.ubuntu.calculator/2.0.233/share/qml/engine/math.js:2854: TypeError: Cannot assign to read-only property "constructor"

If I comment that line out, I'll get:
file:///usr/share/click/preinstalled/com.ubuntu.calculator/2.0.233/share/qml/engine/math.js:2856: TypeError: Cannot assign to read-only property "name"

then:
file:///usr/share/click/preinstalled/com.ubuntu.calculator/2.0.233/share/qml/engine/math.js:7032: TypeError: Cannot assign to read-only property "constructor"

There are also errors like file:///usr/share/click/preinstalled/com.ubuntu.calculator/2.0.233/share/qml/ui/Screen.qml:107: TypeError: Cannot call method 'format' of undefined and file:///usr/share/click/preinstalled/com.ubuntu.calculator/2.0.233/share/qml/ubuntu-calculator-app.qml:361: TypeError: Cannot read property 'dbId' of null

on startup.

Likely not UITK problem anymore, all known Qt 5.6 issues fixed.
