[Nusoap-general] sending a null

[Barry S. <bar...@br...>]

Hello,
   I am trying to send a null value to a wsdl. A jsp page generates the =
following tag for the parameter :-
      <in5 xsi:type=3D"xsd:string" xsi:nil=3D"true"/>

   The php page generates :-
       <in5 xsi:type=3D"xsd:string"></in5>

This is causing a problem with the web service. How do I format the =
parameter to match the jsp tag. The parameters I am passing using the =
nusoap library is :-

$param =3D array('in0' =3D> 'PERSON', 'in1' =3D> 'PERSONTENPROP', 'in2' =
=3D> '', 'in3' =3D> 'PERSONNUMBER', 'in4' =3D> '33', 'in5' =3D> '');

$details =3D $proxy->call('findSearchResultsByPK', $param);

Can anybody help to reformat the null tags to :-       <in5 =
xsi:type=3D"xsd:string" xsi:nil=3D"true"/>

Thanks for your help
