Adding nominees to more then one election
Adding nominees to more then one election leads to errors in the list view. The properties of the second election are not mapped. If you edit the second election, everything is loaded.
If you then open and save the first election without changing anything, new entries in the MM-Table tx_election_domain_model_election are created. Seems like an extbase error or some missing/strange configuration. MM-Configuration is in ext_typoscript_setup.txt.
In this test data set voting-4electors.sql.gz only the first election has nominees assigned. Open the second election and assign a nominee to see the effect.
Similar places where this error could happen are the opposite site of the election-nominee-relation and the electorate-elector-relation and it's opposite site.
