DSpace Cris Network Lab error

[Lucas Rodrigues Costa]

Sometimes I have a system error when I click in "Network Lab", the relationship chart doesn't appear. This is only occur for some researchers. If I recreate a researcher I fiz the problem. How do I fix this problem without having to re-create the researcher?
