Table.discard() does not revert displayed values

Vaadin 6 / 7 / 8 Framework UI

Hi,

there seems to be a problem with either a Table component or my understanding.

When I invoke table.commit() data gets propagated to the containers.

When I invoke table.discard() - data does not get propagated to the container, but the displayed values are not reverted back…

Based on the doco:

Discards all changes since last commit. The object updates its value from the data source.

It does not seem to be happening.


cancelButton.addListener(new Button.ClickListener() {

            public void buttonClick(ClickEvent event) {

                table.discard();
                table.requestRepaint();
               
            }
        });

What do I miss?
Vaadin 6.4.7

p.s. Great and fun framework btw!

Hi,

Table is a field which value is selection (practically item identifier(s) of container data source). For example Table can be used instead of a Select component. commit() and discard() methods work with this selection value and with Table’s property data source. They don’t affect possibly created fields inside the table (like in Form).
