I realized that the widget assume just this URL when the page is loaded:
http://<UMP_hostname_or_IP>/usm/jsp/standalone.jsp#
It ignores the parameters I have informed to get the exact view I want.
?user=XYZ&password=blablabla&view=badge1&group=\Group\Subgroup
Does anyone knows if it is a limitation on Widget URL's?
Regards.
