annotation : stringa1 ... aN: empty annotation names; must differ from domain model attribute namesattributes : stringAdditional association paths to retrieveaugment : uiIdentifierA path to the view to augment with this view. Augmentation rules depend on the types of augmented and augmenting views. When augmented view is a layout, such as Composite, Tabs, or Switch, and augmenting view is also of the same type, the children views will be added to the augmented layout. When both augmented views are layouts but of different type, the augmenting view is inserted next to the augmented one. When augmented view is primitive, the augmenting view is inserted next to it.

[<class>]'<event> <arg1> ... <argN>Specification: [<class>]'<event> <arg1> ... <argN> <class> is an optional class symbol. When omitted, the items collection class is used. <event> is a read event symbol. <arg#> is an event argument value which can be either a constant or a scheme expression evaluating to a constant at run-time on the client, using special local variables provided by the framework: this (=controller), :node (=active node), :attributes, :where, :orderBy, :count, :offset, :xlock, or a UI initializer variable. If arguments are not specified, a default list is supplied by the framework: :attributes :where :orderBy :count :offset :xlock Examples: a) Generate a request to 'readList event with default arguments: readList b) Generate request to readList event with attributes, and orderBy argument values supplied by the framework. readList :attributes :orderBy c) Generate request to Contact'readDetail with attributes supplied by the framework, and the contact argument calculated using (current-contact) client library function. Contact'readDetail :attributes (current-contact this :node) In a library: (define (current-contact controller node) ... ) d) Generate request to 'read event with a constant attribute list: read '(lastName firstName) :where :orderBy :count :offset :xlockref : stringPicker (.picker) definition nameshowGroupCounts : booleanTrue if the List should show the group size in the headersort : ComboSortTypeSet to "server" to perform sort on the server, "client" to perform sort on the client when order expression is not supported by the data sourceValid values based on“string”.clientThe model will be sorted on the client.serverThe model will be sorted on the server.span : intNumber of consecutive columns to occupyvalues : identifierListAssociation path or expression to the value returned from the items in the collectionIf blank, the value will be the object itself - not an attribute on the object. Note that this property isn't a list of values. It is simply the association path, or expression, to the return value of the items.
