The component for ordered lists rendering that allows choosing data from a model and obtains built-in support of Ajax updates.
A completely skinned list and child elements
Possibility to update a limited set of rows with AJAX
Possibility to receive values dynamically from a model
Table 6.166. rich : dataOrderedList attributes
Attribute Name | Description |
---|---|
ajaxKeys | This attribute defines row keys that are updated after an AJAX request |
binding | The attribute takes a value-binding expression for a component property of a backing bean |
dir | Direction indication for text that does not inherit directionality. Valid values are "LTR" (left-to-right) and "RTL" (right-to-left) |
first | A zero-relative row number of the first row to display |
id | Every component may have a unique id that is automatically created if omitted |
lang | Code describing the language used in the generated markup for this component |
rendered | If "false", this component is not rendered |
rowClasses | A comma-delimited list of CSS style classes that is applied to popup table rows. A space separated list of classes may also be specified for any individual row. The styles are applied, in turn, to each row in the table. For example, if the list has two elements, the first style class in the list is applied to the first row, the second to the second row, the first to the third row, the second to the fourth row, etc. In other words, we keep iterating through the list until we reach the end, and then we start at the beginning again |
rowKey | RowKey is a representation of an identifier for a specific data row |
rowKeyConverter | Converter for a RowKey object. |
rowKeyVar | The attribute provides access to a row key in a Request scope |
rows | A number of rows to display, or zero for all remaining rows in the table |
style | CSS style(s) is/are to be applied when this component is rendered |
styleClass | Corresponds to the HTML class attribute |
title | Advisory title information about markup elements generated for this component |
type | Corresponds to the HTML OL type attribute |
value | The current value for this component |
var | A request-scope attribute via which the data object for the current row will be used when iterating |

Name | Value |
---|---|
component-type | org.richfaces.DataOrderedList |
component-class | org.richfaces.component.html.HtmlDataOrderedList |
component-family | org.richfaces.DataOrderedList |
renderer-type | org.richfaces.DataOrderedListRenderer |
tag-class | org.richfaces.taglib.DataOrderedListTag |
To create the simplest variant of dataOrderedList on a page, use the following syntax:
Example:
...
<rich:dataOrderedList var="car" value="#{dataTableScrollerBean.allCars}" >
<h:outputText value="#{car.model}"/>
</rich:dataOrderedList>
...
Example:
import org.richfaces.component.html.HtmlDataOrderedList;
...
HtmlDataOrderedList myList = new HtmlDataOrderedList();
...
The <rich:dataOrderedList> component allows to generate an ordered list from a model.
The component has the "type" attribute, which corresponds to the "type" parameter for the <OL> HTML element and defines a marker type. Possible values for "type" attribute are: "A", "a", "I", "i", "1".
Here is an example:
...
<h:form>
<rich:dataOrderedList var="car" value="#{dataTableScrollerBean.allCars}" rows="5" type="1" title="Car Store">
<h:outputText value="#{car.make} #{car.model}"/><br/>
<h:outputText value="Price:" styleClass="label"></h:outputText>
<h:outputText value="#{car.price}" /><br/>
<h:outputText value="Mileage:" styleClass="label"></h:outputText>
<h:outputText value="#{car.mileage}" /><br/>
</rich:dataOrderedList>
</h:form>
...
This is a result:
In the example the "rows" attribute limits number of output elements of the list.
"first" attribute defines first element for output. "title" are used for popup title.
The component was created basing on the <a4j:repeat> component and as a result it could be partially updated with Ajax. "ajaxKeys" attribute allows to define row keys that are updated after an Ajax request.
Here is an example:
Example:
...
<rich:dataOrderedList value="#{dataTableScrollerBean.allCars}" var="car" ajaxKeys="#{listBean.list}"
binding="#{listBean.dataList}" id="list">
...
</rich:dataOrderedList>
...
<a4j:commandButton action="#{listBean.action}" reRender="list" value="Submit"/>
...
In the example "reRender" attribute contains value of "id" attribute for <rich:dataOrderedList> component. As a result the component is updated after an Ajax request.
For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.
There are two ways to redefine the appearance of all <rich:dataOrderedList> components at once:
Redefine the corresponding skin parameters
Add to your style sheets style classes used by a <rich:dataOrderedList> component
On the screenshot there are classes names that define styles for component elements.
Table 6.168. Classes names that define a list appearance
Class name | Description |
---|---|
rich-orderedlist | Defines styles for an html <ol> element |
rich-list-item | Defines styles for an html <li> element |
In order to redefine styles for all <rich:dataOrderedList> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above ) and define necessary properties in them.
Example:
...
.rich-orderedlist{
background-color: #ebf3fd;
}
...
This is a result:
In the example background color was changed.
Also it's possible to change styles of particular <rich:dataOrderedList> component. In this case you should create own style classes and use them in corresponding <rich:dataOrderedList> styleClass attributes. An example is placed below:
Example:
...
.myClass{
font-style: italic;
}
...
Example:
<rich:dataOrderedList ... styleClass="myClass"/>
This is a result:
As it could be seen on the picture above, the font style was changed.
On the component LiveDemo page you can see the example of <rich:dataOrderedList > usage and sources for the given example.
