Since version 3.0 bookmarks (dogear) module of Connections can be configured to open bookmarks in a new window, but the configuration does not include bookmarks in the Community module.
To get this function consistent and it would be good, when IBM adds the dogear configure switch to communities too.
Until this, you can follow this:
Go to [AppServer-Root]/profiles/[Communities-WAS]/installedApps/[cellname]/Communities.ear/comm.web.war/WEB-INF/tags
Edit displaybookmark.tag and change following line:
<a id="b_uri_${bookmark.uuid}" href="<tango:safeURL>${bookmark.uri}">
to
<div id="b_entry_${bookmark.uuid}">
<h4>
<a target="_blank" id="b_uri_${bookmark.uuid}" href="<tango:safeURL>${bookmark.uri}>
</a>
</h4>
</div>
To recompile the jsps and activate this changes, edit and save the bookmarks.jsp.
Windows
Edit and save following files:
[AppServer-Root]\profiles\[Communities-WAS]\installedApps\[cellname]\Communities.ear\comm.web.war\WEB-INF\jsps\html\scenes\dashboard\sidebarRight.jsp
[AppServer-Root]\profiles\[Communities-WAS]\installedApps\[cellname]\Communities.ear\comm.web.war\WEB-INF\jsps\html\scenes\bookmarks.jsp
Linux:
touch these files:
[AppServer-Root]/profiles/[Communities-WAS]/installedApps/[cellname]/Communities.ear/comm.web.war/WEB-INF/jsps/html/scenes/dashboard/sidebarRight.jsp
[AppServer-Root]/profiles/[Communities-WAS]/installedApps/[cellname]/Communities.ear/comm.web.war/WEB-INF/jsps/html/scenes/bookmarks.jsp
I haven’t found a way to change opening links in new window in the rightsidebar “Important Bookmarks” and in Bookmarks Widget of the Community Overview. I think these links are generated through Javascript and Feedreader.
