When you are viewing an object marked as container in Adaxes Web Interface, the main Web Interface view displays child objects of the object no matter of its type. In case of an object that is not marked as container, properties of the object are displayed. This applies to all object types, meaning that if you clear the Container checkbox for Organizational Unit Object type, you will not be able to see objects located in OUs. The Web Interface will only display properties of OUs.
The dialog box of the View <Object> action is designed specifically to display properties of objects (including containers). Trying to display container objects via the action in the main Web Interface view would lead to logical issues as the main Web Interface view displays child objects for containers while the action has to display properties of the selected object.
