Hi,
I have an attribute whose type i have specified as an ecore:ref to a
another element present in the xsd. The declartion looks like this
<xsd:attribute ecore:reference="ElementType" name="attrFile">
<xsd:simpleType>
<xsd:list itemType="xsd:anyURI"/>
</xsd:simpleType>
A button comes when we click on this attribute value in propertysheet view
after i run this eclipse application. On clicking of this button a Dialog
is opened which is created in FeatureEditorDialog.class.
Instead of the dialog created by FeatureEditorDialog i want to display my
own custom dialog when the user clicks on this button.
Since FeatureEditorDialog is a .class file so i cannot modify it.
The another option is to catch hold of this button listener but i am
unable to find that.
Can some one help me on resolving this issue.
Thanks in advance
Rahul

Rahul,
The setPropertyValue method does this:
public void setPropertyValue(Object object, Object value)
{
EObject eObject = (EObject)object;
EditingDomain editingDomain = getEditingDomain(object);
if (parentReferences != null)
{
Command removeCommand = null;
for (int i = 0; i < parentReferences.length; ++i)
{
Object oldValue = eObject.eGet(parentReferences[i]);
if (oldValue != null)
{
final EReference parentReference = parentReferences[i];
if (oldValue == value)
{
return;
}
else if (parentReference.getEType().isInstance(value))
{
if (editingDomain == null)
{
eObject.eSet(parentReference, value);
}
else
{
editingDomain.getCommandStack().execute(SetCommand.create(ed itingDomain,
getCommandOwner(eObject), parentReference, value));
}
return;
}
else
{
if (editingDomain == null)
{
eObject.eSet(parentReference, null);
}
else
{
removeCommand = SetCommand.create(editingDomain,
getCommandOwner(eObject), parentReference, null);
}
break;
}
}
}
for (int i = 0; i < parentReferences.length; ++i)
{
final EReference parentReference = parentReferences[i];
if (parentReference.getEType().isInstance(value))
{
if (editingDomain == null)
{
eObject.eSet(parentReferences[i], value);
}
else
{
if (removeCommand != null)
{
final CompoundCommand compoundCommand = new
CompoundCommand(CompoundCommand.LAST_COMMAND_ALL);
compoundCommand.append(removeCommand);
compoundCommand.append(SetCommand.create(editingDomain,
getCommandOwner(eObject), parentReference, value));
editingDomain.getCommandStack().execute(compoundCommand);
}
else
{
editingDomain.getCommandStack().execute(SetCommand.create(ed itingDomain,
getCommandOwner(eObject), parentReference, value));
}
}
break;
}
}
}
else
{
if (editingDomain == null)
{
eObject.eSet(feature, value);
}
else
{
editingDomain.getCommandStack().execute(SetCommand.create(ed itingDomain,
getCommandOwner(eObject), feature, value));
}
}
}
I suggested looking at it because that's how the EMF properties view
does all it's updating. I.e., no matter what cell editor is used, it
eventually calls this with the value that the cell editor has
specified. I don't really understand the issue you describe about
getPropertyDescriptor. All I can really do is point you at the
generated code that already works as an example and hope that from that
example you can make the specializations you need to make your case work...
