This Belated Week in Wonder

Yeah. It's been a few weeks. I know .... Better late than never:

Ajax
AjaxExpansion - If you've ever tried to make a component that has a triangle (or whatever) that you can turn down to show additional information, you know it's actually a little tricky to build that component and make it animate nicely with a slide down effect. AjaxExpansion makes this easy to do and there is an addition to the AjaxExample2 ToggleDetails example that shows how to use it.

By popular demand, AjaxTabbedPanel can now hide tabs.

AjaxUpdateLink, AjaxSubmitButton, and AjaxObserveField now support updateContainerID="_parent", which will update the nearest ancestor component AjaxUpdateContainer. This makes it so you don't have to pass id's around in the common case that you're just updating your parent container.

There's a new example of using AjaxModalContainer in AjaxExample2.

Chuck fixed tons of weird little border cases.

AjaxModalDialog is now in ... It's a competitor to AjaxModalContainer based on the modalbox Javascript library, but is designed to have a slightly nicer component backend that can track the open state on the server side (which allows for fancier component content). There's a new AjaxExample that shows this in action.

ERExtensions
ERXExceptionUtilities provides a bunch of handle methods for printing and handling stack traces, including stack trace filtering that tries to hide all those nasty looking WO/EOF stack frames. See the javadoc for more info. Also, you can set your log appender to er.extensions.logging.ERXConsoleAppender to get stack trace filtering wired into all of your log4j output. Check out StackTraceSkipPatterns-Normal.plist in ERExtensions/Resources to see how you can provide your own stack trace filtering extensions.

ERXApplication can now load Properties from inside of jar frameworks.

multipleSubmit=true is now defaulted on for all WOForms. Rest in peace stupid binding.

ERXLazyValue provides a way to model lazy-loaded values that invalidate with different methods. This is very useful for storing expensive values that are returned from bound component methods as well as values that are cached that are influenced by different areas of a single page (i.e. ajax operations on one part of the page that need to invalidate a cache on another part of the page).

ERXDisplayGroup now uses generics.

ERXKey now uses generics in all of the .is(..) etc methods.

ERXWOComponentContent is now a little bit slicker and supports the concept of a "default" template. If you define an ERXWOComponentContent with no template name, it will find all of the component content children that are not contained inside of an ERXWOTemplate and treat them as if they were in a default component content.

There's an NSBundle replacement in Wonder now. This fixes a bug with jar loading in embedded frameworks that would end up loading in the application bundle, which causes the very common bug of getting a Session class that isn't your Session. This is also provides some support for making launching non-WOApplication WO things (like EOF main methods) in WOLips a little smarter.

ERXFetchSpecification has a new setIncludeEditingContextChanges(boolean) option. When true, fetching with this fetch spec will call through ERXEOControlUtilities.objectsWithQualifier and also process the new (uncommitted) changes from your EC. For instance, if you have inserted EO's into your EC, includeEditingContextChanges = true will cause those new EO's to be included in the results of the fetch. Likewise, updated, deleted, and parent EC objects will be processed accordingly.

ERPrototypes
New IP Address prototype (along with new migration methods to support it).

New byte24 prototype for generating guid PKs.

Maven
Both the 5.3 and 5.4 version of Wonder can be now be built with Maven. Talk to Henrique for more info :)

ERAttachment
You can now register a custom delegate onto your ERAttachmentProcessors to be notified of various events in the attachment lifecycle. This allows your application to perform additional operations in response to those events.
