No error message generated during a read operation

A read operation that requests a nonexisting property returns an empty result.

Read operations such as search or get do not return error messages if:

• the property you requested does not exist or the property name is not valid
• you do not have permission to read the property

Write operations such as create or update do throw exceptions.

Example

Request a get for an nonexisting property:

DataObject root = SDOHelper.createRootDataObject();
DataObject entity = SDOHelper.createEntityDataObject(root, null, DO_PERSON);
entity.createDataObject(DO_IDENTIFIER).set(PROP_UNIQUE_NAME,
"uid=SalesManager,cn=users,dc=yourco,dc=com");
DataObject propCtrl = SDOHelper.createControlDataObject(root, null, DO_PROPERTY_CONTROL);
propCtrl.getList(PROP_PROPERTIES).add("sn");
propCtrl.getList(PROP_PROPERTIES).add("uid");
propCtrl.getList(PROP_PROPERTIES).add("cn");
propCtrl.getList(PROP_PROPERTIES).add("NOPROP");
root = service.get(root);

For this particular example the sample input data graph is:

<?xml version="1.0" encoding="UTF-8"?>

<sdo:datagraph xmlns:xsi="//www.w3.org/2001/XMLSchema-instance"
 xmlns:sdo="commonj.sdo"
 xmlns:wim="//www.ibm.com/websphere/wim">

<wim:Root>

<wim:entities xsi:type="wim:PersonAccount">

<wim:identifier uniqueName="uid=SalesManager,cn=users,dc=yourco,dc=com"/>

</wim:entities>

<wim:controls xsi:type="wim:PropertyControl">

<wim:properties>sn
</wim:properties>

<wim:properties>uid
</wim:properties>

<wim:properties>cn
</wim:properties>

<wim:properties>NOPROP
</wim:properties>

</wim:controls>

</wim:Root>

</sdo:datagraph> 

The resulting output data graph is:

<sdo:datagraph xmlns:xsi="//www.w3.org/2001/XMLSchema-instance"
               xmlns:sdo="commonj.sdo"
               xmlns:wim="//www.ibm.com/websphere/wim">

<wim:Root>

<wim:entities xsi:type="wim:PersonAccount">

<wim:identifier externalName="uid=SalesManager,cn=users,dc=yourco,dc=com"
                     repositoryId="LDAP1"
                     uniqueId="5e846c20-a1b4-4bfc-bce2-1f841d762f9a"
                     uniqueName="uid=SalesManager,cn=users,dc=yourco,dc=com"/>

<wim:uid>SalesManager
</wim:uid>

<wim:cn>Sales Manager </wim:cn>

<wim:sn>SalesMgrSn
</wim:sn>

</wim:entities>
</wim:Root>

</sdo:datagraph> 

The requested property NOPROP is not returned nor is an error message generated.
