"Tomahawk JSF 是一个扩展了标准JavaServer Faces (JSF)库的开源项目，由Apache MyFaces社区开发。这个参考文档详细介绍了Tomahawk标签库的使用，版本为1.2，与JSF 1.1.7兼容。Tomahawk库提供了一系列额外的组件和功能，旨在增强JSF的应用开发体验。" 在JSF环境中，Tomahawk标签库通过URI"http://myfaces.apache.org/tomahawk"被引用，它包含了一系列用于各种用途的自定义标签。这些标签可以极大地提高开发效率，并提供标准JSF组件未涵盖的功能。 1. **aliasBean**：aliasBean标签允许开发者创建一个临时名称来引用一个实际的bean。这对于在不同上下文中引用同一个bean或者在避免名称冲突时特别有用。 2. **aliasBeansScope**：这是一个范围，可以存储多个由aliasBean标签配置的别名。这提供了一种管理多个别名的方式，使得在不同部分的代码中可以使用不同的名称访问相同的bean。 3. **buffer**：buffer组件将它的子组件渲染到内存缓冲区，而不是直接写入响应流。这在需要对输出进行操作或者在某些情况下需要延迟渲染时非常有用。 4. **captcha**：Tomahawk提供了验证码支持，这是一个防止自动机器人或恶意用户操作的常用安全机制。它可以生成和验证用户输入的一组随机字符，确保操作是由人类执行的。 5. **checkbox**：checkbox标签渲染出HTML中的`<input type="checkbox">`元素，用于在表单中创建可选的复选框。 6. **collapsiblePanel**：这个组件可以折叠成一个图标（可选带标签），当点击后会展开显示其内容。它在创建可折叠的界面元素，如面板或菜单时非常有用，有助于提高用户体验和界面的整洁性。 7. 除了上述标签，Tomahawk库还包含了许多其他标签，例如用于表格操作、表单处理、文件上传、日期选择等的组件。这些组件丰富了JSF开发者可用的工具箱，使得构建更复杂、交互性更强的Web应用程序成为可能。 Tomahawk JSF参考PDF是开发者学习和利用这些自定义标签的宝贵资源，通过深入理解并应用这些标签，开发者可以更好地利用JSF框架，提升应用的性能和用户体验。

return value, called the action outcome, that identifies the next view displayed. The

can be controlled via the immediate attribute. If the value is a string literal,

outcome for the current view. This is functionally equivalent to a reference to an action

string literal.

actionFor Comma separated list of subForm-ids for which validation and model update should

is executed. You need to wrap your input components in org.apache.myfaces.custom.subform.SubForm

for this to work.

actionListener

active Menu node is active.

activeOnViewIds A comma separated list of viewIds for which this item should be active.

binding Identifies a backing bean property (of type UIComponent or appropriate subclass)

instance. This value must be an EL expression.

charset HTML: Specifies the character encoding of the linked resource.

coords HTML: The coordinates of regions within a client side image map.

dir HTML: The direction of text display, either 'ltr' (left-to-right) or 'rtl' (right-to-left).

disabled When set instead of a Hyperlink a span tag is rendered in the corresponding Component

disabledStyle CSS-Style Attribute to render when disabled is true

disabledStyleClass CSS-Style Class to use when disabled is true

enabledOnUserRole If user is in given role, this component will be rendered normally. If not, no hyperlink

(=body) are rendered.

externalLink The external link where to redirect when this is clicked.

forceId If true, this component will force the use of the specified id when rendering.

forceIdIndex If false, this component will not append a '[n]' suffix (where 'n' is the row index) to

within a "list." This value will be true by default and the value will be ignored if the

specified.)

hreflang HTML: The language of the linked resource.

id Get a string which uniquely identifies this UIComponent within the scope of the nearest

component. The id is not necessarily unique across all components in the current

lang HTML: The base language of this document.

onblur HTML: Specifies a script to be invoked when the element loses focus.

onclick HTML: Script to be invoked when the element is clicked.

ondblclick HTML: Script to be invoked when the element is double-clicked.

onfocus HTML: Specifies a script to be invoked when the element receives focus.

onkeydown HTML: Script to be invoked when a key is pressed down over this element.

onkeypress HTML: Script to be invoked when a key is pressed over this element.

onkeyup HTML: Script to be invoked when a key is released over this element.

onmousedown HTML: Script to be invoked when the pointing device is pressed over this element.

onmousemove HTML: Script to be invoked when the pointing device is moved while it is in this element.

onmouseout HTML: Script to be invoked when the pointing device is moves out of this element.

onmouseover HTML: Script to be invoked when the pointing device is moved into this element.

onmouseup HTML: Script to be invoked when the pointing device is released over this element.

open Menu node is open.

rel HTML: The relationship between the current document and the linked resource.

rendered A boolean value that indicates whether this component should be rendered. Default

rev HTML: The type(s) describing the reverse link for the linked resource.

shape HTML: The shape of a region in a client side image map.

style HTML: CSS styling instructions.

styleClass The CSS class for this element. Corresponds to the HTML 'class' attribute.

tabindex HTML: Specifies the position of this element within the tab order of the document.

target HTML: Names the frame that should display content generated by invoking this action.

title HTML: An advisory title for this element. Often used by the user agent as a tooltip.

type HTML: A hint to the user agent about the content type of the linked resource.

value The text to display to the user for this command component.

visibleOnUserRole If user is in given role, this component will be rendered normally. If not, nothing is

tag will be skipped.

<t:commandSortHeader>

Clickable sort column header. Must be nested inside an extended data_table tag. This tag

is derived from the standard command_link tag and has the additional attributes

columnName and arrow. Note: In contrast to normal command links, the default for the

"immediate" attribute is "true". This is desirable as it avoids validating all input fields in the

enclosing form when the column sort order changes. HOWEVER when the table contains

input components "immediate" must be set to false; otherwise input fields will render

blank after a sort, or will show their old values (ie will not appear to sort though output

fields in the table will sort) when sort ordering is changed. Unless otherwise specified, all

attributes accept static values or EL expressions.

action The action to take when this command is invoked. If the value is an expression,

string literal.
