When editing the attribute table of a shapefile in QGIS (2.14.8 ltr) using a value relation field (one or multiple choices) in formular view, hitting
Ctrl-A selects all attribute table entries; subsequently hitting
Delete deletes all content - geometry and attributes. There is no warning. There is no way to restore the entry besides turning off the editing mode without saving your changes.
I'm not even sure if this is intended behaviour. Anyone knows a way to prevent that?
FTR, I also lost single entries by hitting
Backspace when entering data, and this inspired my post. However, I couldn't reproduce this on purpose, but if I find out how, I'll come back to this post for an update.
