Comment #1 on issue 992 by anne.et...@gmail.com: FMNullMultivalueLink does not support union: (FMNullMultivalueLink cannot have variable sized instances) http://code.google.com/p/moose-technology/issues/detail?id=992
By adding back FMNullMultiValueLink>>species ^OrderedCollection
it works and all the tests are green. In fact I previously removed this method at the beginning of September. But I found today a case where it is useful so I put it again.
If you agree with this change, the issue can be closed.
