JavaFX NullpointerException crashes GUI of Steuertabelle #65

Open cediwelli opened 2 years ago

cediwelli commented 2 years ago

What happens: The Steuertabelle will gray-out and loses all of its contents. Adding new rows or trying to use any of the other controls on the right is ineffective.

How it looks: https://imgur.com/a/Z2GLbuj

How to reproduce: I can not reproduce the Error easily. It usually happens when deleting rows from the Steuertabelle but not always.

I am on Linux cwm10 5.10.0-18-amd64 #1 SMP Debian 5.10.140-1 (2022-09-02) x86_64 GNU/Linux Java version:

openjdk 17.0.4 2022-07-19
OpenJDK Runtime Environment (build 17.0.4+8-Debian-1deb11u1)
OpenJDK 64-Bit Server VM (build 17.0.4+8-Debian-1deb11u1, mixed mode, sharing)

terminal output:
