I love to develop Lotus Notes applications, but sometimes…
Two hours ago I was very frustrated. Some time ago I created a new agent in a Lotus Notes database. I wrote the code and during a Sametime chat, my Domino Designer crashed. I restarted the Designer, but all of my code in the agent was lost. I started to re-implemented the code. I do not know why, but after several lines of code, I have closed the Designer and re-opened it. Then, I wrote some more lines of code. Some times later, my Designer crashed again. I restarted the Designer and all the new code since the last restart of the Designer was lost… 😦 I have saved the code several times before the Designer crashed, since I run the agent several times to test it. I had never before this situation. Normally, I implement the code in a library and do not use an agent interface. But I’m wondering why the saved code was lost after the crash. It is possible that the Domino Designer uses an internal cache?

Please try and restart Windows. Your code should then re-appear.

Thank you for your suggestion.

You may be able to see it by closing Notes/Designer, then ending the “nnotesmm.exe” task. Or restarting Windows, as Bruce says. But you may also be out of luck. There is a corruption problem with the LS editor in 8.5.3 that CAN destroy your code. So you might be stuck. I had a developer lose an entire day’s work on an agent, and they had saved many times throughout the day. Rumor is it’s fixed in 8.5.4.

Thanks for your hint.

This has happened to me a few times now. It is really infuriating. I’ll try restarting Windows next time.
