NPE in VirtualFlow

[Mario Ivankovits]

Thanks!

I’ve created the issue for this https://javafx-jira.kenai.com/browse/RT-39752 and will try to create a test case in the next few days.

Best regards,
Mario

The closest I can find that is somewhat related to TableView and NPE, but not exactly the same issue is the following JIRA:

https://javafx-jira.kenai.com/browse/RT-39624

Please file a JIRA once you have a reproducible test case ready. Here is a link on how to file a bug report with us:

Thanks,

Hi!

Every now and then I get the exception down there (starting with JavaFX 8u40-b18 if I remember correctly)

It seems it has something to to with the fact that the items list of one of my TableViews gets cleared and so no cells are visible any more.
I was not yet able to always reproduce that. I will try to do that, but probably someone has a clue anyway?

BR,
Mario
