[Rife-users] Sharing my experiments
Hi Geert, Well, thanks again for the quick response. I overlooked that I handled the embedded elements differently in both embedding elements. Your explanation helped me a lot in understanding how embedded elements are handled. Your suggested solution is exactly with what I started with but ended up in the background because of the 'problem' I encountered.

Re: [Rife-users] Sharing my experiments
Hi Adriaan, the reason for this is that you first handle the "reservationList" submission with the "Seats" action in the BrowseReservations element. This renders a dynamic list of embedded SeatEntry elements. When the "seatEntry" submission is however sent, the embedding element (which is BrowseReservations), didn't receive the "reservationList" submission anymore. This means that its "processElement" is executed instead (ie. the element is merely rendered, it doesn't process an action). In that method, you print the template, which processes one SeatEntry embedded element without differentiator. This embedded element has a different identifier than the one that sent the "seatEntry" submission since the differentiator is missing. One way to solve this, is to create a datalink from the "BrowseReservations" element that points to itself (with input and output "showSeats", for instance). Set the output to "true" when the seats should be shown and render then accordingly in the "processElement" method. The reflective datalink indicates to RIFE that this element has state that needs to be maintained, and when the output is set, RIFE will do so automatically. Hope this helps.

I use the 'SeatEntry' embedded element in both 'BrowseReservations' and 'ManageReservation'. In 'ManageReservation' the inline editing works ok but in 'BrowseReservations' not. The 'doSeatEntry' is just not called from the 'BrowseReservations' if the 'Save' button is clicked. Can you verify this with the sources you have? That is because I added more rudimentary functionality (Customer and Payments) in the meantime. Btw, I am considering your blog invitation.

Re: [Rife-users] Sharing my experiments
Hi Adriaan, you can download the fixes version from here: http://rifers.org/downloads/rife/snapshots/rife-1.5M2-snapshot-20060530/ Well, I am glad you used my experiments sharing to look into my 'problem' and found the solution! One of the reasons to share my experiments is to challenge other users to do the same. That is great! What would be even cooler is to talk about the things you discover, the things you like, the things you think that can improve, ... by blogging about them (and making sure your blog is on javablogs.com). If you don't have a blog, you're free to blog about RIFE at http://rifers.org/blogs, just register and tell me that I have to activate you as a blogger. What I like the most about Rife is that it allows users (even novice java programmers) to build up an application in small steps with a quick turn around time (edit, run, repair, retry) using Eclipse. Very nice way of putting it, thanks :-) Take care, Geert -- Geert Bevin Uwyn "Use what you need" - http://uwyn.com RIFE Java application framework - http://rifers.org Music and words - http://gbevin.com ___ Rife-users mailing list Rife-users@uwyn.com http://lists.uwyn.com/mailman/listinfo/rife-users

Re: [Rife-users] Sharing my experiments
Hi Adriaan, thanks a lot for your sources, I tracked it down to a bug in RIFE that creeped in with RIFE 1.4 (http://rifers.org/wiki/display/RIFE/ Embedded+element+priorities) I committed the fix and you should be able to download it form this night's nightly build. Btw, if you're processing embedded elements with dynamic differentiators, it's a good idea to make them late processing (add a + sign in front of the element id in the value tag).

Re: [Rife-users] Sharing my experiments
Hi Adriaan, It's great to see more and more people interested with RIFE and by learning Java you are really diving into a huge area of high-end software engineering. I've just taken a very brief look at your code and I must say that you are on the right path. There are a few suggestions I want to give you, though: - Take a look at Java package naming conventions. You should always use a valid domain you own to prevent collisions. For example com.yourdomain.tbs instead of just tbs. - Comment more. What seems obvious today, may be a great riddle tomorrow. It's a good habit to *always* write comments, even when writing seemingly simple code. Still try to write only non-trivial comments, there are many good guides on commenting out there. - JavaDocs. You should take a look at JavaDocs. Most editors help you with writing those. If your editor does not, try Eclipse (eclipse.org). - For Java, there is an official document with Code Formatting guidelines. Find it here: http://java.sun.com/docs/codeconv/ - It's a pain to read, but once you got it it really helps, because almost everyone is following those guidelines. All of these suggestions are more concerning your code and less your logic. It would be really time consuming to dig into what you are trying to do there. So I can only recommend you read stuff about "design patterns" and "software architecture" to learn about these things. Maybe you should also get involved in an open source project where you'll be able to get some feedback from other team members. If you have a concrete problem involving RIFE, feel free to post a precise description to this list and I'm sure someone will have a look at it.

Re: [Rife-users] Sharing my experiments
Hi Adriaan, I got your example running thad to add a couple of jars) to try to reproduce your problem. However, I can't add a new reservation since the "reservationNew" submission isn't handled by the BrowseReservation element. Inherently I can't try out the reservation list logic that fails, since there are no reservation present. Maybe you could also send a zipped archive of your hsql db?
