Caused by: java.lang.IllegalArgumentException: Item with specified ID does

Hi,

I have use grid in my panel with delete column and one add button in panel which add the new row in grid.
when I delete the row from grid then it works, but when I add a new item then some times it gives following Exception.

I have refresh the grid while deleteing the item.
@Override
    public void refresh() {
        locoContainer.removeAllItems();
        locoContainer.addAll(dataList);
    }

Exception: 
Caused by: java.lang.IllegalArgumentException: Item with specified ID does not exist in data source    at com.vaadin.ui.Grid.scrollTo(Grid.java:5408)[69:com.vaadin.server:7.6.5]    at com.vaadin.ui.Grid.scrollTo(Grid.java:5386)[69:com.vaadin.server:7.6.5]    at com.knorrbremse.icom.leader.ui.components.grid.RestoreSelectionListener.selectByBean(RestoreSelectionListener.java:64)    at com.knorrbremse.icom.leader.ui.components.grid.RestoreSelectionListener.detach(RestoreSelectionListener.java:77)    at sun.reflect.GeneratedMethodAccessor89.invoke(Unknown Source)    at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)[:1.8.0_40]    at java.lang.reflect.Method.invoke(Unknown Source)[:1.8.0_40]    at com.vaadin.event.ListenerMethod.receiveEvent(ListenerMethod.java:508)[69:com.vaadin.server:7.6.5]    ... 57 more

Is any pointer to solve this problem?
 

Thanks Tatu Lund,

kindly tell me how can I handle this exception?

on delete action I have to remove the item from container and refresh it.

Another thing is it does not through exception each time.it occors randomly.
