Embedded Objects - Entities

An object of type entities is an EntityListBackingBean with a pageable list of persisted entities. For example, embed full-time employees hired after May 18, 2010, ordering by employee id, 30 employees per page:


	<object xmlns="http://www.cmobilecom.com/af/objects"
			id="employees" type="entities">
		<entityType>HR.EMP</entityType>

		<criteriaElements>
			<function name="EQ" property="type">FULL_TIME</function>
			<function name="GE" property="hiredDate">2010-5-18</function>
			<asc property="nid"/>
		</criteriaElements>

		<viewConfig>
			<viewType>ENTITY_LIST_WIDE</viewType>
			<pageSize>30</pageSize>
			<propertiesToShow>nid,name,hiredDate</propertiesToShow>
		</viewConfig>

	</object>

The criteriaElements is used to create query criteria to retrieve entity list from persistence.

The viewConfig parameter entity.not.found describes what to do if the entity list is empty.


	<viewConfig>
		<viewType>ENTITY_LIST_WIDE</viewType>
		<param name="entity.not.found" value="ignore" /> 
	</viewConfig>

Parameter: entity.not.found. (default: keep)

ignore: the embedded object is null (not visible) without showing any message.
keep: the embedded object is an EntityListBackingBean with empty list of entities.
