Examples of org.apache.tiles.evaluator.el.ELAttributeEvaluator

org.apache.tiles.evaluator.el.ELAttributeEvaluator
Evaluates string expression with typical EL syntax.
You can use normal EL syntax, knowing that the root objects are {@link TilesRequestContext}, {@link TilesApplicationContext} and beanscontained in request, session and application scope. @version $Rev: 734389 $ $Date: 2009-01-14 14:38:06 +0100 (mer, 14 gen 2009) $ @since 2.1.0
