为了在JavaFX 11中创建Jasper报表,我正在使用dynamic reports。我将报表加载到Swing Node内,但是只有当我单击堆栈窗格区域时,Jasper报表才会出现,并且只有当我悬停在所有这些组件上时,所有其他组件才可见。与其它内容一样,组件和报表内容并非立即加载,而是在鼠标悬停时显示,当滚动堆栈窗格时,报表才会显示。
由于这是Java 8中的错误(bug),似乎已得到解决,但在Java 11中,我仍然遇到相同的问题。
更新
由于我没有得到任何回应,并且像kleopatra建议的那样,我已创建了最小可重现代码。请查看此代码。

运行程序,但无法重现问题。它直接显示完整的内容。尽管我收到了一个警告:“使用 JavaFX API 版本 11.0.1 加载 FXML 文档,JavaFX 运行时版本为 10.0.2-internal...” - Vall0norg.openjfx:javafx-swing
,例如11
? 3)使用Java 11.0.5,Maven 3.6.2和插件org.openjfx:javafx-maven-plugin:0.0.4
可避免渲染问题(在单击“Load Report”按钮后会显示报告)。该应用程序是通过mvn clean javafx:run
启动的。
