ESS/MSS Web Dynpro iviews - blank screen - missing iview properties
Many of our ESS/MSS iviews have stopped working and are just showing a blank screen. The ESS, MSS and Area Overview pages ARE working, but any of the links (e.g. Who's Who, Change Own Data, Record Working Time) just give a blank screen (no error message).
They were working, then I made some changes in the IMG (I added a couple of custom Services to one of the Area pages). All the links (other than the ones I had added) then stopped working - I thought the problem was as described in SAP note 808111 so I copied all the Resources "URL of PCD page" from client 000. The PCD page URLs are now in place and correct, however I am still getting blank screens.
I have tried previewing the actual WD iviews and they also give blank screens. When I look at the iview properties, there is no "Application Name" property and other Web Dynpro properties are missing too - that is to say, the actual parameter is missing completely, not just that the field is blank. I have seen one other person mention this on another thread but he did not have a solution (ESS / MSS issue).
Any help greatly appreciated.
