Referencing Components

The Component tag is used to reference the content of a component within a presentation template or element design.

<Component name=" " context="autofill" format=" " separator=" " compute=" " htmlencode=" " awareness=" " start=" " end=" " />
<Component Opens a library component tag.
name=" " Enter the name and library of the component being referenced. For example, name="library/item". To use the library specified in the URL of the current page, use name="./item".

The "name" parameter is not used if context="autofill".

context="autofill" This parameter is only used when referencing a Component tag within a Personalization element design to display the results of a Personalization rule that searches for components.
start=" "

end=" "

The start and end attributes are used to wrap the data returned by a tag within other tags, such as HTML. These attributes are not mandatory.
format=" " This parameter is optional and can only be used with some component types:

When referencing an image component:

Use format="url" to only render the URL of an image component.

Use format="tag" to render a complete image tag. The image will be displayed on the rendered page. This is used by default if no format is specified.

When referencing file resource and image components:

  • Use format="mimetype" to render the mime type of a file or image. If no valid mime type can be determined then "www/unknown" will be rendered.

  • Use format="filename" to render the name of a file or image.

  • Use format="size" to render the size of a file or image using the most appropriate unit. If the resource is smaller then 1K then the size in bytes will be rendered. If the size of the resource is less then 1MB then the size in kilobytes will be rendered. If the size is greater than or equal to 1MB then the size will be rendered in megabytes.

  • Use format="size_bytes" to render the size of a file or image in bytes. Only the numeric value is displayed.

  • Use format="size_KB" to render the size of a file or image in kilobytes. Only the numeric value is displayed.

  • Use format="size_MB" to render the size of a file or image in megabytes. Only the numeric value is displayed.

When referencing a link component:

Use format="url" to only render the full URL of a link component.

Use format="path" to only render the site path of a link component. For example, site/sitearea/content .

Use format="tag" to render a complete link tag. This is used by default if no format is specified.

When referencing number or date elements:

In this case, the format is used to specify the display format of dates and numbers. The following formats can be defined when displaying dates:

  • format="DATE_SHORT"

  • format="DATE_MEDIUM"

  • format="DATE_LONG"

  • format="DATE_FULL"

  • format="DATE_TIME_SHORT"

  • format="DATE_TIME_MEDIUM"

  • format="DATE_TIME_LONG"

  • format="DATE_TIME_FULL"

  • format="TIME_SHORT"

  • format="TIME_MEDIUM"

  • format="TIME_LONG"

  • format="TIME_FULL"

  • format="relative" (The relative date will be displayed as either "today", "yesterday" or the number of days ago.)
You can also set user-defined formats for both dates and numbers.

When referencing user details:

When formatting user details, the format parameter is used to define which LDAP parameter to use when displaying user details. For example:

  • format="cn" is used to display the common name.

  • format="dn" is used to display the distinguished name.

Maximum character length:

You can also specify a maximum number of characters to display by using this format:

  • format="length:number_of_characters"
For example, to display a maximum of ten characters you would specify the following parameter:

  • format="length:10"
compute=" " This is only applicable to menu, navigator and taxonomy components. You specify compute="always" when you reference some JSP code within a component design, and you want that code to be run separately on each result returned by a menu, navigator and taxonomy component.

For example, if a menu referenced JSP code that used the public DocumentId getCurrentResultId(); method, you would use compute="always" to make the JSP code run separately in every result returned by the menu.

If not specified, then compute="once" is used which is the default method for delivering the results of menu, navigator and taxonomy components.

htmlencode=" " If htmlencode="true" the reserved HTML characters in the source will be converted into character entities. For example, '<' will be converted to '&lt;'. This is useful if you would like to prevent users adding malicious code, or if you want to prevent users changing the look and feel of their text using HTML. If not specified, the default setting specified in the WCMConfigService.properties file located in the was_profile_root/PortalServer/wcm/config/ directory is used. By default, this is set to "true":
cmpnt.htmlEncodeDefault=true
awareness=" " If awareness="true" then user names are displayed using the people awareness features. These features displays user names as hyperlinks that allow users to contact people with whom they might want to work. Wherever person links appear, users can click the link to display a menu of actions for collaborating (contacting and working) with the person named by the link. If you, as administrator, have also configured an IBM® Lotus® Sametime® server to work with WebSphere Portal Express, person links indicate whether a person is active, away, offline, or in a Do Not Disturb state.

People awareness will only work in content rendered using either a local or remote rendering portlet.

If not specified, then awareness="false" and people awareness is not used.

separator=" " This only used when referencing a user selection component. It is used to define what text or code will be rendered between each selection. For example, to add a line break between each selection, you would use separator="<br>" . If not defined, a comma will be placed between each selection when rendered.
/> This closes the tag.
