<c:choose>
<c:when test=”${deviceClass == 'desktop'}”>
<jsp:forward page=”/jsp/html/desktop/View.jsp”/>
</c:when>
<c:when test=”${deviceClass == 'tablet'}”>
<jsp:forward page=”/jsp/html/tablet/View.jsp”/>
</c:when>
<c:otherwise>
<jsp:forward page=”/jsp/html/View.jsp”/>
</c:otherwise>
</choose>
The ContentNodeBean represents a node in the ContentModel.

This bean provides access to the tree model for the layout of a page. The nodes of the tree are objects implementing the LayoutNode interface. This model describes the layout of a page (row and column containers, LayoutContainer) and the content (controls representing portlets, LayoutControl).
layoutModel

Parameters: Node
Returns: iterator of layout nodes
Example:
${wp.layoutModel[node]}
The following displays an example of getting the layout model for the currently selected node from the selection model. The second line retrieves the children of the root mode of the layout model.
<c:set var="layoutmodel" value="${wp.layoutModel[wp.selectionModel.selected]}"/>
<c:set var="containers" value="${layoutmodel.children[layoutmodel.root]}"/>
children
Parameters: Node
Returns: children of the specified nodes
Example:
<c:set var="containers" value="${layoutmodel.children[layoutmodel.root]}"/>
hasChildren
