I made a mistake in r1527171. When I removed the call to GetInvoiceItemTypes.groovy in InvoiceScreens.xml I did not notice it was also generating the AccountOrganizationAndClass list.
This fixes it by renaming GetInvoiceItemTypes.groovy to GetAccountOrganizationAndClass.groovy and removing the now useless invoiceItemTypes list inside it.
