I have very simple html code (no css, nor js) that includes five inputs with type="radio" (in one column) and webview in JavaFX 8 which loads this page.
The problem is the following - sometimes these radios are rendered sometimes not. For example, I start application - webview loads page, however there is empty space where these radio must be (these inputs are not rendered,they are not seen). But, when I move mouse over the area where these radios must be, they appear. I see this problem in Linux - Centos, Ubuntu and Windows XP. I've not seen this problem in Win7. Here is the code I tested. All the program consists of two classes: public class JavaFXApplication extends Application { private int count=0; @Override public void start(Stage primaryStage) { final Button printButton = new Button("Print"); final WebView webPage = new WebView(); final WebEngine webEngine = webPage.getEngine(); printButton.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent e) { String html="<html dir=\"ltr\"><head>\n" + " <meta http-equiv=\"content-type\" content=\"text/html; charset=utf-8\">\n" + "</head>\n" + "<body contenteditable=\"true\">\n" + " \n" + " \n" + " \n" + "\n" + "\n" + "<p align=\"justify\" style=\"text-align: left; margin-bottom: 0in; line-height: 150%;margin-bottom: 0in; line-height: 100%\">\n" + "<font style=\"font-size: 14pt\" face=\"serif\">Стали бы Вы на пути\n" + "грабителя грузового вагона?</font></p><p align=\"justify\" style=\"text-align: left; margin-bottom: 0in; line-height: 150%;\"><font style=\"font-size: 14pt\" face=\"serif\">Выберите ответ:</font></p>\n" + "\n" + "<form name='mainForm' style='margin-top:15px;'>\n" + "<input type='radio' name='answer' value='641' ><font size='4'>Полностью согласен, полное «Да»</font><br>\n" + "<input type='radio' name='answer' value='642' ><font size='4'>Больше «Да», чем «Нет»</font><br>\n" + "<input type='radio' name='answer' value='643' ><font size='4'>Ни «Да», ни «Нет», нечто среднее</font><br>\n" + "<input type='radio' name='answer' value='644' ><font size='4'>Больше «Нет», чем «Да»</font><br>\n" + "<input type='radio' name='answer' value='645' ><font size='4'>Полное «Нет»</font><br>\n" + "</form><script type=\"text/javascript\">\n" + "function getAnswerId(){\n" + " var elements = document.getElementsByName(\"answer\");\n" + " for (var i=0, len=elements.length; i<len; ++i) {\n" + " if (elements[i].checked) return elements[i].value;\n" + " }\n" + " return null;\n" + "}\n" + "</script></body></html>"; html+=count; count++; webEngine.loadContent(html); } }); HBox hbox = new HBox(); hbox.getChildren().addAll(printButton); BorderPane borderPane = new BorderPane(); borderPane.setTop(hbox); borderPane.setCenter(webPage); Scene scene = new Scene(borderPane, 300, 250); primaryStage.setTitle("WebView radio bugs"); primaryStage.setScene(scene); primaryStage.show(); } } And the second class public class JavaApplication { /** * @param args the command line arguments */ public static void main(String[] args) { Application.launch(JavaFXApplication.class, args); } } After that I click Print button. After every clicking count++. Compiled openjdk 1.8.45. Tested winxp oracle 1.8.40, centos71,ubuntu 12 oracle 1.8.60. The image from xp. 29 clicks after that no radios. Moved mouse over 1,3,5: . The result is on the image I attached. Please, answer. -- Александр Свиридов
