Re: Migrating from EOF to Cayenne
Hi; I can't speak for WO integration but from the perspective of using Cayenne with other infrastructure, I can say that I enjoyed working with Cayenne a while back -- I'm sadly not using it at the moment. Coming from an integrated stack like WO, it is possible to forget that Cayenne is focused on the object-relational bit; be careful to evaluate it in terms of its remit. cheers. I agree that we need to more closely examine Cayenne before jumping in with both feet. -- Andrew Lindesay ___ Do not post admin requests to the list. They will be ignored.

Re: Migrating from EOF to Cayenne
Cayenne is still missing a lot of functionality when compared to EOF/Wonder and generally feels less mature (understandably, since EOF is ancient). This is perhaps not such a huge problem, since functionality can always be added—but there is indeed a *lot* of work to be done to reach feature parity with EOF. That seems like an overstatement to me. What things is it missing that you need? Well, it isn't exactly big things that are missing, but rather an aggregation of a lot of small things. Things I can live without, but would rather not. EOF, Foundation, Wonder and the tools have 20 years of refinement and integration in their design so moving from EOF to Cayenne feels a little like moving from a Mercedes to a Wolkswagen Bug. Lack of IDE support, no prototypes, no KVC, getAccessor (ugh), limited support for inheritance, no ERXKey means no type safe queries and strings everywhere, somewhat buggy modeler with no support for cross-model relationships, no crossing relationships in raw row fetches (which makes it harder to create reports from huge object graphs), no Project Wonder EO stuff etc. etc. Now, I know this comparison is unfair to Cayenne which is in fact great, and Andrus and the others have done an amazing job. EOF is just hard to beat, because EOF is very, very good. And as I said, Cayenne will no doubt get there, I just believe it will take a lot of work. The only reasonable way to do a re-implementation of EOF would be to start with Cayenne. It doesnt have the same API as EOF, but that could be done; that hard work has already been done, only the API would need change. But I think there are advantages in trying to merge with the Cayenne community rather than taking it and forking it. I agree. If they're compatible it's probably the way to go. - hugi ___ Do not post admin requests to the list. They will be ignored.

Re: Migrating from EOF to Cayenne
I apologize if this has already been suggested or discussed elsewhere, but it might be a worthwhile exercise to extend the API and feature comparison on the WIKI (http://wiki.wocommunity.org/display/WO/Alternative+Technologies-Cayenne ... thanks John) in the direction of a roadmap between where we are right now with EOF and Cayenne and what a Cayenne that includes the best of EOF/Wonder. I know this is not a trivial task, but if we either extended the existing WIKI section or created this as an explicit roadmap, it could help focus the discussion and resources so that we'll at least have a reasonable understanding (as a community) of what we need to do to get to this integration (and more fundamentally, if we want to do this). Another benefit from the perspective of the cayenne community would be to be able to see what features we are looking for and willing to work on so that it's clear we are not competing with their roadmap, but perhaps adding extra lanes on the road. It might also help in looking for financial support for elements of the evolution of cayenne/eof. I think some version of the feature comparison table and the API comparison table might suit to start this process. If we look at those tables with an eye toward how much effort it would take to implement we could begin to prioritize areas and seek support for projects that are less straight-forward and require some heavy lifting. Paul Yu had (what I think is) a very good idea in defining tests for the functionality that we need. I'm certainly not suggesting this is a trivial task, but I think defining what success would look like will help us recognize when we get there. (Paul, sorry if I've misinterpreted your idea ... but it was hot and the sun was in my eyes on the forced march back over the bridge) Any thoughts?

Re: Escaping property files keys
Hi Benjamin,
The value defined by the er.attachment.s3.key property is always encoded. It
doesn't cause any real problem in runtime besides the ugly URL. One possible
solution is to convert '%2F' back to '/' after the URL encoding executed here
[1].

Hello All,
I was having an issue with ERAttachment (s3 mode). When setting the property
file attribute:
er.attachment.s3.key=projectName/${pk}${ext}
The '/' gets escaped into '%2F'. The default value is ${pk}${ext} (primary
key).(mime extension) which work as expected.
I've tried several options such as escaping with a backslash, feeding it the
%2F instead, or any other tweaks I could think of, but it always comes out as
URL encoding.
Any thoughts on this? I would like to avoid programmatically setting this,
as the ERXAttachmentUploader and such classes are concise and handy.
Thanks!

Cayenne is still missing a lot of functionality when compared to EOF/Wonder and generally feels less mature (understandably, since EOF is ancient). This is perhaps not such a huge problem, since functionality can always be added—but there is indeed a *lot* of work to be done to reach feature parity with EOF. It's clear that at some point most of us will have to stop using EOF in it's current form. In a perfect world (that's the world where I have endless time and money) I'd do a clean room implementation of EOF and live happily ever after. But this is indeed not a perfect world, so helping making Cayenne better and more integrated with WO seems like a more realistic goal (besides, it allows more resources to be spent on a re-implementation of WO; something I'd love to participate in).

Re: Migrating from EOF to Cayenne
Hi John Hugi; True, this is the biggest gap I've come across - I have an app that does exactly that. However, there are a few built-in alternatives, namely SQLTemplate and EJBQLQuery. But if you have a lot of this in your app, you'll probably want to wait to consider migrating. In my use of Cayenne I have created a set of objects like f.s. and friends that render to JPQL and in doing this I can't immediately think of any 'blockers'. cheers. -- Andrew Lindesay ___ Do not post admin requests to the list.

Re: Problem EOEditingContext
Hola Hugo,
Bienvenido!
If you are using the EOGenerate templates for your EO classes you'll also find
this code is generated for you. For example in my _Person.java class:
public static com.wowodc.model.Person createPerson(EOEditingContext
editingContext) {
com.wowodc.model.Person eo = (com.wowodc.model.Person)
EOUtilities.createAndInsertInstance(editingContext, _Person.ENTITY_NAME);
return eo;
}
Your method to create a user then becomes User.createUser(ec);
Saludos,
David

object to the EOEditingContext
one of the WO commandments:
always insert your EO immediately after creating it. i.e. after new User()
and before setting any attributes.
alternatively you can use
User newUser = (User)EOUtilities.createAndInsertInstance(ec,
User.ENTITY_NAME) ;
ec.saveChanges();//Commit
to the DataBase
But, the server has the next error:
java.lang.RuntimeException: You crossed editing context boundaries
attempting to set the 'role' relationship of your.app.model.User pk:null
(which is not in an editing context) to your.app.model.Role pk:2 (in EC
er.extensions.eof.ERXEC@762a5241).
I understand that the primary key of the user is null, because it's a new
user and I want to insert it to the data base.
What is the correct way to insert row, when it have a relationship between
the entities?
Thanks for you time

Re: Problem EOEditingContext
Thanks for your answers, yes I found a method like this: public static User createUser(EOEditingContext editingContext, String maternalName , String name , String password , String paternalName , String username) But I prefer to user the method like this: User newUser = ERXEOControlUtilities.createAndInsertObject(ec, User.class ); On Thu, Jul 12, 2012 at 5:39 PM, Lon Varscsak lon.varsc...@gmail.comwrote: Oh, I like that! -Lon On Thu, Jul 12, 2012 at 3:26 PM, Maik Musall m...@selbstdenker.ag wrote: Am 12.07.2012 um 23:58 schrieb Louis Demers: User newUser = (User)EOUtilities.createAndInsertInstance(ec, User.ENTITY_NAME) ; Much too wordy for my taste, and needs a cast on top of it.
