Hi

I get the following stack trace (repeatedly) when programmatically instantiating and using a TextField.

Using Java 17 and JavaFX 16, JMetro 11.6.15.

Hi @ilacc1 Sorry for the late reply..

Can you provide a small sample app where this exception happens so I can check what's wrong?

Thanks!

dukke commented 2 years ago

I'll soon be closing this as won't fix if there is no small example app illustrating the problem, attached to this issue...

dukke commented 2 years ago

Closing this issue.

If you can attach a small example app where the problem shows up when running it, feel free to open it again.
