iOS ConnectIQ saving settings causes property key to be erased

I am getting a "Key does not exist in Application Properties" error (I'm printing the caught exception error message on the screen) on my Vivoactive 4 device after saving settings for it in Connect IQ on iOS for a beta widget that I am developing. I am retrieving these properties via Properties.getValue.

The property keys are set in resources/properties.xml with default values of "0", and in resources-round-260x260/properties.xml with values of "20", "16", etc.

<properties>
  <property id="PropArcThickness" type="number">0</property>
  <property id="PropArcCircleRadius" type="number">0</property>
  <property id="PropHoursMinutes" type="number">0</property>
</properties>

I have a boolean setting for toggling a feature on/off. Whenever I toggle this in Settings in the Connect IQ app on iOS, press "Save" (saved successfully), and pop open the widget on my device I am seeing the error mentioned above.

What could be causing the property keys to be "erased", as in no longer exist from the widgets point of view?

When I upload a fresh beta version to the store, and sync it to my device via the Connect app, and open the widget after syncing (without changing settings) it loads just fine. So I'm thinking something is happening when the Connect IQ app is syncing settings with my device.

Do you have settings for the property that gets lost?

The settings themselves are persisted and retained, which is good. It only seems to be non-settings property keys that are being "erased" (and I put that in quotes due to lack of a better word to use for describing this).

Hi acrossthekyle, are the properties you are getting this exception for ones that have a <properties> tag but not a <settings> tag? It sounds like this is the case but want to confirm.

Hey Kyle,

That is correct. Here is a brief example of the setup:

/MyWidget
  /resources
    properties.xml
    settings.xml
    strings.xml
  /resources-round-218x218
    properties.xml
  /resources-round-240x240
    properties.xml
  ...
  /resources-round-416x416
    properties.xml
  /source
  monkey.jungle
 
// MyWidget/resources/properties.xml
<properties>
  <property id="SomeProperty" type="boolean">true</property>
  <property id="AnotherProperty" type="boolean">true</property>
  <property id="ThisProperty" type="float">0.0</property>
  <property id="ThatProperty" type="float">0.0</property>
</properties>

// MyWidget/resources/settings.xml
<settings>
  <setting propertyKey="@Properties.SomeProperty" title="@Strings.SettingsSomePropertyTitle">
    <settingConfig type="boolean" />
  </setting>
  <setting propertyKey="@Properties.AnotherProperty" title="@Strings.SettingsAnotherPropertyTitle">
    <settingConfig type="boolean" />
  </setting>
  <setting propertyKey="@Properties.ThisProperty" title="@Strings.SettingsThisPropertyTitle">
    <settingConfig type="numeric" required="true" errorMessage="@Strings.SettingsThisPropertyError" min="-90" max="90"/>
  </setting>
  <setting propertyKey="@Properties.ThatProperty" title="@Strings.SettingsThatPropertyTitle">
    <settingConfig type="numeric" required="true" errorMessage="@Strings.SettingsThatPropertyError" min="-90" max="90"/>
  </setting>
</settings>

// MyWidget/resources/strings.xml
<strings>
  <string id="SettingsSomePropertyTitle">Some Property</string>
  <string id="SettingsAnotherPropertyTitle">Another Property</string>
  <string id="SettingsThisPropertyTitle">This Property</string>
  <string id="SettingsThisPropertyError">This Property Error</string>
  <string id="SettingsThatPropertyTitle">That Property</string>
  <string id="SettingsThatPropertyError">That Property Error</string>
</strings>

// MyWidget/resources-round-240x240/properties.xml
<properties>
  <property id="SomeNonSettingProperty" type="number">20</property>
</properties>

// MyWidget/monkey.jungle
project.manifest = manifest.xml

base.lang.bul = i18n/bul
base.lang.ces = i18n/ces
...
base.lang.zsm = i18n/zsm

The SomeNonSettingProperty property is the one, in this example, that would be "erased" upon pressing Save in the Connect IQ Mobile app settings screen, which then throws the `Key does not exist in Application Properties` error.

Thanks for confirming. We are currently testing out a fix for this issue. I don't have a date for when the fix will go live, but it is a server side issue so it won't require any phone app updates.

0 acrossthekyle over 4 years ago in reply to Kyle.ConnectIQ

Awesome, thanks for the update! I have updated my code to do device width checks for the time being, and removed the device-size-specific properties files.

Hello! Do you have an updated timetable of if/when this will be fixed?

0 Kyle.ConnectIQ over 4 years ago in reply to acrossthekyle

It should be fixed now.

0 Alan.raceQs over 4 years ago in reply to Kyle.ConnectIQ

It would be helpful if you could indicate the version that contains the fix.

0 Kyle.ConnectIQ over 4 years ago in reply to Alan.raceQs

It was a server side issue, so no changes to the phone apps were required.
