Clearing a Date Field value in the Edit Node form I have a content type with a date field (field_acquisition_date) and I'm using the Popup Calendar widget in the form UI. If a user...


puts a value into that field and save the node
then edits the node again
clears out the value
and saves the node a second time


the original value is still in that date field. How can the user set that field value to empty/NULL while using the edit form?
You just need to set the default value to 'No default value' in the content type of where the field is created. 

Please see in the screenshot
