Download and run the sample. Switch between 0 and 1 fixed columns a few times. After a while, the table changes, because ColumnDefinitionIF#editableIf() has been called on CVPriceColumnDefinition.

There's no change in stack trace before and after.

Before it's:

at vsa.vfx.experiment.demo.table.vfxtable.main.CVPriceColumnDefinition.editableIf(CVPriceColumnDefinition.java:40)
at vsa.vfx.experiment.demo.table.vfxtable.main.TextFieldColumnDefinition.collaborator(TextFieldColumnDefinition.java:44)
at vsa.vfx.experiment.demo.table.vfxtable.main.CVPriceColumnDefinition.collaborator(CVPriceColumnDefinition.java:18)

at vsa.vfx.control.table.vfxtables.VfxTableColumns$$Lambda$14/2025470705.call(Unknown Source)
at com.sun.javafx.scene.control.skin.TableRowSkin.getCell(TableRowSkin.java:80)
at com.sun.javafx.scene.control.skin.TableRowSkin.getCell(TableRowSkin.java:46)
at com.sun.javafx.scene.control.skin.TableRowSkinBase.createCell(TableRowSkinBase.java:652)

at javafx.scene.control.Control.layoutChildren(Control.java:574)
at javafx.scene.Parent.layout(Parent.java:1076)
...

After it changes to:
at vsa.vfx.experiment.demo.table.vfxtable.main.ColumnDefinitionIF.editableIf(ColumnDefinitionIF.java:43)
at vsa.vfx.experiment.demo.table.vfxtable.main.TextFieldColumnDefinition.collaborator(TextFieldColumnDefinition.java:44)

at vsa.vfx.control.table.vfxtables.VfxTableColumns$$Lambda$14/2025470705.call(Unknown Source)
at com.sun.javafx.scene.control.skin.TableRowSkin.getCell(TableRowSkin.java:80)
at com.sun.javafx.scene.control.skin.TableRowSkin.getCell(TableRowSkin.java:46)
at com.sun.javafx.scene.control.skin.TableRowSkinBase.createCell(TableRowSkinBase.java:652)
at com.sun.javafx.scene.control.skin.TableRowSkinBase.recreateCells(TableRowSkinBase.java:646)

at javafx.scene.control.Control.layoutChildren(Control.java:574)
at javafx.scene.Parent.layout(Parent.java:1076)
...

And sometimes I get:
at vsa.vfx.experiment.demo.table.vfxtable.main.CVPriceColumnDefinition.editableIf(CVPriceColumnDefinition.java:40)
at vsa.vfx.experiment.demo.table.vfxtable.main.TextFieldColumnDefinition.collaborator(TextFieldColumnDefinition.java:44)

at com.sun.javafx.scene.control.skin.TableRowSkin.getCell(TableRowSkin.java:46)
at com.sun.javafx.scene.control.skin.TableRowSkinBase.createCell(TableRowSkinBase.java:652)

        ...


I've tried to create some simpler sample, but was unsuccessful.
