------------------------------------
Affects Version/s: (was: Java-SDO-beta1)
Java-SDO-M2
> Sequence.add(index,value) is not working due to a type mismatch problem

> Key: TUSCANY-1216
> URL: https://issues.apache.org/jira/browse/TUSCANY-1216
> Project: Tuscany
> Issue Type: Bug
> Components: Java SDO Implementation
> Affects Versions: Java-SDO-M2
> Environment: n/a
> Reporter: David T. Adcox
> Fix For: Java-SDO-beta1
>
>
> The sample below demonstrates a problem found when adding properties into a
> sequence object using the property index. The issue seems to be related to
> how the property index is acquired and how that index is subsequently used by
> the BasicSequence object. BasicSequence.add(int, Object) uses the EMF
> eClass().getEstructuralFeature(int) method to retrieve the property, based on
> the index. The list of properties kept in this array, includes both
> 'explicit' properties defined by the schema or inline code, and 'implicit'
> properties defined by the Tuscany SDO framework (in this case, I believe it
> is actually the underlying EMF that is creating the implicit property). Once
> such implicit property is the 'multi' property, defined when a type is
> identified as containing a sequence. The core issue here is that the code
> used to identify the index to use is based on an array of SDO properties,
> which do not include the implicit properties. So, the index is derived from
> a different array than the one being used for updating, this is the root
> cause of this problem. A change to how the BasicSequence object obtains the
> indexed property is probably the correct remedy for this issue.
> Sample code:
> public static void main(String[] args)
> {
> String URI = "http://example.com/test";;
>
> HelperContext scope = SDOUtil.createHelperContext();
> TypeHelper typeHelper = scope.getTypeHelper();
> Type integerType = typeHelper.getType("commonj.sdo", "Integer");
>
> DataObject wrapperType = scope.getDataFactory().create("commonj.sdo",
> "Type");
> wrapperType.set("uri", URI );
> wrapperType.set("name", "Wrapper");
> wrapperType.setBoolean("sequenced", true);
>
> // Create Property
> DataObject intProperty = wrapperType.createDataObject("property");
> intProperty.set("name", "Value");
> intProperty.set("type", integerType);
> intProperty.setBoolean("many", true);
>
> // register the wrapper
> typeHelper.define(wrapperType);
>
> // get registered type
> Type testType = typeHelper.getType(URI,"Wrapper");
>
> // Create an instance of the Wrapper Type
> DataObject testDO = scope.getDataFactory().create(testType);
> // Update the sequence using the index
> List properties = testType.getProperties();
> int index = properties.indexOf(testDO.getInstanceProperty("Value"));
> Sequence sequence = testDO.getSequence();
> Integer v = new Integer(10);
> sequence.add(index,v);
> }
