Created attachment 155315 [details] Screenshot of the dissociated event in Kontact/Korganizer and the corresponding calendar widget entries SUMMARY The PIM events plugin in the digital clock widget shows events twice after dissociation from the event series - once as part of the event series and once as single event. STEPS TO REPRODUCE 1. Configure the Plasma digital clock widget to use the PIM events plugin for the calendar: Right-click on the digital clock widget -> "Configure Digital Clock..." > "Calendar" > "Available Plugins" > tick checkbox for "PIM Events Plugin". 2. Configure the PIM events plugin to use your calendar: Still in "Digital Clock Settings" > "PIM Events Plugin" > tick checkbox for your calendar > "OK". 3. Apply your changes by clicking on "Apply" and "OK". 4. Create a new event in Korganizer ("New Event...") and configure it as recurring event (tab "Recurrence"- I chose "Repeats" > "Weekly") and save it with "Apply" and "OK". 5. Dissociate one event of the recurring event (series) by choosing one event of the series with by right-clicking on it and click on the "Dissociate from Recurrence..." context menu entry. If Korganizer asks for confirmation, hit "Dissociate". 6. Open the settings of the newly dissociated event by right-clicking on it and choosing "Edit...". 7. Edit the time and/or date for the newly dissociated event (right-click on event -> "Edit...") and save your changes. 8. Open the calendar of the digital clock widget by left-clicking on it and choose the day of the dissociated event. OBSERVED RESULT The dissociated and modified event is now displayed twice in the calendar of the digital clock widget - as a recurring event and as a dissociated event. EXPECTED RESULT The event that is now dissociated from the recurring event (series) should only be visible once in the calendar of the digital clock widget and should not be displayed a second time as part of the recurring event. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: KDE neon 5.26 and Arch Linux (rolling) (available in About System) KDE Plasma Version: Both 5.26.5 KDE Frameworks Version: Both 5.101.0 Qt Version: Both 5.15.8 ADDITIONAL INFORMATION I'm not really sure if the bug is related to the PIM events plugin or to Korganizer's. Do they treat recurring and dissociated events in the same way? I'm wondering if the series of events internally/database-wise consists out of single events or if the series is treated as one single object for both of them.
