parentMeta

If the Component is included in an Action, the Meta information of the Screen to which the Component belongs is the parent concept of the Component.

Similarly, if the Control is included in an Action, the Meta information of the Component to which the Control belongs is the parent concept of the Control. However, in the loadService of a Component, parentMeta refers to the Meta of the Component, just like Meta.

INFO

For example, if parentMeta registered in the Action of a Control, the Key would be the parent Meta of the Control, i.e., the Meta of the Component. In the case where the Action is registered in a Component, it signifies the Meta of the Screen.
You can set the name for the parameter corresponding to the Meta configured in the Key in the Parameter Key.
