NumberFormatException: For input string: "" in XsTypeConverter

My webservice request contains a tag for an integer field. When this tag is populated with an integer or when I don't include this tag in the request, the web services works fine but when I send an empty tag for this integer field, I get this NubmerFromatException in weblogic when it constructs soap request (stack trace below)

Soap Request :
<caseSearching>
<CaseSearchInput>
<m1:AerNum>981209-107024933</m1:AerNum>
<m1:AgeCodeId />
<m1:CurrentVersion>true</m1:CurrentVersion>
<m1:NotAerNum>false</m1:NotAerNum>
</CaseSearchInput>
</caseSearching>


wsdl defenition for this field :
<xs:element minOccurs="1" name="AgeCodeId" nillable="true" type="xs:int" />

It doens't seem to be a problem with minOccurs="1". The issue occurs even when minOccurs="0".

Resopnse with exceptions :
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header />
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server</faultcode>
