19 19  * Automatic EOEditingContext locking. This feature is huge. We'll talk about locking a lot in later sections, but trust me, you'll want WONDER to handle the locking for you. No more unlocked contexts to be corrupted while you edit them, and no more deadlocks and locked contexts lying around.

21 -* Collections re-implementation supporting Java Generics. This means that you may create an NSArray, NSDictionary or any other "NS collection" typed to a class or interface. I don't actually like this feature, because I'm a LISP lover and I see this as unnecessary constraints. Anyway, I mention this because I admit it may improve the code quality in some ways, and because WONDER implementation is, in some ways, better than Apple's (Apple delivered generics support for collections in 5.4).
21 +* collections with attachements

23 -* COUNT SQL query generation. This is a very, very useful feature, at least for me. There are many times when you just want to know how many objects are selected by a query, but you don't want the objects themselves, specially because we may be talking about tens of thousands, or more. Think something like Amazon querying its system for the number of books sold this month. The query results would be huge and unpractical to manage in memory and time, and an unacceptable overhead if all you want is the count. WONDER provides a very easy way to do COUNT (and COUNT UNIQUE) queries.
23 +* count and count unique

25 -* Extra qualifiers. Sometimes WO qualifiers are simply not enough. WONDER provides some handy qualifiers. Some of them are buggy and may not work, it's not one of the best quality WONDER features, but at least it's there, and it's open source, so you can fix any bugs you find.
25 +* qualifiers

27 -There are many, many more nice things about EXExtentions framework. You would be really bored if I described only 10% of them. Besides ERExtentions, there are also a number of cool extra frameworks in WONDER. Here are some of them:

29 -* Ajax Framework - provides a really easy way to add Ajax calls to your application. Ajax Framework integrates Ajax in the WebObjects Request-Response loop in a very intelligent way. You program all of the Ajax stuff as you program normal component actions. An action method is called, you do whatever you want, and return a component (usually null). The defined block of the page is updated. No page reload, the user is happy, and you are more than happy because you actually had to do nothing (well, almost). We'll look at Ajax Framework later.
29 +* Ajax

33 -* ERPrototypes - A collection of data model prototypes for popular databases. You may use this framework or create your own prototypes, but **do** use prototypes. If you are lost, don't worry, we'll look at this later.
33 +* Prototypes

35 -* ExcelGenerator - A POI wrapper framework for generating Excel documents, a very useful feature in many web applications.
