Multiple parent-shuttle pages

Question

Hi guys,
I'm using Jdeveloper 10.1.2 and JHeadstart 10.1.2 (build 19).
I've developed a page that contains a master view object and two detail view objects. What I want to do is to display both as parent shuttles on the same page. I have created 2 detail parent-shuttle groups and set both to display on same page. The two shuttle groups are displayed fine but the problem is when it comes time to saving the changes on the page. It seems that only the first shuttle group is being updated and the second one ignored. I checked that I wasn't doing anything silly but setting the second parent-shuttle to display on a separate page and when it was, the update of both work fine.
Is it not possible to have two parent shuttle's on the same page ?
Cheers,
Brent

Brent,
It turns out that, while not documented, this is not supported. The method name generated into the UI Model to process the shuttle has the id "processParentShuttle". So, if you have two shuttles, the second shuttle overrides the first shuttle method binding .....
You could fix that manually, by adding a second shuttle method binding to the UI Model with a different name, but when you do that, you also need to subclass JhsDataAction, and override method processShuttle which currently only checks for a parent shuttle binding named "processParentShuttle".
