Attributes
| Name | Type | Supports EL? | Description |
|---|---|---|---|
| binding | String | Only EL | Identifies a backing bean property (of type UIComponent or appropriate subclass) to bind to this component instance. This value must be an EL expression. |
| detailFormat | String | Yes | If present, instead of rendering the message detail, a MessageFormat with this attribute as pattern is created. The format method of this MessageFormat is called with the message detail as the first argument and the label of the associated component (if any) as the second argument. Example: "The input in field {1} is wrong: {0}" |
| dir | String | Yes | HTML: The direction of text display, either 'ltr' (left-to-right) or 'rtl' (right-to-left). |
| enabledOnUserRole | String | Yes | If user is in given role, this component will be rendered normally. If not, no hyperlink is rendered but all nested tags (=body) are rendered. |
| errorClass | String | Yes | CSS class to be used for messages with severity "ERROR". |
| errorStyle | String | Yes | CSS style to be used for messages with severity "ERROR". |
| fatalClass | String | Yes | CSS class to be used for messages with severity "FATAL". |
| fatalStyle | String | Yes | CSS style to be used for messages with severity "FATAL". |
| forceId | boolean | No | If true, this component will force the use of the specified id when rendering. |
| forceIdIndex | boolean | No | If false, this component will not append a '[n]' suffix (where 'n' is the row index) to components that are contained within a "list." This value will be true by default and the value will be ignored if the value of forceId is false (or not specified.) |
| forceSpan | boolean | Yes | If set to true, an empty span element is rendered. Useful if there is an inputAjax field and the corresponding error message is displayed there. |
| globalOnly | boolean | Yes | A boolean value that controls whether global messages (those without IDs) should be displayed. Default: false. |
| globalSummaryFormat | String | Yes | Like summaryFormat, but applies to global messages (i.e. messages not associated with a component). If no globalSummaryFormat is given, the summaryFormat is used for global messages. Example: "{0}:" |
| id | String | Yes | An identifier for this particular component instance within
a component view.
The id must be unique within the scope of the tag's enclosing NamingContainer (eg h:form or f:subview). The id is not necessarily unique across all components in the current view This value must be a static value, ie not change over the lifetime of a component. It cannot be defined via an EL expression; only a string is permitted. |

| infoStyle | String | Yes | CSS style to be used for messages with severity "INFO". |

| rendered | boolean | Yes | A boolean value that indicates whether this component should be rendered. Default value: true. |
| replaceIdWithLabel | boolean | Yes | If present, all occurrences of the id of the component for which the message is rendered will be replaced by the label. Default: true. |
| showDetail | boolean | Yes | An EL expression, returning a boolean, that controls whether the detail text of the associated messages is displayed. Default: false. |
| showSummary | boolean | Yes | An EL expression, returning a boolean, that controls whether the summary text of the associated messages is displayed. Default: true. |
