In an Xbase language, when you refactor an element inferred to a static method, existing references are replaced with the fully qualified name of the renamed element. This happens in Xtend as well. For example, given this Xtend program package mypackage class MyXtendFile { def static void foo() { foo() } } select "foo", start refactoring, e.g, as "bar" and press ENTER; after refactoring the modified program is package mypackage class MyXtendFile { def static void bar() { mypackage.MyXtendFile.bar() } }
Some additional comments (see also https://www.eclipse.org/forums/index.php/t/943988/): I tried to debug a little bit what is going on during refactoring; I don't know whether this can help, but I found suspicious what happens in this method RefactoringScopeReferenceSerializer public String getCrossRefText(EObject owner, CrossReference crossref, EObject target, RefTextEvaluator refTextEvaluator, ITextRegion linkTextRegion, StatusWrapper status) { try { final EReference ref = GrammarUtil.getReference(crossref, owner.eClass()); final IScope scope = scopeProvider.getScope(owner, ref); ... Iterable<IEObjectDescription> descriptionsForCrossRef = scope.getElements(target); String bestRefText = null; for (IEObjectDescription desc : descriptionsForCrossRef) { try { String unconvertedRefText = qualifiedNameConverter.toString(desc.getName()); String convertedRefText = valueConverter.toString(unconvertedRefText, ruleName); if (refTextEvaluator.isValid(desc) && (bestRefText == null || refTextEvaluator.isBetterThan(convertedRefText, bestRefText))) bestRefText = convertedRefText; the call to refTextEvaluator.isValid(desc) returns false; this happens because return new RefTextEvaluator() { public boolean isValid(IEObjectDescription newTarget) { IScope scope = linkingScopeProvider.getScope(referringElement, reference); IEObjectDescription element = scope.getSingleElement(newTarget.getName()); // TODO here we need to simulate linking with the new name instead of the old name if(element instanceof IIdentifiableElementDescription) { IIdentifiableElementDescription casted = (IIdentifiableElementDescription) element; if(!casted.isVisible() || !casted.isValidStaticState()) return false; } casted.isValidStaticState() returns false since its implicitReceiverType is NOT null (it is the inferred Java class).
