DataSourceField with Long type is displayed incorrectly

[dejan]

I have strange situation when using big long values. I use JPA data source with following ds.xml file:

<!-- <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %> -->
  
<DataSource xmlns:fmt="urn:jsptld:http://java.sun.com/jsp/jstl/fmt" 
    ID="client"  
    serverConstructor="com.isomorphic.jpa.JPA2DataSource"  
    autoDeriveSchema="true"  
    schemaBean="net.esteh.esdoc.domain.Client">  
    
    <fields>
        <field name="id"  title="ID" primaryKey="true" type="integer"/>
        <filed name="name" type="text" />
    	<filed name="address" type="text" />
    	<field name="city" type="city" />
    	...
    </fields>
    
        
</DataSource>

Java class is simple:

  @Id
    @Column(name="id")
    private Long id;
    
    @Column(name="name", columnDefinition="nvarchar(255)")
    private String name;
    
    @Column(name="address")
    private String address;
    
    @Column(name="city")
    private String city;
    
   ...

As you can see I am using integer type in DataSource for mapping Long java type (as suggested in docs/forum).


I have simple ListGrid which displays values from this DataSource. However, when displaying large values in ID column I am getting strage results, like some kind of rounding happens behind the scene. For example for record with ID=170005001048600028 list grid displays 170005001048600030 or 105000000000110990 instead of 105000000000110997. It seems that last two digits are always displayed incorrectly.

What is the problem here? I am using SmartGWT Power 3.0p (few weeks old build)
