We are planning to use Portal Eventing between Webdynpro ABAP and BSP iView in portal. The idea is to retrieve the data from database using WD ABAP and then pass some parameters to the BSP iview which will then point some locations on a map!. The problem is, everytime the parameters are getting passed from WD to BSP the BSP frame gets refreshed and we do not want that to happen!! Is there any other way of not having to refresh the frame whilst using Portal eventing. If not what is the other way of doing it? I would greatly appreciate your help. Thanks a lot.
