it is reproducible in your live demos as well.
i notice this while i create new task or existing task.
1. as per db table, start date and end date can not be null.
currently as i created new task. the default will be today's start date and end date.
task 1 - start date - 05/14/2015 end date - 05/14/2015
my expectation - start date - 07/01/2015 and end date -10/15/2015.
in this scenario- first i change the start date to 07/01/2015. it wont let me do it because its bigger than default end date(05/14/2015)
so i change first end date to -10/15/2015 then change start date - 07/01/2015
as soon as i change start date - 07/01/205 the end date automatically gets change to some random date 11/13/2015(something like that). so again i have to change the end date to desire one.
i just checked it in live demo. it is happening there too. please help. i need to fix it ASAP.
