Description
The Choose component is used in conjunction with When and Otherwise components to express mutually exclusive conditional tests.

The Choose component must contain one or more When componets and can contain only one optional Otherwise component (which must occur after all of the When components). If the Choose component only contains one When element, then for all practical purposes, it behaves just like the Conditional component. When faced with three or more choices, this component behaves like a switch/case/default statement.

Each When component is examined in the order of occurrence. If and when the condition expression is satisfied the content in that component is rendered. Then all further When components are ignored. The optional Otherwise component is also automatically ignored. If none of the conditions in any When component is satisfied , then the Otherwise component is automatically selected (if it is present) and the content associated with that element is rendered.

• White spaces
  May appear anywhere around the When and Otherwise components.
• 1 or more When components
  Must all appear before Otherwise.
• 0 or 1 Otherwise component
  Must be the last component nested within Choose

For simple conditional testing, use the Conditional component.

The following sample code shows how the text rendered depends on a user’s membership category.

              <span jwcid="contrib:Choose>
                 <span jwcid="@contrib:When" condition='ognl:"visitor".equals(user.category)'>
                    ...
                 </span>
                 <span jwcid="@contrib:When" condition='ognl:"member".equals(user.category)'>
                    ...

                 <span jwcid="@contrib:When" condition='ognl:"customer".equals(user.category)'>
