We are working on a modal which allows the user to edit Task as well as Event record from a grid view. We are using
lightning:recordEditForm to show record edit view but for some reason, all we get is blank white screen in the modal.
We tried to use
lightning:recordEditForm to edit record for a custom object record also for some standard object such as Account, Contact.. it works fine.
As a matter of fact, I believe that lightning:recordEditForm uses Lightning Data Service internally, so looking at its current limitation it does not support Task and Event.
Not sure if my assumption is right? or Has anyone experienced this issue?
NOTE : We are trying to show the modal in LEX
