There are widgets that will work *only* on the dash, and widgets that will work on chumby but *not* on the dash.
Sony has created some exclusive relationships for some widgets that means they will only be available on their device. We are prohibited from making those widgets available for other devices.
Conversely, there are some relationships that Sony has entered into that means that some widgets that available for the chumby are not available for the dash. Depending upon which site you used to configure the device (www.chumby.com or dash.chumby.com), you will see a different catalog. If a user adds a widget that will not play on the device, it can manifest in different ways, a process we're still improving - it may not show up at all, it may put up a "this widget is not available for this device".
In some cases, there may be some other issue going on - in the case you describe, I'll take a look and see if I can figure out the problem. However, I'm very limited in what I can do - even the devices *I* have that access the production system are as locked down as yours.
One question - does your widget use the _root._chumby_chumby_id or _root._chumby_user_id properties?
