Indexed Properties
Some beans have properties that are Java arrays or lists. You can therefore add an index subscript to a property name in order to specify which element in the list you want to access. The following expression, for example, returns the name of the first author of an article:
${article.authors[0].name}
(Note that this returns exactly the same value as the second example
in Accessing Bean Properties. The
authors
property returns an array containing
all of a content item's authors; the
author
property returns the first member of the
array, just like this example.)
