[ANGULAR] Unassigned event disappears when dragged to same time/date as original schedule

[tomas@between.as]

Hi Bryntum team,

I’ve run into a strange issue when working with unassigned events in the calendar.

When I drag an unassigned event onto the calendar and drop it exactly on the same date and time as it was originally scheduled for, the event disappears. However, if I drop it on a different time on the same day, or on a different day, everything works fine.

I’ve attached a short video showing the behavior to make it clearer.

Is this expected behavior, or could it be a bug or misconfiguration?

Thanks in advance for the help!

Hi,

Looks weird, could you please share a runnable test case so we can check what's wrong? Are you able to reproduce it with our online demo here https://bryntum.com/products/calendar/examples/dragfromgrid/?

You have to drop different event records. Looks like the same record being moved twice. Can you show us source Javascript code and the data?

This works fine out of the box in this example though: https://bryntum.com/products/calendar/examples/dragfromgrid/

Just set removeFromExternalStore to false to make it create a new event on each drag in, and each new event is assigned to the resource dropped in:
