addFields(List<String>)
When a Visualforce page is loaded, the fields accessible to the page are based
on the fields referenced in the Visualforce markup. This method adds a reference to each field specified
in fieldNames so that the
controller can explicitly access those fields as well.
Signature
public Void addFields(List<String> fieldNames)
Parameters
- fieldNames
- Type: List<String>
Return Value
Type: Void
Usage
This method should be called before a record has been loaded—typically, it's called by the controller's constructor. If this method is called outside of the constructor, you must use the reset() method before calling addFields().
The strings in fieldNames can either be the API name of a field, such as AccountId, or they can be explicit relationships to fields, such as foo__r.myField__c.
This method is only for controllers used by dynamicVisualforce bindings.
