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:

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

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](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?

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

Thank you very much for your help.

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](https://www.azul.com/downloads/?version=java-11-lts&os=windows&architecture=x86-64-bit&package=jre-fx#zulu)

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](https://www.ganttproject.biz/download/free#lin) 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.
