When deleting a Check, the Decorator is not deleted

[goshik81]

Hi. I try apply validations for Table.
But when i remove Check object Decoration is not Deleted.

ValidationTest.zip

How can I use ValidatorFX for each row in TableView?
Thanks.

I am not sure what the problem is here. You could try to call validator.validate() explicetly after validator.remove(check);. This should trigger a re-evaluation of the validation.

I added check.clear();
now I have code like this:

    private void removeCheck() {
        if (check != null) {
            check.clear();
            validator.remove(check);
            check = null;
            checkedItem = null;
        }
    }

But after row deletion I have an error:

Also if I add 10+ records and try scroll records up and down, I have this error:

Do you have an example how use validations with TableView?

[effad]

This smells like a "update outside JavaFX-Thread"-Problem (which it cannot be from the sources you sent me). Maybe the updateItem()-call happens within a rendering-pulse and we're not allowed to modify the scene graph at that time. But I must admit, this is guesswork. Interestingly enough though, there is no "net.synedra..." in the stack traces above.

Unfortunately I do not have an example of how to use validations inside TableView.

There are no problems with decoration "StyleClassDecoration"
For now I create "class TableRowDecoration extends StyleClassDecoration"

and use it like this:

.decoratingWith(TableRowDecoration::createRowDecoration)

ValidationTest.zip

But I think it is necessary to fix the class. "GraphicDecoration"
