Unhandled exception on instantiating ToggleMenuItem

I am getting an unhandled exception (and crash) on this call, on a Tactix Delta, FW version 26.00

var showData=false; // defined as a global

$.showData=Application.Properties.getValue("ShDat");

var ma=new WatchUi.ToggleMenuItem("test item", "abc def", 4, $.showData, {} );

I can't figure out what it is complaining about.

Another thing that is happening on this watch is that the ShDat boolean <property> which was clearly initialized as false in the properties.xml starts off as true when the app first installed and loaded.

I also suspected that the ShDat property was null, so I tried adding code that set $.showData to false if a null was read, but that did not solve the problem.

The simulator, and other watch models (so far) don't exhibit this problem.

There are two cases where the getValue() case for Application.Properties will throw an exception:

Throws:

(Lang.UnexpectedTypeException) —

Thrown if key is a disallowed data type
(Properties.InvalidKeyException) —

Thrown if key does not exist in Application Settings

Use a try/catch with a default value set in the catch. from your code, I'd guess your settings got lost and you are seeing the second case.People have reported an issue with the settings getting lost in the past.

Thanks useful info, but that line is not throwing an exception the line

var ma=new WatchUi.ToggleMenuItem("test item", "abc def", 4, $.showData, {} );

is the one which is.
