Methods

allowInvalidSelections(bAllowInvalidSelections)

Whether the selection field displays a validation error if the selected #value is not a member of the #options array.

Invalid selections cause validation errors by default, but this may not always be the desired behaviour, for example if the SelectionField is being displayed using a combo-box, where the #options are acting merely as suggestions, rather than as the absolute set of options.

Parameters:
Name Type Description
bAllowInvalidSelections boolean Invalid selections are allowed when set to true.
Inherited From:

automaticallyUpdateValueWhenOptionsChange(bAutomaticallyUpdate)

Whether the selection field automatically picks a new #value when the underlying #options change.

If the underlying #options change, so that the new list of #options no longer includes the currently selected #value, a validation error will be displayed by default. In some circumstances, it may make sense to have the selection field automatically pick a new value automatically.

Parameters:
Name Type Description
bAutomaticallyUpdate boolean

getPath()

Returns the path that would be required to bind this node from the view.

This method is used internally, but might also be useful in allowing the dynamic construction of views for arbitrary presentation models.

Inherited From:

nodes(sNodeName, vProperties)

Returns all nested nodes matching the search criteria reachable from this node.

Care is taken not to search up the tree in cyclic presentation models (where some of the presentation nodes have back references to presentation nodes higher up in the tree).

Parameters:
Name Type Description
sNodeName String The name of nodes to match.
vProperties Object Only nodes having this array or map of properties will be matched.
Inherited From:
See:

properties(sPropertyName, vValue)

Returns all nested properties matching the search criteria reachable from this node.

Care is taken not to search up the tree in cyclic presentation models (where some of the presentation nodes have back references to presentation nodes higher up in the tree).

Parameters:
Name Type Description
sPropertyName String The name of properties to match.
vValue Object The value of properties to match.

removeAllListeners()

Deprecated:
  • This method has been replaced by #removeChildListeners which recurses the node tree. Removes all listeners attached to the properties contained by this PresentationNode.

    removeChildListeners()

    Removes all listeners attached to the properties contained by this PresentationNode, and any nodes it contains.
