[Spce-user] invoice

[fry]

hi all,

i'm still struggling with the invoice-module. i got following error when
creating a new invoice for last month.. actual month is okey..

Apr  7 21:17:23 sip /usr/share/ngcp-panel/ngcp_panel_fastcgi.pl:
Rechnung erstellen Fehlgeschlagen (DBIx::Class::Schema::txn_do(): Use of
uninitialized value $contract_id in concatenation (.) or string at
/usr/share/perl5/NGCP/Panel/Controller/Invoice.pm line 163. at
/usr/share/perl5/Catalyst/Model/DBIC/Schema.pm line 501#012)

any idea?
