WOToManyRelationship



Component Description

The WOToManyRelationship component displays a set of possible destination objects of an enterprise object's to-many relationship, allows the user to select a subset of the destination objects, and sets the enterprise object's relationship accordingly. It displays the possible destination objects of the relationship in a browser or as a set of checkboxes. This component must be embedded within a WOForm.


Synopsis

WOToManyRelationship { [uiStyle="checkbox"|"browser";] sourceObject=anObject; sourceEntityName=aString; relationshipKey=aString; [destinationDisplayKey=aString;] [isMandatory=aboolean;] [maxColumns=aNumber;] [size=aNumber;] [datasource=aDataSource;] };

Bindings

uiStyle
The type of user interface. Defaults to "checkbox" when the WOToManyRelationship component displays five or fewer objects. Otherwise defaults to "browser".
sourceObject
The enterprise object whose relationship is modified. A display group's queryMatch dictionary is also a valid source object. This allows you to query for objects having a particular to-many relationship.
sourceEntityName
The name of the entity that is modified.
relationshipKey
The name of the relationship that is modified.
destinationDisplayKey
A displayable attribute of the relationship's destination objects. Defaults to "userPresentableDescription".
isMandatory
A flag to indicate that a selection is necessary. Defaults to NO.
maxColumns
The maximum number of columns in the checkbox array. Used only when the user interface style is "checkbox".
size
The maximum number of rows in the browser. Used only when the user interface style is "browser".
dataSource
A data source for the relationship's destination objects. By default, the WOToManyRelationship component creates an EODatabaseDataSource containing all possible destination objects. However, if you want to limit the number of destination objects the user can choose, you can create your own EODatabaseDataSource that has a subset of the possible destination objects and bind it to this attribute.
