Usage
*
*
* $tablefield = new HasOneComplexTableField(
* $this,
* 'MyOnlyFruit',
* 'Fruit',
* array(
* 'Name' => 'Name',
* 'Color' => 'Color'
* ),
* 'getCMSFields_forPopup'
* );
*
*
* **Notice** : You still have different ways to customize the popup window as in the parent-class [ComplexTableField](ComplexTableField).
*
* This field is made to manage a **has_one** relation. In the SilverStripe relation between DataObjects, you can use this relation for **1-to-1** and **1-to-many** relations.
* By default, a HasOneComplexTableField manages a **1-to-many** relation. If you want to specify that the relation that you manage is a **1-to-1** relation, add this code :
*
*
* $tablefield->setOneToOne();
*
*
* @package forms
* @subpackage fields-relational
