Due to the modification of the number of anchors in the selection listener, the second event refers to a non-existing anchor in this scenario. The fix was to guard the array access. An interesting observation is that it does not happen in IE. FF issues two selection events for a double click, IE only one. Opened bug 252559 for this issue. Also fixed in SR 1.1.2. |
Consider a Link control with a registered SelectionListener. Within the widgetSelected(SelectionEvent) method, change the text of the Link control where the selection listener applies to: ... public void widgetSelected(SelectionEvent arg0) { link.setText("Lorem ipsum dolor sit amet"); // without any <a> } ... In our case, the new text now doesn't contain an anchor tag (<a>) and therefore is not longer a real link. Now, double clicking on that link results in an HTTP 500 error with the following stack trace: java.lang.ArrayIndexOutOfBoundsException: 0 org.eclipse.swt.internal.widgets.linkkit.LinkLCA.getIdText(LinkLCA.java:126) org.eclipse.swt.internal.widgets.linkkit.LinkLCA.readData(LinkLCA.java:65) org.eclipse.swt.internal.widgets.displaykit.DisplayLCA$1.doVisit(DisplayLCA.java:259) org.eclipse.swt.internal.widgets.WidgetTreeVisitor$AllWidgetTreeVisitor.visit(WidgetTreeVisitor.java:28) org.eclipse.swt.internal.widgets.WidgetTreeVisitor.accept(WidgetTreeVisitor.java:59) org.eclipse.swt.internal.widgets.WidgetTreeVisitor.accept(WidgetTreeVisitor.java:51) org.eclipse.swt.internal.widgets.WidgetTreeVisitor.accept(WidgetTreeVisitor.java:51) org.eclipse.swt.internal.widgets.WidgetTreeVisitor.accept(WidgetTreeVisitor.java:51) org.eclipse.swt.internal.widgets.displaykit.DisplayLCA.readData(DisplayLCA.java:266) org.eclipse.rwt.internal.lifecycle.ReadData.execute(ReadData.java:26) org.eclipse.rwt.internal.lifecycle.RWTLifeCycle.continueLifeCycle(RWTLifeCycle.java:208) org.eclipse.rwt.internal.lifecycle.RWTLifeCycle.sleep(RWTLifeCycle.java:305) org.eclipse.swt.widgets.Display.sleep(Display.java:703) <ourEntryPoint>.createUI(...) org.eclipse.rwt.internal.lifecycle.EntryPointManager.createUI(EntryPointManager.java:92) org.eclipse.rwt.internal.lifecycle.RWTLifeCycle.createUI(RWTLifeCycle.java:230) org.eclipse.rwt.internal.lifecycle.RWTLifeCycle$UIThreadController.run(RWTLifeCycle.java:116) java.lang.Thread.run(Thread.java:595) We encountered the error using Firefox 2.0 and Google Chrome. Internet Explorer 6 and 7 works fine. Kind regards Andre Weber
