Hi,
I think this is a JAXB issue.
It does not has enough information in the XML document to determine
which ArrayList to choose from. So it is just picking the first one
declared ArrayList<bcOneValueParameter> and using that (JAXB will
ignore any elements it does not understand).
To distinguish between the different parameter elements an xml:type
attribute will be required in the XML document.
Paul.
