Text doesn't show in task columns

[Eleanor]

Whenever I add a task and edit the details in task properties, no text appears under the task columns for task name, begin date, end date etc. The following error message has appeared:

Something went wrong

com/sun/javafx/scene/control/behavior/TextBinding
com.sun.javafx.scene.control.behavior.TextBinding

And this is the log:

Many thanks,

AFAIK, GP is supported with Java 11. Your are using Java 19.
Try v11 and tell us… ; )

MacOS Monterey et puce M1 max

The file looks good. To follow your advice, I started by installing: bellsoft-jdk18.0.1+12-macos-aarch64, You don’t want Java 18, you want Java 11. You don’t need jdk, you need JRE. And you need “full”, not the standard. Here is the link: https://download.bell-sw.com/java/11.0.15.1+2/bellsoft-jre11.0.15.1+2-macos-aarch64-full.dmg without any result unfortunately Did you run GanttProject from ZIP distro?

[Eleanor]

Uninstalled Java 19 and installed Java 11, it is now working.

Thank you very much for your help.

I have the same problem. I am using Azul. What can I do to get this work?

You need Java runtime with JavaFX modules. On Azul site it is called JRE FX: https://www.azul.com/downloads/?version=java-11-lts&os=windows&architecture=x86-64-bit&package=jre-fx#zulu

[arkadianriver]

I was having this problem with the generic zip bundle running on Arch linux, using OpenJDK 25 and OpenJFX 25, running the ganttproject script with $OPENJFX_JAVA_OPTIONS --add-modules=ALL-MODULE-PATH added to the $JAVA_COMMAND call.

Noticing on page GanttProject - Download that it’s tested on Java 17, I downgraded to liberica jdk17 and it now works fine.

But, has anyone gotten task table text showing up on more recent open versions of Java with JFX? Was there a setting I was missing?

Thanks for any info.
