How to extend UIX2.1.7 to have set and compound event handler tags

I am using Jdev9033 now, but I want to know is it possible to extend uix2.1.7 myself to have set and compound event handler tags just like uix2.2.3 in Jdev905 preview.

Long for your reply.

    It's useless to implement set tag in uix2.1.7 because it needs MutableDataObject and there is no this kind objects in uix2.1.7.

    Daniel,

    As you say, implementing the generic "set" handler would not be so easy to do. When iDS 10g (which contains JDeveloper 9.0.4) comes out, it will include a later version of UIX 2.1 that does have the set handler (and thus MutableDataObject).

    For <compound>, one workaround is to use <bc4j:chaining>. It requires you to load the BC4J UIExtension, but it functions just like compound.

    Other than these things, you'll have to just use method/instance handlers (unless you want to go to the more substantial effort to make your own tags via a UIExtension). As you can see, we have done a lot of work on trying to make these things more usable in later releases.
