Is there a simple example of custom component in MDL Dart http://www.material-design-lite.pub using a data table or a list linked to a model changing over time?
I have the exception
Exception: Uncaught Error: RangeError: Index out of range: index should be less than 6: 6

My prestashop gives the following errors:

Can Anyone here see what the problem may be? And also, how to save it?
This problem is related to your 'productsbundle' module when a product is added to the customer's shopping cart.
I would suggest either to update this module to the latest version available or to disable it from your admin panel.
i am making an ajax call to the controller, i dont know wants going wrong and this error is coming.
can someone explain this error.

eleminate one and problem is solved.
In the onBootstrap of my Application's Module.php I have registered a function onErrors on the EVENT_DISPATCH and EVENT_DISPATCH_ERROR events. In any of my models if I throw a custom error, Zend will catch it for me and in the onErrors function and I can handle the error (show an error page, return an error message as json, etc). This works fine except when an error is thrown in a function that's being used by Smarty. In that case I do still end up in the onErrors, but McvEvent->exception is NULL and I get this error:
Fatal error: Uncaught exception 'Application\Exception\InternalServerErrorException' in

What's happening here? Why isn't Zend catching this error for me?
Dartium gave me this error when I load my app (dart version, not compiled js) into browser:
Uncaught Error: Error evaluating expression 'model["mode"]': EvalException: Can't assign to null: model
I can see the error is caused by some code like this:
<polymer-element name="outer-element">
<!-- some codes here -->
<inner-element mode="model['mode']"></inner-element>
</polymer-element>
Where the model is a Map, model['mode'] is String, and the mode is declared via #published String mode on <inner-element>. Also, model is declared on <outer-element> via #published Map model so I can pass some map to <outer-element> in another custom element using <outer-element model="{{some map}}">.
This error doesn't make the app crash, actually, it has no effect as far as I can see, but it's really annoying to see it. (I have this error since the beginning of my development!)
I go through the data flow, but cannot find the problem.
Any idea would be appreciated. Thanks.

I suspect it has to do with:
Binding initialization when model is null
see also the comment here:
Polymer template repeat has weird side effect
The binding initialization can lead to situations where Polymer assigns to null or to non-assignable expressions. Previously they tried to suppress this errors but have seen situations where this is actually a bug and the developer should be notified about it, so they changed the behavior that errors are not suppressed but printed.
They try to figure out a way to improve this experience but seems not too easy.
This is just how I interpret some posts I read, I don't have any additional infos.
Chapter_06 in AngularDart example
when I run it in Dartium, there are some error:
