I don’t know if that is a bug or just how Hide events work. But a show event works upon toggling from not visible to visible. But the Hide event only seem to work when the parent of the container or the whole form disappears.
Did you ever find a workaround? I’m trying to get the hide event to trigger when I make a component invisible, but running into the same issue of it not triggering.
I don’t have a workaround (though maybe you could do something with JavaScript?) but I’m going to at least change this thread to a Feature Request (though it’s really a bug report, I think).
