How to set column's cell value depending on changes in other column?

Question

I have 3 column + 10 rows in celltable. value1Column, value2Column, RecordState

1 | 2 | *

2 | 4 | -

:

9 | 5 | -

10| 5 | *

Whenever user changes values either value1 or value2 then immediately cell related to that record set to * in RecordState column.

How to set * in RecordState column on value changes?

How to use setFieldUpdater to update values in column ?

value1Column.setFieldUpdater(new FieldUpdater() { public void update(int index, RecordVO object, integer value) { //How to set * in RecordState column ? }

Answer 1

You would need to redraw the table to update the other column. So in the field updater for value1Column you would call something like RecordVO.valueUpdated() and then call CellTable.redraw(). Your column for the RecordState table should check if RecordVO.isUpdated() and output a value accordingly.
