I am getting the error "Current text selection cannot be opened in an editor" when I press F3 on the name of another class in my project. I have only one project open so it is not a duplicate of bug 316573 or bug 430605 and I have no errors in my .log file Both the file I have open and the file I'm trying to access are .java files in the project's src directory and Ctrl-Shift-T finds them without any issue. I am using GWT and the Google Plugin in this project but I'm not sure if that's relevant.
From you description I don't see anything suspicious, so it's hard to guess what's going wrong. Is the problem reproducible across Eclipse sessions? Would you be able to zip the project (or a reduced version still showing the problem) and share it here?
I've tried to reproduce the problem without my product source but I can't seem to. I've found that the problem might be related to classes that extend UIObject from GWT. Do you have any suggestions for how to debug the problem myself? Any logger which might help?
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
Current JDT (2019.6) gives this problem quite often, but without any noticeable logging or exceptions. I can't ctrl-click on the method name, nor F3 to navigate to the method. The method is in the same .java file, the active perspective is Java (also doesn't work in debug perspective) and the .java file is opened in the Java editor. ctrl-o does show the method in the editor

Created attachment 279690 [details] Screen shot demonstrating the clickable/non-clickable identifiers in a Java file In this screenshot I hovered (ctrl mouse movement) over all identifiers. Anything that is green is ctrl-clickable, anything that is red is not. Most are clickable, but the ListItem identifier on line 72 is the first that is not clickable. The type itself is clickable in the import list. Note that the method calls with errors on lines 53-56 are clickable, but the same method calls on lines 76-79 are not. Fully qualifying the method calls (76-79) with ControleResultatenPanel.this.xxx does not help. When I change line 74 from `Path folder = item.getModelObject()` to `Path folder = Path.get("banana");`, the Path identifier is clickable, but the get identifier is not.

Thanks, this _may_ give some hints. Much better, still, would be a zipped project, since we cannot paste a screenshot into a workspace :) One observation from the screenshot: the cursor is on a "red" type reference "ListItem", so I assume it's not navigable. BUT the import for ListItem is highlighted by mark occurrences. So JDT/UI is well aware of the resolved type of this type reference. In case you cannot share a reproducing project, you could try the following: comment or delete lines from the bottom of the method, and watch if and at what point navigation becomes possible. My theory behind this: some syntactic detail of your code lets the SelectionParser create bogus AST. Removing code line by line might point us directly to the culprit.
It appears that the issue [in this Java file, in this project] is caused by the diamond type of the add(new ListView<>(...) call on line 67. When I add the type add(new ListView<Path>(...) { I can click on the ListItem identifier, and all other identifiers. Our cleanup settings instruct Eclipse to remove superfluous types, so the Path type gets removed as it can be inferred.
All other modifications I did by commenting out method definitions and contents did not give any result. Only introducing the type parameter into the diamond of the ListView<> restored the click functionality.
Thanks for narrowing it down. Tentatively scheduling to look into this during the next release cycle.
This code snippet exhibits this issue for Java 11 and my Eclipse 2019.6 installation: package com.mycompany; import java.util.function.Consumer; public class Foo { public Foo() { new Bar<>() { void bar(Consumer<Object> c) { }; }; } } class Bar<T> { void bar(Consumer<T> c) { } }
Even shorter reproduction case: import java.util.function.Consumer; public class Foo { public static void foo(){ new Consumer<> () { @Override public void accept(Object t) { foo(); } }; } } Clicking on the foo() call does not work, unless a token is inside the diamond after new Consumer.
I also got a ton of these exceptions in my error view, when trying to reproduce the issue. I've included the stack trace below. That said: this exception does not typically occur when I can't ctrl-click on an element, so this might be a different state issue unrelated to 473500 --- java.lang.NullPointerException at org.eclipse.jdt.internal.codeassist.SelectionEngine$1Visitor.visit(SelectionEngine.java:1489) at org.eclipse.jdt.internal.compiler.ast.Argument.traverse(Argument.java:238) at org.eclipse.jdt.internal.compiler.ast.MethodDeclaration.traverse(MethodDeclaration.java:355) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.traverse(TypeDeclaration.java:1522) at org.eclipse.jdt.internal.compiler.ast.QualifiedAllocationExpression.traverse(QualifiedAllocationExpression.java:689) at org.eclipse.jdt.internal.compiler.ast.ConstructorDeclaration.traverse(ConstructorDeclaration.java:647) at org.eclipse.jdt.internal.codeassist.SelectionEngine.selectLocalDeclaration(SelectionEngine.java:1516) at org.eclipse.jdt.internal.codeassist.SelectionEngine.select(SelectionEngine.java:1076) at org.eclipse.jdt.internal.core.Openable.codeSelect(Openable.java:168) at org.eclipse.jdt.internal.core.CompilationUnit.codeSelect(CompilationUnit.java:390) at org.eclipse.jdt.internal.core.CompilationUnit.codeSelect(CompilationUnit.java:383) at org.eclipse.jdt.internal.ui.javaeditor.JavaElementHyperlinkDetector.detectHyperlinks(JavaElementHyperlinkDetector.java:116) at org.eclipse.ui.texteditor.HyperlinkDetectorRegistry$HyperlinkDetectorDelegate.detectHyperlinks(HyperlinkDetectorRegistry.java:81) at org.eclipse.jface.text.hyperlink.HyperlinkManager.findHyperlinks(HyperlinkManager.java:289) at org.eclipse.jface.text.hyperlink.HyperlinkManager.findHyperlinks(HyperlinkManager.java:262) at org.eclipse.jface.text.hyperlink.HyperlinkManager.mouseMove(HyperlinkManager.java:457) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:216) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:89) at org.eclipse.swt.widgets.Display.sendEvent(Display.java:4364) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1512) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1535) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1520) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:1324) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:4151) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3768) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$5.run(PartRenderingEngine.java:1173) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:338) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:1062) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:155) at org.eclipse.ui.internal.Workbench.lambda$3(Workbench.java:635) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:338) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:559) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:150) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:155) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:203) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:137) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:107) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:400) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:255) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:567) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:660) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:597) at org.eclipse.equinox.launcher.Main.run(Main.java:1468)

Cannot reproduce with eclipse-SDK-I20211015-1800-win32-x86_64, Java-11 on Windows 10. The problem cases in Comment 11 and Comment 12 seems to work ok. Also tested various link types in JDT without seeing the reported problem. The error log is not reporting any problem.
I can still reproduce it with a more complex code, but am wondering how to make it a reproducible minor case. In the code below I am able to CTRL-click and F3 to all identifiers, except on the first 'item.getModelObject()' (trying to click on the getModelObject(). Any subsequent `item.getModelObejct()` reference is clickable. However when I introduce the type parameter in new ListView<Path>(...), the first item.getModelObject() does become clickable. form.add( new ListView<>("file-row", LoadableDetachableModel.of(this::getContentsOfSourceFolder)) { private static final long serialVersionUID = 1L; @SuppressFBWarnings("NP_NULL_ON_SOME_PATH_FROM_RETURN_VALUE") @Override protected void populateItem(ListItem<Path> item) { var path = item.getModelObject(); var fileUitgepakt = fileUitgepakt(path); item.add(new Label("file-name", path.getFileName().toString())); item.add(new Label("file-time", () -> HumanReadableTime.dateToAgo( Date.from(lastModifiedTime(item.getModelObject()).toInstant())))); item.add(new Label("file-size", () -> getFileSize(item.getModelObject()))); item.add(new Label("check-square").add(AttributeModifier.append("data-feather", fileUitgepakt ? "check-square" : "square"))); item.add(new Label("file-date", getFileUitpakDatum(path))); } });
I've downloaded wicket-9.5.0 and tested with code snippet below and still cannot reproduce...

Can you try with a later build from https://download.eclipse.org/eclipse/downloads/drops4/I20211022-0920/ ? It seems that it might have been fixed after 2021-09. As I wrote in Comment 17 I used eclipse-SDK-I20211015-1800-win32-x86_64 when testing.
Still occurs with Eclipse 2022-03. You can reproduce it as follows: please find attached pom.xml & example Java Program. Create the project & remember to do a "Maven/Update Project". The following errors occur: - F3 over "transformer.transform" -> "Current text selection cannot be opened in an editor" in Status-Bar - MouseOver "transformer.transform" -> "Occurrence of 'transform'" in Popup instead of Javadoc Now delete the Dependencies from the pom: -> F3 & Javadoc OK Please find attached Screenshots of the Project (only 1 in Workspace) & the Error-Messages.
