Dear Dom,
the noted date (20230223) is from a commit which states that "json-rgf.cls" got updated, so unsure
whether that version of ooRexx 5.0 was working with fxml_99 or not (I probably tested the app, but
cannot recall, too long ago).
Today I took the time to skim over the commits of those four JavaFX samples that cause sometimes a
flurry of callbacks from Java to ooRexx (directories in BSF4ooRexx850/samples/JavaFX):
*fxml_25: demoTableViewSimpleController.rex*
2020-07-15 r733 TableView example with editable cells
2022-08-10 r951 new branch 850
*fxml_26: demoTableViewComboBoxCellController.rex*
2020-07-15 r734 TableView example with checkboxes for cells (extending
fxml_25)
2022-08-10 r951 new branch 850
*fxml_27: demoTableView.rex*
2020-07-15 r732 TableView example with checkboxes and datepicker for cells,
move to directory
(extending fxml_26)

/2019-03-13 r653 warn user if not on ooRexx 5.0beta which is needed for
stable multi-threading/
2022-08-10 r951 new branch 850
Probably all four JavaFX applications were tested (run) when creating the new BSF4ooRexx branch
"850" on 2022-08-10. So I assume that with that beta version of ooRexx 5.0 the samples would ran.
However, there seem to have been occasionally problems on Windows (crash at termination) which could
be solved by adding "call sysSleep 0.01" right before exiting the Rexx program.

Sorry that my hack proved to be a dud. I guess this will need a more knowledgeable head to figure

Please there is nothing to be sorry about, au contraire, thank you *very* much for all of your
efforts and attempts, which are highly appreciated!
Do you know when the fxml_99 sample stopped working, or alternately have there always been
issues? I’ve been trying different out a few scenarios and I’m able to get hangs on both Windows
and Ubuntu at different times – on Windows at startup before the dialog appears and on Ubuntu
when I delete an item. This is running ooRexx 5.0 with BSF4ooRexx850. On Windows I’m using the
Bellsoft JRE which includes JavaFX and on Ubuntu openjdk + openjfx packages
The last commit stems from February, 23rd, 2023, so I assume it worked at that point in time. Yes,
there were problems earlier, however there were gone when Rick was working on the threading issues
reported back then.
