gephi/trunk — Issue #105: NullPointerException when executing the "Eigenvector Centrality" Statistic
Author: mbastian

Labels: Fix Released, Medium

This happens because there is no Builder for the Eigenvector Centrality Statistic: the class EigenvectorCentralityBuilder is missing (it was not imported in revision 1432).
