thanks for the info.
The reason for getDeletedModelElement returning null during an undo of a
reversed create (that is, a delete) is a current limitation of our API,
since we always clear our internal deleted element caches when a delete
operation has been applied, which causes the getDeletedModelElement to
find nothing. Please file a bug for this issue.
Depending on what you are trying to do with the deleted element, a
possible workaround might be to check if you have a
CreateDeleteOperation in the operationUndone method of your observer.
If it returns true for isDelete() you can obtain the deleted element via
getModelElement(). Note though, that this might not cover all your use
cases, since getModelElement returns a copy of the deleted element.
