Grid: How to continue editing Rows with failed Validation?

Vaadin 6 / 7 / 8 Framework UI

Hello Vaadin-World,

Like the title already says, i want that the User should be able to edit rows, although the validation of some fields fail. Now, if the a Field has a Component Error, i can only continue if the error has been eliminated.
I cant find the right method or a workaround. It would be great if someone know more.

Here a code section

[code]
this.setWidth("640px");
this.setHeightMode(HeightMode.ROW);
this.setEditorEnabled(true);
this.setEditorBuffered(false);
this.setColumnReorderingAllowed(false);

wochenAz = new TextField();
Grid.Column wochenAZColumn = getColumn("wochenAZ");
wochenAZColumn.setEditorField(wochenAz);
wochenAz.addValidator(new RegexpValidator("[^a-z]
+[^A-Z]
", ""));
[/code]
