My lightning component's controller has an array named newResources and using aura:iteration to show a table based on the values in it. There is a method in js "removeNewResourceColumn" which removes one element from that array and then the aura:itration updates the view with one less row but when the method removes the last element of array the aura iteration view is not getting updated.

E.g. If I have 8 records in the array then the table will show 8 rows. If removeNewResourceColumn removes 6th element the table will show 7 records but if removeNewResourceColumn removes 8th element the table still shows 8 records.
Has anyone ever faced this problem?
