The "definition" element describes a definition that can be inserted in a jsp page. This definition is identified by its logical name. A definition allows to define all the attributes that can be set in <insert> tag from a jsp page.

Element identifier.

Possible values: Match the ID rules.

The fully qualified Java class name of the preparer subclass to call immediately before the tiles is inserted. Only one of preparerClass or preparerUrl should be specified.

Name of a definition that is used as ancestor of this definition. All attributes from the ancestor are available to the new definition. Any attribute inherited from the ancestor can be overloaded by providing a new value.

Security role name that is allowed access to this definition object. The definition is inserted only if the role name is allowed.

The context-relative path to the resource used as tiles to insert. This tiles will be inserted and a tiles context containing appropriate attributes will be available.

The expression that will evaluate to a template for this definition. This attribute will be ignored if template is specified.

The type of the template attribute. Can be: string, template or definition. By default, the type is "template". If a type is associated, the desidered renderer will be invoked.

The "put-attribute" element describes an attribute of a definition. It allows to specify the tiles attribute name and its value. The tiles value can be specified as an xml attribute, or in the body of the <put-attribute> tag.

Possible values: Match the ID rules.

The unique identifier for this put-attribute.

Required

The type of the value. Can be: string, template or definition. By default, no type is associated to a value. If a type is associated, it will be used as a hint to process the value when the attribute will be used in the inserted tiles.

The value associated to this tiles attribute. The value should be specified with this tag attribute, or in the body of the tag.

The expression associated to this tiles attribute. This attribute will be ignored if value is specified.

Security role name that is allowed access to this attribute object. The attribute is inserted only if the role name is allowed.

If true, the attribute will be cascaded to all inner definitions. By default, cascade is false.

Possible values: true, false

The "put-list-attribute" element describes a list attribute of a definition. It allows to specify an attribute that is a java List containing any kind of values. In the config file, the list elements are specified by nested <add-attribute>, <item> or <add-list-attribute>.

Element identifier.

Possible values: Match the ID rules.

The unique identifier for this put attribute list.

Required

Security role name that is allowed access to this attribute object. The attribute is inserted only if the role name is allowed.

If true, the attribute will put the elements of the attribute with the same name of the parent definition before the ones specified here. By default, it is 'false'.

Possible values: true, false

If true, the attribute will be cascaded to all inner definitions. By default, cascade is false.

Possible values: true, false

The "add-attribute" element describes an element of a list. It is similar to the <put> element.
