Hi,
I get the following exception when adding a new task above a task with an invalid value within a column cell:
DOMException: Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted is not a child of this node.
Steps to reproduce in advanced example for 5.6.7:
Set start date field to required
Double click in the start date column cell of a task and delete the date value
Do a right click to open the task context menu
Add a new task above
Is there any fix available?
Thanks in advance.
