Resource Allocation Chart/Grid: New Resource Allocation > Select Project Task > Click OK > No Response

SuiteApp/Bundle:  Resource Allocation Chart/Grid 

When the Users are trying to create New Resource Allocation via Resource Allocation Chart/Grid page, after they input all the mandatory field and click OK, nothing happens when clicking the ok button. However, when you tried to check the error console (press F12), it shows error message 'Uncaught TypeError: Cannot read property 'getTime' of null'

Update the preference through these steps:

1. Go to Set up > Company > General Preference
2. Set the MAXIMUM ENTRIES IN DROPDOWNS = 1
3. Click Save

Note: As long as the MAXIMUM ENTRIES IN DROPDOWNS is more than zero the issue is no longer reproducible.
