Hello,
Updating the CMDBuild's version to 2.1.2, I do not know if it there's a bug in the relation graph, some data are not displayed (while on CMDbuild 2.0.4 all data and relations card was displayed well on the relation graph)
Regards
In the 2.1.2 version there is a bug in the display of the relations graph.
This Friday (June 21) we will release the minor version 2.1.3 which fixes some bugs (including this one) and introduces a couple of new features.
