5 This is the release notes for XWiki Platform, XWiki Enterprise and XWiki Enterprise Manager. They share the same release notes as they are released together and have the same version.
7 This is the second milestone of the XWiki 4.2 version ([[Roadmap>>Main.Roadmap]]). This release adds support for storing an email address and a list of wiki page names in XWiki objects using dedicated xclass property types. It also adds the ability to have an object property whose value is computed from the other properties. For developers this release introduces default custom displayers for easier customization of the way XWiki object properties are displayed.
9 = New and Noteworthy (since XWiki 4.2 Milestone 1) =
11 == New field types for email and list of pages ==
13 Two new types of class properties have been added:
15 * The //Email// type extends the normal //String// type, adding by default a validation regular expression that should accept only a valid email address
16 * The //Page// type extends the normal //DBList// type, and allows to select one or more documents from the current wiki
18 These two new properties are still in development, and further improvements will be implemented in the next milestone.
20 == Computed class fields ==
22 Another new type of class fields adds support for //virtual values// computed live from other class values, data from the database, data obtained from an external service, or practically any other source of data. These fields are non-editable and aren't stored in the database, since they only provide some wiki content that will be rendered each time such a property is displayed.
24 Traditionally, this kind of computation would have been written directly in the sheet used to display instances of that class, but putting it in a class field allows easier reuse of the code, since the property will be //displayed// in livetables, when indexing the document in Lucene, when displaying documents in an index page, and so on.
26 == Improvements to the Extension Repository Application ==
28 We modified the extension sheet to display the release notes for all the available versions of an extension. Check for instance the release notes for the [[Extended TODO Application>>extensions:Extension.Extended Todo Application#HReleaseNotes]]:
30 {{image reference="ER-releaseNotes.png"/}}
32 == Improvements to Extension Manager ==
34 An administrator of a subwiki can now install XAR extension (as long as it does not require a JAR extension).
36 = For Developers =
38 == Default custom displayers for Easier customization of the way object fields are displayed ==
40 While XWiki allowed to specify a custom display for a given field, it was impossible to change the way field types, such as //DateProperty// or //IntegerProperty//, are displayed in general. Now it is possible to define custom displayers at the farm or wiki level, which gives the administrators more power to change the look and feel of the wiki. For example, this allows to use HTML5 input types for dates and numbers, to use custom suggestions for //list of users// fields, or to always add a validation input for all the //password// field types.
42 To use this feature, first you need to compute a //type// name for your property type. This is obtained from the java class simple name, removing the ##Class## suffix, and lowercasing. For example, for numbers the java class used is ##com.xpn.xwiki.objects.classes.NumberClass##, with the simple name ##NumberClass##, which gives ##number## as the type name. For a database list, we get ##dblist## from ##DBListClass##.
44 Next, there are three places where a default custom displayer can be defined.
46 1. If a document whose name is the //type// capitalized and suffixed with ##Displayer## exists in the ##XWiki## space in the current wiki, then its content is used as the default custom displayer for that type of property. For example, ##localwiki:XWiki.NumberDisplayer## and ##localwiki:XWiki.DblistDisplayer##.
47 1. If a document whose name is the //type// capitalized and suffixed with ##Displayer## exists in the ##XWiki## space in the main wiki, then its content is used as the default custom displayer for that type of property. For example, ##xwiki:XWiki.NumberDisplayer## and ##xwiki:XWiki.DblistDisplayer##.
48 1. If a velocity template whose name is the //type// suffixed with ##.vm## exists in the current skin, then it is evaluated as the default custom displayer for that type of property. A skin file can be defined in many places, such as an attachment of a skin document, a file in a named skin on the filesystem, or a file in the ##templates/## directory.
50 If a specific class property provides custom display code in the XClass, then that code takes priority over an eventual default custom displayer for that property.
52 As with property custom displayers, when evaluating the display code several objects are placed in the context:
54 * ##name## is the name of the property being displayed
55 * ##prefix## is the HTML name prefix to append to an eventual input field name, and contains the XClass name, an underscore, the object number, and another underscore, for example ##XWiki.XWikiUsers_0_##
56 * ##object## is the object owning the displayed property, an instance of the public ##com.xpn.xwiki.api.Object## class
57 * ##type## is the target display type, one of ##view##, ##edit##, ##hidden## or ##search##
59 == New API to manipulate log level ==
61 Several method as been added to ##org.xwiki.logging.LoggerManager## to manipulate the log level of registered loggers.
63 {{code language="java"}}
64 /**
65 * Associate the passed logger to the passed log level.
66 *
67 * @param loggerName the logger
68 * @param level the level of the logger
69 */
70 void setLoggerLevel(String loggerName, LogLevel level);
72 /**
73 * @param loggerName the logger
74 * @return the log level associated to the logger
75 */
76 LogLevel getLoggerLevel(String loggerName);
78 /**
79 * @return all the registered loggers
80 */
81 Collection<Logger> getLoggers();
82 {{/code}}
84 == Upgrades ==

122 {{warning}}
123 Always make sure you compare your ##xwiki.cfg## and files with the newest version since some configuration parameters were added. Note that you should add so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.
124 {{/warning}}
