/**
* Checks for the existance of a property value by name or a control by ID.
* This overrides the parent implementation by allowing checking for the
* existance of a control via its ID using the following syntax,
* <code>
* $menuBarExists = isset($this->menuBar);
* </code>
* Do not call this method. This is a PHP magic method that we override
* to allow using isset() to detect if a component property is set or not.
* Note, the control must be configured in the template
* with explicit ID. If the name matches both a property and a control ID,
* the control ID will take the precedence.
*
* @param string the property name or control ID
* @return bool wether the control or property exists
* @see __get
