JFoenix | JavaFX Material Design Library

The onAction method is for generic actions and not every components have that method. if you want to fire an event when the user click the button you can use

Referring to the documentation, the argument should be using instead

See this comment on a pull request for jfoenix, https://github.com/bisq-network/bisq/pull/5835:

Running the desktop app only works on JDKs 11 through 15 until sshahine/JFoenix#1205 is fixed. Right now, attempting to run on JDK 16+ will result in a Cannot invoke "javafx.scene.Node.getLayoutBounds()" because "this.textNode" is null error.

So you are experiencing a known issue.

Probably the JDK 15 will works?

Yes.

Downgrade to JDK 15.

I assume it is just a JDK issue, because that is what the comment says, and an additional downgrade to JavaFX 15 in not required.

The asker tried a downgrade of just the JDK version and notes that it works in comments:

I tried to downgrade to jdk 11 and it works and then tried to do it in jdk 15 and flawlessly works.

If you continue to experience issues such as this with jfoenix, contact the jfoenix project maintainers directly.

As you can see in the Stack Trace, Error is coming from the place de.some.project.controller.ControllerConfiguration.connectedConnectorsController(ControllerConfiguration.java:156)

You are referencing a wrong place I think. Actually Error say you try to convert ConnectorFittingResultController class to ConnectedConnectorsController class at ControllerConfiguration.java:156 Please check that point.

I downloaded the most recent versions of SceneBuilder (17) and jfoenix (9.0.10) and dragged the jfoenix jar to the library pane in SceneBuilder to import it. The import completed, JFXTabPane was displayed in the library. When I tried to drag a JFXTabPane from the library catalog into a scene, scene builder started behaving oddly (it broke and did not render the scene being built correctly). So it JFXTabPane still doesn't work with SceneBuilder. I advise you file an report with jfoenix to ask them to fix the issue (they have an issue tracker on their github site).

The asker did note in comments that, under the setup they are using:

jfoenix 9 is displaying the JFXTabPane

That might be due to using a different version of SceneBuilder than the version 17 I used.

If you continue to have issues, just use a plain TabPane in your FXML document rather than a JFXTabPane. I looked at the source and, functionally they are the same, JFXTabPane inherits from TabPane. In your code, create a new JFXTabPane and replace the TabPane injected by scene builder with your new pane (setting the children and properties the same as the fxml), and you should be fine to design in SceneBuilder but still use a JFXTabPane in your actual app. It is a bit of a hack, but not too bad.

There may be similar issues with using other jfoenix controls in SceneBuilder (I don't know, I haven't tried them), but basic jfoenix controls like JFXButton appeared to work in SceneBuilder fine, so perhaps it is on the JFXTabPane which experiences these issues.

For further information on troubleshooting SceneBuilder custom component import, see the following document (though it may not assist in all cases):

• How to create an FXML file for an already created new component in java than add it to scene builder?

The answer to which features a SceneBuilder import troubleshooting section.

I would implement FX property pattern in OMission class:

From your code is not clear if the Tableview is editable. Assuming the TableView is missionTable, try:

The issue here appeared to be a compatibility issue of the JFoenix dependency as the stack trace indicated:

Caused by: java.lang.UnsupportedClassVersionError: com/jfoenix/controls/JFXDialogLayout has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Updating the JRE or downgrading the dependency fixes the issue.

It is a bug in logback 1.3.0-alpha5
