Thanks Dennis, In this case I don't want the null elements to appear. I have compacted the array before marshalling and it works fine. This isn't a problem because JiBX is not being used for unmarshalling.

If so, you can use nillable="true" to support this. If you *don't* want the null items represented in the XML you need to compact the array ahead of time (or hide it behind an iterator or such - but then you won't get an array when unmarshalling). - Dennis Dennis M.
