Re: ERXEOControlUtilities usage and Scala
I am far from a Scala or functional programming expert, so I wouldn’t take anything here as definitive. John Huss pointed me toward Scala templates for EOGenerator (http://wiki.wocommunity.org/plugins/servlet/mobile#content/view/2622529) and I have been working on some isolated projects with those because I don’t yet have the time to refactor everything in my EO Frameworks with the new templates. These templates look like they’ll make dealing directly with EO’s simpler from Scala but I have some questions about how the EOFramework would be used from Java (because we still have apps that use the frameworks in Java). I am probably just being paranoid, because it looks like it should be a drop in replacement, but I will have to refactor the entity custom logic to scala. I look forward to cleaning up that code, but it’s not going to be a small job. When I have a bit more testing of the Scala EOs and how they work and play well with existing java, I’ll start migrating them. I started integrating Scala with EOF for command line tools and bulk analysis and found that using scala.collection.JavaConversions._ allowed me to use toList to treat the NSArrayT resulting from an ERXEOControlUtilities.objectsWithQualifier call using the common recursion and mapping of Scala collections. I do require some casting (asInstanceOf[]) occasionally, but I look at those places as examples of what I don’t yet know about how to work with Scala because most of the time I can find a better way to do this. I think the scala EO templates will help a lot in this regard. There is a lot of Scala that I have trouble interpreting but even with a rudimentary understanding of the language and FP, I am finding the code coming out is more concise and testable. Some of that is paying more explicit attention to side-effects and mutability (which I should have been doing more of in Java anyway), but re-writing some of the aggregation/analysis tools that already used recursive patterns has resulted less code and lower memory usage in most cases.

I’m using scala with WebObjects/Wonder for a number of apps including a bunch of data loading/analyzation utilities (also exposed as services) This works extremely well and seamlessly (thanks to some of the scala.collection.JavaConversions._ and other bits), but there are a couple things about using EO’s that I’m working around and I wonder if someone here has more insight into where this mismatch is happening. Using ERXEOControlUtilities.createAndInsertObject(…) results in errors that the EOClassDescription cannot be found. Calling: val lab = ERXEOControlUtilities.createAndInsertObject(emrec, BloodMeasurement).asInstanceOf[BloodMeasurement] ...will fail ( but val lab = new BloodMeasurement() emrec.insertObject(lab) … works normally (but feels so 1998) It looks like scala is not getting the class descriptions from the model, but I wouldn’t expect it to care if ERXEOControlUtilities is the class that needs the model. As long as I’m asking Scala questions, is there a way to use the static fields of the eogenerated classes without addressing them directly? (Perhaps this is an Eclipse issue, but the compiler doesn’t seem to know about BloodMeasurement.ENTITY_NAME, but it does know about _BloodMeasurement.ENTITY_NAME. I imagine this has something to do with how Scala treats “companion objects” in relation to static fields in Java, but I don’t know if there is a way to deal with this more elegantly (as there is with all of the collections and functional goodness in Scala) Larry Mills-Gahl elem...@gmail.com ___ Do not post admin requests to the list.

Re: D2W Enum Query
You might consider a rule that covers all cases.

Re: Eclipse 4.4 support for WOLips
Currently, it's DIY (or better: build it yourself, from repository mentioned in first mail). Pascal Robert, do you need any help with adding it to jenkins and building official version ?
