Problem using SimpleAnyType [message #425532] Mon, 01 December 2008 05:30 Go to next message

I've modified my workflow editor to allow the creation of a
SimpleAnyType, and I've run into a problem re-loading the model after
specifying the Instance Type and Value attributes. See the exception
trace below. I'm setting (using the properties editor) Instance Type
to EString, and Value to Hello. I'm leaving the other attributes
blank. Do I need to do anything with the Any or Any Attribute
attributes?

This exception occurs when I try to bring up the model in the editor
and it has a SimpleAnyType with Instance Type and Value set as
described above.

Bryan,

Are you using an extended metadata option?

public EClassifier getType(EFactory eFactory, String typeName)
{
if (eFactory != null)
{
EPackage ePackage = eFactory.getEPackage();
if (extendedMetaData != null)
{
return extendedMetaData.getType(ePackage, typeName);
}
else
{
EClass eClass = (EClass)ePackage.getEClassifier(typeName);
if (eClass == null && xmlMap != null)
{
return xmlMap.getClassifier(ePackage.getNsURI(), typeName);
}
return eClass;
}
}
return null;
}

The cast to EClass seems kind of pointless here, but later where the is
used, the extended metadata issues arises again.

public EObject createObject(EFactory eFactory, EClassifier type)
{
EObject newObject = null;
if (eFactory != null)
{
if (extendedMetaData != null)
{
if (type == null)
{
return null;
}
else if (type instanceof EClass)
{
newObject = eFactory.create((EClass)type);
}
else
{
SimpleAnyType result =
(SimpleAnyType)EcoreUtil.create(anySimpleType);
result.setInstanceType((EDataType)type);
newObject = result;
}
}
else
{
if (type != null)
{
newObject = eFactory.create((EClass)type);
}
}
}
return newObject;
}

Ed,

I'm not sure what the extended metadata option is, so let's assume for
now the answer is: no, I'm not using the extended metadata option. I
think I might have found the problem ... when I set the value of the
parameter map entry, the model is serialized as follows:

<?xml version="1.0" encoding="UTF-8"?>
<org.eclipse.emf.workflow.runtime:WorkflowContext xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
xmlns:org.eclipse.emf.workflow.runtime="http://www.eclipse.org/emf/workflow/runtime.ecore">


<parameters>
<value xsi:type="ecore:EString">
Hello <instanceType
href="http://www.eclipse.org/emf/2002/Ecore#//EString"/>
</value>
</parameters>
</org.eclipse.emf.workflow.runtime:WorkflowContext>

It seems that SimpleAnyType is not being serialized correctly. Why is
the value type EString? Shouldn't it be SimpleAnyType? Does this look
incorrect to you? Since I've never used SimpleAnyType, I'm not sure
what to expect when it gets serialized.

/**
* This option allows you to tailor the XML serialization of objects.
* You should provide an ExtendedMetaData as the value of this option.
* @see org.eclipse.emf.ecore.util.BasicExtendedMetaData
*/
String OPTION_EXTENDED_META_DATA = "EXTENDED_META_DATA";

You can provide Boolean.TRUE as well to let it create the right instance
and you need that for both load and save.

Yes, that's no good.

It's supposed to serialize like <value
xsi:type="ecore:EString">Hello</value>
> Shouldn't it be SimpleAnyType?
No, that part's "implicit". I.e., when the xsi:type refers to an
EClassifier that is an EDataType, and instance of SimpleAnyType will be
created.

No, you'll need to use the extended meta data option as a load and a
save option.
