Helo Dave:

Yes and no. What I´m meant is that I could move them but without using the rule machine. This is how:

- 1st: All my D2JC screens using the Assistant (in WO 5.3) I freezed them in a XML file. The ones that already have been freezed, no modification was done.
- 2d: I develop a class called MyControllerFactory that work similar as the EOControllerFactory class but without calling the rule machine. This is how it works:
+ This class (in the client side) calls the server to get the XML file of the WOComponent that I want to show.
+ With the XML file, the MyControllerFactory class parse it and instantiated the D2J classes (EOFormController, EOListController, EOTextFieldController, etc.) programatically (see the JCEntityViewer example if you need more detail).
- 3rd: Show the root controller as a Window or Modal screen.

So far it worked ok, but I have not tested with all D2J classes.

note: I have to develop some minor additions:

(a) Need to subclass the EOFormController and EOListController to catch the defaultActions() method in order NOT to go to the ruler machine and return the NSArray of EOActions statically.
(b) With these two subclasses I have to override some methods (i.e., OpenWithTask, InsertWithTask and insert) in order to do the actual operation without the rule machine.

Result: All the D2J screens keep the same. What I throw away was the rule machine (too complicate and time consuming for me to simulate its operation). The migration for existing D2J system was not so hard since we did not use the rule machine very much.

The rule machine some how gave you the screen flow between D2J screens; this flow you have to re-code and you could do it in many ways (i.e., in the client (e.g, I add extra tag in the EOFormController called 'nextTask') or in the server).

I hope these ideas could help you.

Ricardo.

Hey Ricardo,

I'd like to move to WO 5.4, but my core application is D2JC right now. I'm planning on moving it straight JC using Flor's JBND framework in the near future, but I'm stuck with it for now.

Can you get D2JC apps to work with 5.4 by bringing over the 5.3 D2JC classes? If so, how?

Thanks,

Dave

More to JC in my case for simple screen I´m still using the D2JC controllers classes programatically with WO 5.4.1
