By default, Business Process Portal does not support multi-tab browsing. So, after having logged into the Portal, if you try to login again from another tab in the browser, the first instance of the Portal becomes invalid. This might causes several unexpected issues.
To avoid any such issues, you must enable the multi-tab support for Business Process Portal by adding the following line of code to the bpmportal.conf file at $DLC/oebpm/server/conf/ location:
bpmportal.relogin.or.continue = true
This ensures that whenever you try to open the Business Process Portal, you are directed to any active session of the Portal, if available.
