When the popup window is displayed, the current window contents become "greyed out" and the new window appears on top of the original. The original window does not respond to keys or clicks; only the new window can be accessed by the user. When the popup window is closed then the original window is again accessable.
When this component has a child facet named "titleBar" then the contents of that facet are rendered at the top of the popup window. This facet is intended to allow users to define their own custom window "decoration".
When this component has no "titleBar" facet, but does have a "dialogTitle" property, then a default window decoration is generated. It consists of a table row with two cells. The left cell contains the dialogTitle text. If property renderCloseButton is true, then the right cell holds a "close" icon. Styles are defined for the row and cells so that the look-and-feel can be customised.
The new window can optionally load a page from the server when it is displayed. If one of viewId or contentURL is defined, then an internal frame is inserted after the titleBar, and the specified contents is immediately loaded into the popup window when it is displayed.
The rest of the child components (ie other than titleBar) are displayed after the titlebar (and after the contents of viewId or contentURL if it is defined).
This component internally uses the Dojo modal window widget.

| Attributes | ||||
| Name | Required | Request-time | Type | Description |
| dialogAttr | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| A space separated list with attribute='value' pairs, which control the behaviour of the dojo dialog. |
| dialogId | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| An optional raw id to assign to the html div that encloses the modal dialog.
This id can be useful for controlling the dialog with javascript. However in most cases it is not necessary. If this is property is not defined then an id will be automatically generated. |
| dialogVar | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| Specifies the name of the javascript variable which provides access to the
dialog functionality.
For example, if this is "myDialog" then a javascript object with name "myDialog" will be defined. This exposes the following methods:
|
| hiderIds | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| A list of ids of components which, when activated, should cause the popup
dialog to be hidden.
If the standard title-bar is displayed (ie no custom titleBar facet exists, and property dialogTitle is defined) then the standard close-button in that bar is automatically included. If the child components of this component (which will appear in the popup) include other items that should cause the window to close (ie a button) then their ids should be defined via this property. This component will then automatically wire them up to the necessary functions to cause the popup to be closed when they are activated. |
| viewId | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| The URL of the view to show within the content area of the dialog.
Optional; when not defined (or defined as an EL expression, but that expression returns null) then the popup dialog will be opened with no content. Presumably custom javascript in the calling page will arrange to populate the window content appropriately. The modalDialog component treats this as a url relative to the webapp base. The value should not start with a slash. Note that technically this value is not a viewId. A viewId is the internal path to the page definition (eg "foo.jsp" or "foo.xhtml"). What the browser accesses is a URL (which contains the path that triggers the facelets servlet, eg "foo.faces" or "foo.jsf" or "/faces/foo". The valueIt should not start with a slash. |
| contentURL | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| The URL to show within the content area of the dialog.
This may be:
|
| style | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| HTML: CSS styling instructions. |
| styleClass | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| The CSS class for this element. Corresponds to the HTML 'class' attribute.
This value is also used as a base for defining style classes for parts of the standard window "title bar" decoration. |
| widgetId | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| Optional enforced dojo widgetId |
| dialogTitle | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| The title text to show in the title area of the popup window
(ie the "window decoration").
Ignored if there is a "titleBar" facet as a child. |
| closeButton | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Boolean)
| Specifies whether there should be a "close" icon to the right of the
popup window title.
Ignored if there is a "titleBar" facet as a child, or dialogTitle is not defined. Defaults to true. |
| widgetVar | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| An alias for the "dialogVar" property. |
| id | false | true | java.lang.String | Get a string which uniquely identifies this UIComponent within the scope of the nearest ancestor NamingContainer component. The id is not necessarily unique across all components in the current view. |
| rendered | false | false | javax.el.ValueExpression
(must evaluate to boolean)
| A boolean value that indicates whether this component should be rendered. Default value: true. |
| binding | false | false | javax.el.ValueExpression
(must evaluate to javax.faces.component.UIComponent)
| Identifies a backing bean property (of type UIComponent or appropriate subclass) to bind to this component instance. This value must be an EL expression. |
| Variables | No Variables Defined. |
