Browser/CURL requests to WS w/response extending a type

I've written a web service with Axis2 1.6.2 with a request that extends
another type, with a request element that looks like this in its .xsd:

<xsd:element name="requestName">
    <xsd:complexType>
        <xsd:complexContent>
            <xsd:extension base="requestBaseType">
                <xsd:sequence>
                    <xsd:element name="param1" type="xsd:int" minOccurs="1"
maxOccurs="1" />
                    <xsd:element name="param2" type="xsd:string"
minOccurs="1" maxOccurs="1" />
                    <xsd:element name="param3" type="xsd:int" minOccurs="0"
maxOccurs="1" />
                </xsd:sequence>
            </xsd:extension>
        </xsd:complexContent>
    </xsd:complexType>
</xsd:element>

<xsd:complexType name="requestBaseType">
    <xsd:sequence>
        <xsd:element name="baseTypeParam1" type="xsd:string" minOccurs="0"
maxOccurs="1" />
    </xsd:sequence>
</xsd:complexType>

Sending requests to this web service works just fine if I send the requests
from SoapUI or similar, but if I send the same request via GET from a
browser I get this error:

<faultstring>org.apache.axis2.databinding.ADBException: Unexpected
subelement {http://campusm.gw.com/campusm}requestName</faultstring>

It's saying there's an unexpected element of a type that is the correct
request type, even though in a GET request that request object is implicit.

If I stop it extending requestBaseType, it works fine in both the browser
and SoapUI. Here's the xsd definition that fixes the problem:

<xsd:element name="requestName">
    <xsd:complexType>
        <xsd:sequence>
            <xsd:element name="baseTypeParam1" type="xsd:string"
minOccurs="0" maxOccurs="1" />
            <xsd:element name="param1" type="xsd:int" minOccurs="1"
maxOccurs="1" />
            <xsd:element name="param2" type="xsd:string" minOccurs="1"
maxOccurs="1" />
            <xsd:element name="param3" type="xsd:int" minOccurs="0"
maxOccurs="1" />
        </xsd:sequence>
    </xsd:complexType>
</xsd:element>

Here's an example of the GET request I send in the browser that gets this
error:

http://localhost:8080/path/to/webservice?baseTypeParam1=stuff&param1=12&param2=thing&param3=13

Here's an example of the request I send from SoapUI that works:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:cam="http://campusm.gw.com/campusm">
   <soapenv:Header/>
   <soapenv:Body>
      <cam:requestName>
         <cam:baseTypeParam1>stuff</cam:baseTypeParam1>
         <cam:param1>12</cam:param1>
         <cam:param2>thing</cam:param2>
         <cam:param3>13</cam:param3>
      </cam:requestName>
   </soapenv:Body>
</soapenv:Envelope>

I need the request to extend a type so that I can have multiple web
services sending a large common subset of their request parameters to the
same function in my Java code. This would allow the function to take a
parameter of the base request type, and have each web service just pass its
request into that function without any conversion or worring about the
individual parameters at that point.

I also need to be able to call the web services with CURL, which is not
possible if the web services won't work with a GET request.

This seems to be a bug with Axis2. Is this a known issue and will it be
fixed?

Best regards,
Mike
