[xwiki-users] Diagram application - 5.0.1 xwiki

Hi, I tried to install the Diagram Application in a fresh install of xwiki Enterprise 5.0.1 ( http://extensions.xwiki.org/xwiki/bin/view/Extension/Diagram+Application). I'm able to see the diagram viewer/editor from the Diagram Space but unable to display anything in a wiki page and the "save" options from menu are shown greyed (I use the save option from wiki page). I have tried to display the diagram using the Display Macro without any luck (no render). In place, I can only see diagram code in wiki page i.e: <root><mxCell id="0"/><mxCell id="1" parent="0"/><mxCell id="2" value="" style="ellipse" vertex="1" parent="1"><mxGeometry x="410" y="240" width="80" height="80" as="geometry"/></mxCell><mxCell id="3" value="" style="ellipse" vertex="1" parent="1"><mxGeometry x="330" y="260" width="80" height="80" as="geometry"/></mxCell><mxCell id="4" value="Double&#xa;Rounded Rectangle" style="shape=ext;double=1;rounded=1" vertex="1" parent="1"><mxGeometry x="240" y="290" width="120" height="60" as="geometry"/></mxCell></root> Have anyone tried this application with 5.0.X versions? Thanks in advance!
