In portal.properties, can a hook plugin insert a new class between DefaultLandingPageAction and LoginPostAction?

In Liferay, the order of execution for actions like those in the login flow is critical to the overall behavior of the portal. The hooks enable developers to customize certain features and behaviors within Liferay's architecture; however, they are bound by specific constraints regarding how and where they can insert their custom classes.

In this case, a hook plugin cannot insert a new class between DefaultLandingPageAction and LoginPostAction because these classes are part of the predefined execution order within the login mechanism of Liferay. The framework does not allow modification of this order through hooks or any external class insertion in between existing actions. Instead, any custom logic typically needs to flow through established mechanisms, such as overriding or extending existing functionalities without directly interrupting the sequence of these actions.

This limitation ensures the integrity of the login process and maintains a consistent user experience across different instances of the portal. Customizations are usually done by creating filters or overriding the entire class when extending functionalities aligns more with the architecture's design principles.
