Preconditions:

1.- Web browser Internet Explorer v[8..11]

Steps to reproduce:

1. Create some public pages with some content (Hello World portlet, for example)

In Liferay 7:

1. Go to Publish -> Export -> Add custom export
2. In Content select "Choose Content"
3. Check "Date Range"
4. Choose a correct Start Date and End Date (that is, both previous to today and start previous to end)
5. Click on Refresh Counts

In Liferay 6.2:

1. Go to Admin -> Pages -> Export
2. In Content check "Choose Content"
3. In "Date Range" click on "Change"
4. In "Date Range" modal window check "Date Range"
5. Choose a correct Start Date and End Date (that is, both previous to today and start previous to end)
6. Click on "OK" button

Expected behaviour:
The content to be exported is refreshed.

Actual behaviour:
An error notice is displayed: "Selected dates cannot be in the future"
