In a 8.51 FP3 enviroment we are experiencing some very strange effects that design changes do not become visible in the Notes Client. We have a XPages application designed to run in the Notes Client. Using Firefox (or any other browser) the application runs perfectly. However accessing it through the Notes Client it's showing a design (technical not CSS) which is weeks old!
In order to find the problem, we build a new database from scratch, created an XPages with only the text 'test' on it an on first open it works. However from then on changing the XPage (meaning the text) shows absolutely no effect. Always the application is still showing the text 'test'.
We first thought that maybe it has to do with the proxy settings the Notes Client is using. But adding 127.0.0.1 to the 'No proxy for these hosts or domains' setting did not change anything.
After a lot of testing we found out that deleting the cache.ndk file in the client data directory would result in any XPage application opened afterwards being updated once. However from the on that design would be shown regardless of any design changes being done afterwards. Deleting the cache.ndk all the time is not really an option for us.
I would be thankful if someone could guide me in the right direction what the cause of this problem is.
