Xmlbeans errors for empty int tag

Hello all,

I am using xmlbeans 1.0.4 and have a strange issue at hand.
We have an old webservice which was documented in DTD and to use advanced xmlbeans features we decided to write an xsd for it and use it at another place to send/get WS calls. Kindly note the xsd is used only at client side..ie.e where it invokes the WS. The WS is still the old one.
Here is a snippet of teh xsd that is causing the issue -
<xs:complexType name ="itemT">
            <xs:sequence maxOccurs="1">
                        <xs:element name="item_id" type="xs:int" minOccurs="1" maxOccurs="1"/>
                        <xs:element name="file_id" type="xs:int" minOccurs="0" maxOccurs="1"/>
                        .......................................
............</xs:sequence>
</xs:complexType>

Now the 'file_id' field above is not mandatory and may be blank. The way our old WS responds in case there is nor file_id associated with type itemT is as follows.
 <item>
        <item_id>1602</item_id>
        <file_id/>
          ..........................
</item>
SO even if there is no value for file_id it still returns an empty tag.

Now this is of type xs:int I cannot do a null check - Hence in my java code whenever I try to access it
like
item.getFileId() - It always throws an exception stacktrace as follows

org.apache.xmlbeans.impl.values.XmlValueOutOfRangeException
    at org.apache.xmlbeans.impl.values.JavaIntHolder.set_text(JavaIntHolder.java:42)
    at org.apache.xmlbeans.impl.values.XmlObjectBase.update_from_wscanon_text(XmlObjectBase.java:1085)
    at org.apache.xmlbeans.impl.values.XmlObjectBase.check_dated(XmlObjectBase.java:1224)
    at org.apache.xmlbeans.impl.values.JavaIntHolder.intValue(JavaIntHolder.java:52)
    at org.apache.xmlbeans.impl.values.XmlObjectBase.getIntValue(XmlObjectBase.java:1442)
    at com.company.webservices.live.impl.ItemTImpl.getFileId(Unknown Source)
    at com.company.live.ws.service.NewWebService.fetchItem(LiveWebService.java:150)


Is there a way in xmlbeans by which I can check that whether a "int value"   is present or not (like we do for String i.e. null check) and only then try to retrieve the fileId value?

I tried using item.isSetFileId() but that returns as true.

I also tried item.xgetFileId() - checked if that is null but again when we try to get intValue() it throws same exception.

Can anyone kindly help?

Thanks in advance,
SSP
