Hello,

I have apex class which calls to webservice, and I want to pass parameter of type Datetime with null value
to .net webservice.
 
how to do it ?
 
TIA

According to the Apex doc, you should not have to use fieldsToNull with Apex.  Have you tried simply setting the value to null?

Does the service WSDL allow for the dateTime to be nilable ?

Hi Simon, guess you pointing in the right direction,

The webservice is an ASP.NET webservice and here is small section of its WSDL from wich the apex class is created

 

- <s:element name="IchlusProtocolUpdate">
- <s:complexType>
- <s:sequence>
  <s:element minOccurs="0" maxOccurs="1" name="opportunityID" type="s:string" />
  <s:element minOccurs="1" maxOccurs="1" name="orderNumber" type="s:double" />
  <s:element minOccurs="1" maxOccurs="1" name="institCode" type="s:int" />
  <s:element minOccurs="1" maxOccurs="1" name="expectedArrivalDate" type="s:dateTime" />
  </s:sequence>
  </s:complexType>
  </s:element>
 
if you check the expectedArrivalDate it seems there is no nillable attribute ,is that what you mean ?
 
if so how can one make this attribute appear ?
 
TIA

Solved : well seems like the answer was simple

In asp.net (im using framework 2)  instead of defining just : DateTime somevar

need to define wiht nullable like this Datetime? somevar and than the WSDL includes the nillable="true"
