editable table

Table editMode is quite limited:

• There is no good way of forcing the textfields in the table to be immediate - events will be sent when something else communicates with the server (one scrolls table for example)
• There is no listener in the table directly for listening to value change events in the container properties.

Here is a simple example on how to construct a container outside the table and listen to property changes in that.

IndexedContainer container = new IndexedContainer();
        container.addContainerProperty("name", String.class, "");
        for (int i = 0; i < 500; i++) {
            Integer rowid = new Integer(i);
            container.addItem(rowid);
            container.getContainerProperty(rowid, "name").setValue("Row " + i);
        }
        container.addListener(new Property.ValueChangeListener() {
            public void valueChange(ValueChangeEvent event) {
                Property p = event.getProperty();
                mainWindow.showNotification("A row was changed to " + p);
            }
        });
        Table t = new Table(null, container);
        t.setEditable(true);

Because editMode is quite limited, you might want to consider not using it and using a generated column instead.
