Chapter 16. Seam JSF controls

Seam includes a number of JSF controls that are useful for working with Seam. These are intended to complement the built-in JSF controls, and controls from other third-party libraries. We recommend the Ajax4JSF and ADF faces (now Trinidad) tag libraries for use with Seam. We do not recommend the use of the Tomahawk tag library.

<s:validate>

Validate a JSF input field against the bound property using Hibernate Validator.

<s:validateAll>

Validate all child JSF input fields against the bound propertys using Hibernate Validator.

<s:convertDateTime>

Perform date or time conversions in the Seam timezone.

<s:decorate>

"Decorate" a JSF input field when validation fails.

<s:message>

"Decorate" a JSF input field with the validation error message.

<s:span>

Render a HTML <span>.

<s:div>

Render a HTML <div>.

<s:cache>

Cache the rendered page fragment using JBoss Cache. Note that <s:cache> actually uses the instance of JBoss Cache managed by the built-in pojoCache component.

key — the key to cache rendered content, often a value expression. For example, if we were caching a page fragment that displays a document, we might use key="Document-#{document.id}".
enabled — a value expression that determines if the cache should be used.
region — a JBoss Cache node to use (different nodes can have different expiry policies).

<s:link>

A link or button that supports invocation of an action with control over conversation propagation.

value — the label.
action — a method binding that specified the action listener.
view — the JSF view id to link to.
fragment — the fragment identifier to link to.
linkStyle — either link, the default, or button.
buttonClass — the css class for the button.
propagation — determines the conversation propagation style: begin, join, nest, none or end.
pageflow — a pageflow definition to begin. (This is only useful when propagation="begin" or propagation="join".)

<s:conversationPropagation>

Customize the conversation propagation for a command link or button (or similar JSF control). Facelets only.

propagation — determines the conversation propagation style: begin, join, nest, none or end.
pageflow — a pageflow definition to begin. (This is only useful when propagation="begin" or propagation="join".)

<s:conversationId>

Add the conversation id to an output link (or similar JSF control). Facelets only.

<s:taskId>

Add the task id to an output link (or similar JSF control), when the task is available via #{task}. Facelets only.

<s:action>

Attach an action listener to an output link (or similar JSF control). Facelets only.

action — a method binding that specified the action listener.

<s:selection>

Propagate the selected row of a DataModel with an output link (or similar JSF control). Facelets only.
