minoccurs=0; nillable="true not interpreted in Web Services
In one of the previous posts I've defined a workaround concerning the nillable attribute being ignored when invoking web services using xsd's defined in the following manner.Because in bpel you're not able to define the xsi:nil-attribute at design time, you need to define this manually.The xsi:nil=true-attribute is the solution to tell web services that this attribute, if empty, needs to be ignored. In this way serialization and deserialization will work, otherwise you will always run into NullPointerException.What's the cause of our problem when talking about bpel [metalink Note:403586.1]:The XSLT transformer used by BPEL was not originally designed to pass xsi:nil
