Reloads the parameter definitions for the call. It allows to automatically retrieve the RODL from the RemoteService and locate the operation based on the MethodName.

procedure RefreshParams(aPersistValues: Boolean)

Parameters:

• aPersistValues: Allows to persist any values.

---

Links to a TRORemoteService component that defines the service to be called.

property RemoteService: TRORemoteService read write
