We have an JavaEE web application that provides facility to export to
excel.

Problem:
When we export a report to excel it opens in a new browser window and
everything is fine. But if we try to generate a new excel report
without closing the earlier window(containing the excel report) a new
browser window gets generated, however the excel that was created
earlier moves into this new window and we don't get the latest one
that we requested for. Also the window that contained the preveious
excel report now becomes blank..

Has anyone faced this issue before?
