Webservice request with multiple parameters. Wrong SOAP XML body

Steps to reproduce:
1. Generate SOAP webservice with method that needs more than 2 parameters
2. Import the by the Data/Services tab
3. Call the method
4. The params are encoded all the the first value

Example:
[service].getTestMethod(param1, param2);

Actual Results:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<SOAP-ENV:Body>
<q1_:GetContractsIn xmlns:q1_="http://schemas.invenso.com/TimeTracker/GetContractsIn">
<q1_:Database>
param1
</q1_:Database>
<q1_:KlantId>
param1
</q1_:KlantId>
</q1_:GetContractsIn>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Expected Results:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<SOAP-ENV:Body>
<q1_:GetContractsIn xmlns:q1_="http://schemas.invenso.com/TimeTracker/GetContractsIn">
<q1_:Database>
param1
</q1_:Database>
<q1_:KlantId>
param2
</q1_:KlantId>
</q1_:GetContractsIn>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Notice the value of tag <q1_:KlantId>
