GWT-Ext EditorGridPanel problem

[stwr]

Hi,

I'm experiencing problem with EditorGridPanel.
Its selection model is CheckboxSelectionModel.
The panel contains several editable text fields and combo boxes.

Use Case:
1. Select first row (check the corresponding check box)
2. Change value of some text field or combo box in the first row

Result:
Row is automatically deselected (check box for first row is deselected)

In the result an user has to select the corresponding check box again always after some change in the row.

How can I avoid such behavior?

Thanks in advance,
stwr
