Hi,
I'm trying to remove an object from a CDOResource, but when doing a resource.save() an exception is thrown..
This is the code:
IStructuredSelection sel = (IStructuredSelection) tableViewer.getSelection();
if(sel.getFirstElement() != null){
Person p = (Person) sel.getFirstElement();
personResource.getContents().remove(p);
try {
personResource.save(null);
} catch (IOException e1) {
e1.printStackTrace();
}
}
And this is the exception:
Caused by: java.lang.UnsupportedOperationException
