Description

If you create a widget that uses numeric keys for preference values, this can cause a Parse Error deeper in Wookie (most likely, in DWR) even if the values are cast to a String.

To replicate, add this line to any widget:

widget.preferences.setItem("12345","67890");

Also:

widget.preferences.setItem("12345a","67890");

...will fail, but not:

widget.preferences.setItem("a12345","67890");

I suspect this is something either in the wrapper.js or DWR engine.js. Unfortunately the debug tools in Safari aren't sufficient to trace it properly.

As a workaround - just don't use numbers for preference keys!
