JTable and DefautlTableModel not refreshing

Question

MyTableModel extends DefaultTableModel, everything looks and works correctly.

I have one editable column, and the setValueAt() is being called, and the database updated.

However the table itself is not being refreshed ?

I override, getColumName(), getRowCount(), isCellEditable(), getColumClass(), and setValueAt() - which gets called, and fires the database update. The model is backed by a list, which is updated in setValueAt().

And the model is set simply by myTable.setModel(myTableModel);

Answer 1

Do you call super.setValueAt() in your code?

Looks like your changes skips events firing.

Answer 2

Call fireTableCellUpdated() at the end of setValueAt() method. It must help you.

Answer 3

Maybe you need to refresh the cache of the TableModel. In order to do it you can override fireTableDataChanged() and call the super method at the end of the overriding.
