Changesummary of datagraph using static interfaces.
---------------------------------------------------
Key: TUSCANY-1305
URL: https://issues.apache.org/jira/browse/TUSCANY-1305
Project: Tuscany
Issue Type: Bug
Components: Java SDO Implementation
Affects Versions: Java-SDO-Next
Reporter: Steffen Glomb
I cant get Changesummary on a datagraph working correctly with the following
contents: (hope this is a realy a bug this time)
Schema, generated by the xsdhelper:
<xs:schema
xmlns:sdo="commonj.sdo" xmlns:sdoJava="commonj.sdo/java"
xmlns:stn_1="http://example.com/customer";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
attributeFormDefault="qualified" elementFormDefault="qualified"
targetNamespace="http://example.com/customer";>
<xs:complexType abstract="false" name="Account">
<xs:sequence/>
<xs:attribute default="0" name="accountNum" type="xs:int"/>
</xs:complexType>
<xs:element name="account" type="stn_1:Account"/>
<xs:complexType abstract="false" name="Customer">
<xs:sequence>
<xs:element name="account" type="stn_1:Account"/>
</xs:sequence>
<xs:attribute name="firstName" type="xs:string"/>
</xs:complexType>
<xs:element name="customer" type="stn_1:Customer"/>
</xs:schema>
After generation of interfaces the following code fails to work as I would
expect, because the changesummary does not contain the changed dataobject in
the graph.
....
import org.apache.tuscany.sdo.api.SDOUtil;
import com.example.customer.Account;
import com.example.customer.Customer;
import com.example.customer.CustomerFactory;
import commonj.sdo.DataGraph;
import commonj.sdo.Type;
import commonj.sdo.helper.HelperContext;
import commonj.sdo.impl.HelperProvider;
public class TestChangesummary extends TestCase {
public void testChangeSummaryOnDatagraphWithContainmentStatic() throws
Exception {
HelperContext hc = HelperProvider.getDefaultContext();
CustomerFactory.INSTANCE.register(hc);
Type customerType = hc.getTypeHelper().getType(Customer.class);
DataGraph dataGraph = SDOUtil.createDataGraph();
Customer customer = (Customer)
dataGraph.createRootObject(customerType);
Account account = CustomerFactory.INSTANCE.createAccount();
customer.setAccount(account);
customer.setFirstName("John");
customer.getAccount().setAccountNum(1234);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
SDOUtil.saveDataGraph(dataGraph, outputStream, null);
DataGraph loadDataGraph = SDOUtil.loadDataGraph(new
ByteArrayInputStream(outputStream.toByteArray()), null);
loadDataGraph.getChangeSummary().beginLogging();
customer = (Customer) loadDataGraph.getRootObject();
customer.getAccount().setAccountNum(987);
loadDataGraph.getChangeSummary().endLogging();
List changedDataObjects =
loadDataGraph.getChangeSummary().getChangedDataObjects();
assertEquals("in fact 1 Object was changed in the code", 1,
changedDataObjects.size());
}
}
