Re: [castor-dev] Force an element to be marshalled

I don't think the legacy system at the other end can handle elements like that. I actually solved the problem by forcing the value of the CostCenter field to be not-null in the Java Object. If you try to set the field to null, it uses "" instead: 

    protected String costCenter = "";

    public void setCostCenter(String newValue) {
        costCenter = (newValue == null) ? "" : newValue;
    }

Hi August,

if the following is an option to you, yes there is ....

<LineItem>
   <ItemNumber>124029</ItemNumber>
   <ItemQty>1</ItemQty>
   <CostCenter xsi:nil=true" />
</LineItem>
