How can NULL values be handled for numeric types through XML please? In the below example I get an error but when I enter 0 as the numeric value in the XML it works.
But as you know 0 != NULL

Thanks a lot,
Patrick

XSD

Code: Select all

<?xml version="1.0"?><xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="shotgun">
<xs:complexType>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element name="version">
<xs:complexType><xs:sequence>
<xs:element name="id" type="xs:integer" />
<xs:element name="frame_count" type="xs:integer" minOccurs="0" />
<xs:element name="sg_frames_aspect_ratio" type="xs:decimal" minOccurs="0" />
</xs:sequence></xs:complexType></xs:element>
</xs:choice></xs:complexType></xs:element>
</xs:schema>

XML

Code: Select all

<?xml version="1.0"?>
<shotgun>
  <version>
    <id>3743</id>
    <frame_count></frame_count>
    <sg_frames_aspect_ratio></sg_frames_aspect_ratio>
  </version>
</shotgun>

Hello.

There is no Stimulsoft methods in the error stack. It's a .Net framework error.
Your type is not nullable so you get this error.

Thank you.

If anybody else has the same problem.
http://msdn.microsoft.com/en-us/library/ybce7f69
<xsd:element name="key" type="xsd:string" nillable="true" />
<key xsi:nil="true"/>

Hello.

In your first message the nillable attribute wasn't set to true. So did you solve your problem now?

Thank you.

Hi,

I have the same issue. But here I just create a XML datasource and table inside mrt and pass xml to show data,
Where i put the nillable="true" in mrt file???

Please find the attachement.
I attach a xsd file for Issue, But actualy I dont have it directly in mrt.

Thanks
