HI Charlie, In response to the new test for 10.8.f, I mentioned there would be problems with this test, 10.8.e. In DOM2 the term "cancelable" refers only to whether or not the default action of the event is cancelable. The ability, or lack thereof, to stop the propagation of the event is never in question. One can say whether or not the event bubbles when it is dispatch, and one can *always* stop the propagation. It is possible to test the ability to stop the propagation, which is what I incorrectly asked for. It seems to be the only thing, though, that we could reliably write a cross-implementation test for. A custom event does not have a default action whose behavior we know about beforehand, so how can we write a standard test to detect whether or not its default action was cancelled? There are a few possibilities: 1) Throw out the test 2) Relabel the test to say that it is testing the ability to stop the propagation of a custom event 3) Add a feature to query the state of an event, then use it Clearly, #3 is out for 1.1. #1 is a bit of a headache, and #2 is at least doable (as you've shown). Of course, none of this even covers the perceived holes in the testing framework, such as whether bubbles=false or cancelable=false work? Thoughts? John M.

The ev:event attribute was placed on the model element, not on the action element that shows the message proving that the event was dispatched. So, the test requires that one should *not* see a message for the custom-event, but the reason you don't see it is that the event attributes are incorrect. The ev:event attribute needs to be attached to the action element within the model. The model also has no instance, which is required, so I would not expect this form to work. However, we already have a test 10.8.d that tests dispatching a custom event. This test purports to test a cancelled event, i.e. one with a and ev:defaultAction of cancel. However, the test assumes that cancelling the default action would cause the event bubble phase not to happen. The test needs to use stopPropagation instead. Then, another action handler needs to be added to observe the parent of the event target instead. So, I think this test should change by 1) adding an instance with an ID 2) targeting the custom event at the instance, not the model 3) attaching the ev:event and stopPropagation on the xforms action in the model. Then, we can claim that you shouldn't see the message. Thanks, John M.
