Using the Ajax Debug panel I could track the problem down rather
easily. While the actual form components were "clean" I found
out that their surrounding containers, some of which were, too,
updated using Ajax were given fixed markup IDs from within the
Java code, so that I had two of them with the same IDs. Need to
do a 'git blame' on that one :)

Cheers,
