Implementing user interactions
With Digital Data Connector (DDC) for HCL Portal, you can use HCL Web Content Manager presentation components for visualizing external data. As a further benefit, you can also add user interfaces for creating, modifying, and deleting external data to your DDC list appearance components. This way, your users can use these features to create, modify, or delete external data items from your lists.
In this scenario, the Web Content Viewer portlet acts as a mediator. It forwards information provided by the user to the specified data sink and sets the result information either as a private render parameter or as a session attribute. You can plug in your own data sinks by implementing the com.ibm.portal.resolver.data.FormDataDataSink interface. This interface is defined in the public POC resolution framework API. For more detailed information, refer to the Package com.ibm.portal.resolver.data summary.
