actually i want to come out with a frame which have 2 views(each view tie to their respective document-b'cos the data shown on one view is different from the others). these views are only shown when the user requests it. however these 2 views are able to keep refreshing(real-time) their content(document data) when they are hidden or showing.
(note : currently i only have one frame with one view one document. And the view are able to data refresh in real-time)
