Web service model initialization problem

Question

Hello, every one
I have some trouble in the initialization of web service model.
I tested the web service through web service navigator and it was ok.
My context structure is:
Request_ZBAPIWCALIST_zbapiWcalist(0..n)
--parameters(0..1)
rBdate(0..n)
high(string)
low(string)
option(string)
sign(string)
--Response(0..1)
Result(0..1)
tWca(0..n)
estat(string)
istat(string)
Following is my codes:
Request_ZBAPIWCALIST_zbapiWcalist model = new Request_ZBAPIWCALIST_zbapiWcalist();
ComplexType_ZbapiWcalist parameter = new ComplexType_ZbapiWcalist();
model.setParameters(parameter);          
ComplexType_ZbapiRBdate rBdate = new ComplexType_ZbapiRBdate();
ComplexType_ZbapiRResp rResp = new ComplexType_ZbapiRResp();
ComplexType_ZbapiRTplnr rTplnr = new ComplexType_ZbapiRTplnr();
ComplexType_ZbapiRWapinr rWapinr = new ComplexType_ZbapiRWapinr();
ComplexType_ZbapiRWapius rWapius = new ComplexType_ZbapiRWapius();
ComplexType_ZbapiWcalistImport wcaImport = new ComplexType_ZbapiWcalistImport();
rBdate.setLow("2007-7-1");
rBdate.setHigh("2007-7-2");
rBdate.setOption("EQ");
rBdate.setSign("I");          
rResp.setLow("");
rResp.setHigh("");
rResp.setOption("");
rResp.setSign("");
rTplnr.setLow("");
rTplnr.setHigh("");
rTplnr.setOption("");
rTplnr.setSign("");
rWapinr.setLow("");
rWapinr.setHigh("");
rWapinr.setOption("");
rWapinr.setSign("");
rWapius.setLow("");
rWapius.setHigh("");
rWapius.setOption("");
rWapius.setSign("");
wcaImport.setAnye("");
wcaImport.setAnyi("");
wcaImport.setSpd("");
wcaImport.setStatu("");
wcaImport.setWerks("");          
ZbapiRBdate rBdateBean = rBdate.getOriginalBean();
ZbapiRResp rRespBean = rResp.getOriginalBean();
ZbapiRTplnr rTplnrBean = rTplnr.getOriginalBean();
ZbapiRWapinr rWapinrBean = rWapinr.getOriginalBean();
ZbapiRWapius rWapiusBean = rWapius.getOriginalBean();
ZbapiWcalistImport wcaImportBean = wcaImport.getOriginalBean();
ZbapiRBdate[] rBdateArray = new ZbapiRBdate[1];
rBdateArray[0] = rBdateBean;
ZbapiRResp[] rRespArray = new ZbapiRResp[1];
rRespArray[0] = rRespBean;
ZbapiRTplnr[] rTplnrArray = new ZbapiRTplnr[1];
rTplnrArray[0] = rTplnrBean;          
ZbapiRWapinr[] rWapinrArray = new ZbapiRWapinr[1];
rWapinrArray[0] = rWapinrBean;          
ZbapiRWapius[] rWapiusArray = new ZbapiRWapius[1];
rWapiusArray[0] = rWapiusBean;
wcalistBean.setRBdate(rBdateArray);
wcalistBean.setRResp(rRespArray);
wcalistBean.setRTplnr(rTplnrArray);
wcalistBean.setRWapinr(rWapinrArray);
wcalistBean.setRWapius(rWapiusArray);
wcalistBean.setWaImport(wcaImportBean);
wdContext.nodeRequest_ZBAPIWCALIST_zbapiWcalist().bind(model);
The exception is:
LocalizedMessage: Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.XmlMarshalException: XML Serialization Error. Property [Low] of class [com.pjs.wcalist.model.wsmodel.proxies.types.p1.ZbapiRWapius] must exist and can not be null. This is required by schema description.
In the test of the web service the Low of the ZbapiRWapius is not needed.
And after setting the value, the exception told me that I must set the tWca, ie the subnode of the result.
The problem is: I do not know why the setter method of the original bean of the "parameters" only accept the parameter of array type .
I think the parameter I set may be wrong.
When I deal with another web service model(the level of the structure is not deep), it is ok.
Could someone give me some suggestion or explanation?
Thanks a lot.
