Use AdapterDispatcher to get or set the interface of the adapter dispatcher. The adapter dispatcher is responsible for encoding the hidden fields and HREF values that represent calls to adapter fields and actions, and for interpreting the fields in incoming requests by calling adapters to execute their actions or to fetch image field values. 

Typically, AdapterDispatcher is the interface of a TAdapterDispatcher object. If the WebSnap application does not include a TAdapterDispatcher component, or some other component that implements the IAdapterDispatcher interface, the value of this property is nil (Delphi) or NULL (C++). When AdapterDispatcher is nil (Delphi) or NULL (C++), the WebSnap application can't execute adapter actions or fetch image fields from adapters.
