But this error showed up in the status bar and I though I should report it. gragon: I launched Netbeans. Then I selected the third (last) tab in a TabPane (JavaFX). farseenabdulsalam: I started up NetBeans 8. Monet scenbuilder plugin was already installed. A JavaFX FXML Application project that I've created even before installing the plugin opened up, and so did the main FXML file. I was already on the Design tab. Then this error showed up.
