For a project, I needed a RSS Feed to get updates an show them in an XPage. I was about to create my own RSS Feed custom control, but before that I found this RSS Feed Custom Control from Ulrich Krause.

It's a pretty simple and useful open source custom control, based in the Dojo dojox.widget.PortletFeedSettings widget.

Just one thing to take into account. Ta make it fit in a OneUI design, just add the styleClass attribute with the lotusWidget2 value to the Panel control:

"dojox.widget.ExpandableFeedPortlet"
                style="width:#{javascript:return compositeData.prop_width}px" styleClass="lotusWidget2">
