Tag name: <tr:spacer>
UIComponent class: org.apache.myfaces.trinidad.component.core.output.CoreSpacer
Component type: org.apache.myfaces.trinidad.CoreSpacer
spacer occupies a fixed amount of space in a layout, specified by its width and height attributes. If the width is not specified, but height specified, a block level HTML element is rendered, thereby introducing a new line effect. If width is specified, then, irrespective of the specified value of height, it may not get shorter than the applicable line-height, in user agents that strictly support standards mode HTML.

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.|
|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||org.apache.myfaces.trinidad.component.core.output.CoreSpacer||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.|
|height||String||Yes||the height of the spacer item.|
the identifier for the component. Every component may be named by a component identifier that must conform to the following rules:
|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.|
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.
|shortDesc||String||Yes||the short description of the bean. This text is commonly used by user agents to display tooltip help text.|
|width||String||Yes||the width of the spacer item.|
