-------------------------------------------------------------
I've looked into this and found the line in wookie-wrapper which causes Syntax:
parse error message.
64: eval("Widget.preferences.prefs."+key+"=pref");
It seems Safari can't handle evaluating for example
"Widget.preferences.prefs.1245=somevalue".
Edit:
It's not actually Safari's problem, we should not allow passing numeric value
for key or let it be widget developer's problem, because JavaScript actually
doesn't allow numeric variables.

> Reporter: Scott Wilson
>
> 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!
