af:carousel carousel carousel

UIComponent class: oracle.adf.view.rich.component.rich.data.RichCarousel
Component type: oracle.adf.RichCarousel

Naming container: Yes. When referring to children of this component ("partialTriggers", findComponent(), etc.), you must prefix the child's ID with this component's ID and a colon (':')

The carousel component displays a spinning series of items based on rows of a collection model.

Carousel Model

The carousel component uses a model to access the data in the underlying list. The specific model class is oracle.adf.view.rich.model.CollectionModel. You may also use other model instances, e.g., java.util.List, array, and javax.faces.model.DataModel. The carousel will automatically convert the instance into a CollectionModel.

Fetch Size

The carousel component is virtualized. This means that not all the rows that are available for the component on the server are fetched and displayed on the client. The number of rows that are displayed on the client should generally be just enough to fill the viewport. More rows are fetched as the user spins the carousel. "fetchSize" is the number of rows requested from the client to the server on each attempt to fill the component. So if the space allocated for the carousel is small, the fetch size of 25 may be sufficient to fill the component. However if the space allocated for the carousel is large, there might be a need to request the data multiple times from the server. If the carousel has to make a request to the server 2 times when fetchSize is 25, it may be appropriate to set the fetchSize to 50.

CSS Style Restriction

The carousel requires dimensions to display. Either the carousel must be placed in a parent component that will stretch it or the carousel must have explicit dimensions which are provided by the skin. You need to be careful to not apply an inlineStyle or styleClass that would change the dimensions to be indeterminate.

Geometry Management

Attribute Notes

The "first" and "rows" attributes inherited from the UIXIterator superclass are not currently supported for the rich render kit.

Events

Type Phases Description
oracle.adf.view.rich.event.CarouselSpinEvent Apply Request Values,
Invoke Application
The spin event is delivered when the table selection changes.
org.apache.myfaces.trinidad.event.AttributeChangeEvent Invoke Application,
Apply Request Values
Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change event might include the width of a column that supported client-side resizing.

Supported Facets

Name Description
nodeStamp the component to use to stamp each element in the carousel. A carouselItem child is required. As with JSP pages, when using Facelets, multiple components are not allowed in this facet.

Attributes

Name Type Supports EL? Description
attributeChangeListener javax.el.MethodExpression Only EL a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.
binding oracle.adf.view.rich.component.rich.data.RichCarousel Only EL an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.
carouselSpinListener javax.el.MethodExpression Only EL a method reference to a carousel spin listener
clientComponent boolean Yes Default Value: false

whether a client-side component will be generated. A component may be generated whether or not this flag is set, but if client Javascript requires the component object, this must be set to true to guarantee the component's presence. Client component objects that are generated today by default may not be present in the future; setting this flag is the only way to guarantee a component's presence, and clients cannot rely on implicit behavior. However, there is a performance cost to setting this flag, so clients should avoid turning on client components unless absolutely necessary.
contentDelivery String Yes Valid Values: immediate, lazy
Default Value: lazy

whether data should be fetched when the component is rendered initially. When contentDelivery is "immediate", data is fetched and inlined into the component chrome. If contentDelivery is "lazy", data will be fetched and delivered to the client during a subsequent request.
controlArea String Yes Valid Values: full, small, compact
Default Value: full

specifies how the area where the user spins the carousel is presented. The "full" option lets a user spin through carousel items one at a time, jump to a specific item, or drag the slider thumb to continuously spin the carousel until the mouse is let go. The "small" option lets a user click the next and previous buttons to spin through carousel items one at a time. The "compact" option is similar to "small" but omits details such as the "x of y" progress information.
currentItemKey Object Yes the key that identifies the current item in this component.
customizationId String Yes This attribute is deprecated. The 'id' attribute should be used when applying persistent customizations. This attribute will be removed in the next release.
disabled boolean Yes Default Value: false

a boolean which if the value is "true", the component becomes non-interactive. Otherwise, the default value is "false" and component assumes its expected behavior.
displayItems String Yes Valid Values: circular, oneByOne
Default Value: circular

the current carousel item will always be shown but you can use this attribute to specify how the auxiliary carousel items are displayed. Use "circular" if you want the auxiliary items displayed near the current item in a scaled down pattern with as many items shown as will fit. Use "oneByOne" if you only want the current item shown.
emptyText String Yes the text of an empty carousel. If the text is enclosed in an open and closing html tag, it will be formatted. The formatting behavior is similar to outputFormatted component. If it is not enclosed in an open and closing html tag, it will not be formatted.
fetchSize int Yes Default Value: 25

the number of rows in the data fetch block
Not supported on the following renderkits: org.apache.myfaces.trinidad.core
first int Yes Default Value: 0

the first property is used internally in the rich client and should not be set externally
Not supported on the following renderkits: oracle.adf.rich
halign String Yes Valid Values: start, center, end
Default Value: center

determines the horizontal alignment of the carousel items.
id String No the identifier for the component. The identifier must follow a subset of the syntax allowed in HTML:
  • Must not be a zero-length String.
  • First character must be an ASCII letter (A-Za-z) or an underscore ('_').
  • Subsequent characters must be an ASCII letter or digit (A-Za-z0-9), an underscore ('_'), or a dash ('-').
immediate boolean Yes Default Value: false

whether or not data validation - client-side or server-side - should take place when events are generated by this component. When immediate is true, the default ActionListener provided by the JavaServer Faces implementation should be executed during Apply Request Values phase of the request processing lifecycle, rather than waiting until the Invoke Application phase.
inlineStyle String Yes the CSS styles to use for this component. This is intended for basic style changes. The inlineStyle is a set of CSS styles that are applied to the root DOM element of the component. Be aware that because of browser CSS precedence rules, CSS rendered on a DOM element takes precedence over external stylesheets like the skin file. Therefore skins will not be able to override what you set on this attribute. If the inlineStyle's CSS properties do not affect the DOM element you want affected, then you will have to create a skin and use the skinning keys which are meant to target particular DOM elements, like ::label or ::icon-style.
orientation String Yes Valid Values: horizontal, vertical
Default Value: horizontal

horizontal (the default) for the images being displayed along an x-axis or vertical for y-axis.
partialTriggers String[] Yes the IDs of the components that should trigger a partial update. This component will listen on the trigger components. If one of the trigger components receives an event that will cause it to update in some way, this component will request to be updated too. Identifiers are relative to the source component (this component), and must account for NamingContainers. If your component is already inside of a naming container, you can use a single colon to start the search from the root of the page, or multiple colons to move up through the NamingContainers - "::" will pop out of the component's naming container (or itself if the component is a naming container) and begin the search from there, ":::" will pop out of two naming containers (including itself if the component is a naming container) and begin the search from there, etc.
rendered boolean Yes Default Value: true

whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.
rows int Yes Default Value: 25

the rows property is used internally in the rich client and should not be set externally
Not supported on the following renderkits: oracle.adf.rich
shortDesc String Yes the short description of the component. This text is commonly used by user agents to display tooltip help text, in which case the behavior for the tooltip is controlled by the user agent, e.g. Firefox 2 truncates long tooltips. For form components, the shortDesc is displayed in a note window. For components that support the helpTopicId attribute it is recommended that helpTopicId is used as it is more flexible and is more accessibility-compliant.
styleClass String Yes a CSS style class to use for this component. The style class can be defined in your jspx page or in a skinning CSS file, for example, or you can use one of our public style classes, like 'AFInstructionText'.
unsecure java.util.Set Yes A whitespace separated list of attributes whose values ordinarily can be set only on the server, but need to be settable on the client. Currently, this is supported only for the "disabled" attribute. Note that when you are able to set a property on the client, you will be allowed to by using the the .setProperty('attribute', newValue) method, but not the .setXXXAttribute(newValue) method. For example, if you have unsecure="disabled", then on the client you can use the method .setProperty('disabled', false), while the method .setDisabled(false) will not work and will provide a javascript error that setDisabled is not a function.
valign String Yes Valid Values: middle, top, bottom
Default Value: middle

determines the vertical alignment of the carousel items.
value Object Yes the data model being used by this component. The specific model class is org.apache.myfaces.trinidad.model.CollectionModel. You may also use other model instances, e.g., java.util.List , array, and javax.faces.model.DataModel. This component will automatically convert the instance into a CollectionModel.
var String No Name of the EL variable used to reference each element of this collection. Once this component has completed rendering, this variable is removed (or reverted back to its previous value).
varStatus String No Name of the EL variable used to reference the varStatus information. Once this component has completed rendering, this variable is removed (or reverted back to its previous value). The VarStatus provides contextual information about the state of the component to EL expressions. For components that iterate, varStatus also provides loop counter information. Please see the this component's documentation for the specific properties on the varStatus. The common properties on varStatus include:
  • "model" - returns the CollectionModel for this component
  • "index" - returns the zero based row index
visible boolean Yes Default Value: true

the visibility of the component. If it is "false", the component will be hidden on the client. Unlike "rendered", this does not affect the lifecycle on the server - the component may have its bindings executed, etc. - and the visibility of the component can be toggled on and off on the client, or toggled with PPR. When "rendered" is false, the component will not in any way be rendered, and cannot be made visible on the client. In most cases, use the "rendered" property instead of the "visible" property.
Not supported on the following renderkits: org.apache.myfaces.trinidad.core
