Description mail 2020-05-09 08:23:32 UTC

STEPS TO REPRODUCE
1. create a new calandar event 
2. cerate a new category for this event (annoying UI for this) or select an existing category
3. revisit the event and _deselect_ the category

--> "Error while trying to modify calendar item. Error was: Akonadi:Exception: No objects specified"

EXPECTED RESULT
Event should be modified and show no category selected after saving the modification.

If there are more than one category I can deselect categories under the condition there is still one category left as ticked.


SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 
I tried the manjaro-kde-20.0-200426-linux56.iso
and the neon-user-20200507-1116.iso in VirtualBox 6.1.6
It is bugging me on Manjaro Stable installed on AMD64 hardware.

KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.69.0
Qt Version: 5.14.2

ADDITIONAL INFORMATION
Did also not work last week before the upgrade to Plasma 5.18.5

Comment 1 mail 2020-09-09 06:02:22 UTC

can still reproduce it in these versions:

KDE Plasma 5.19.5
KDE Frameworks 5.73.0

Comment 2 Allen Winter 2020-09-15 22:25:13 UTC

verified.
also this nit: the uneditable category line edit contains "Click to add tags".  which is untrue.  clicking in the line edit does nothing.

Comment 3 Allen Winter 2020-09-19 14:27:59 UTC

reassign this to akonadi
