The ICEfaces Advanced Comps (ace) should support the use of the <icecore:singleSubmit> tag. Using the "icecore:singleSubmit" tag can be viewed as a nice convenience, an easier way to indicate that all components inside a region should adopt singleSubmit behaviour, without having to specify "singleSubmit=true" on each component individually.

In the case of the ace components, placing inside a <icecore:singleSubmit> region on the page should have the effect of setting all the ace components "singleSubmit" attributes to "true". This approach will ensure that the ace component behaviour inside a singleSubmit region will be identical to that when their "singleSubmit" attribute is set to true.

This will require:

1. A mechanism for the ace component renderers to know if they are inside a singleSubmit region, so they can set their singleSubmit attributes accordingly (if not already defined by the application).

2. A way to ensure that the ace component events do not trigger the default "icecore:singleSubmit" tag submit behaviour based on event bubbling.
