I am not a developer so whenever I dig into code things get ugly (especially with Notes). On my forms I tend to add action buttons to switch to the next and previous documents. I use the nice command
@Command([NavigateNext]) (and previous)
Unfortunately the onChange event does not get fired if I use this kind of navigation. Entering events work, exiting events do not.
And by the way. I love it if I find old topics on Notes.net that describe a similar problem in 2003 and years later it is still there. Yes I know the old legacy stuff hardly ever get fixed but I still have to use it from time to time.
