Hi,

What is scope of binding bean?

[abcd1]

hii
sorry for the late reply

scope is session

[ilya_shaikovsky]

binding should be request scoped.

thanks for the reply...

but i cannot change the scope to request

Hi,

Then you'll be constantly getting such errors. Session-scoped binding for components is not recommended for several other reasons also. Why do you need it?

[abcd1]

on selection of rows i need to go to backend..
and also i need to get the selected row id. from backend like this.
as my bean needs to be in session i am binding the table binding to the same session bean.

Iterator iterator = getSelectionGR_POS_7155().getKeys();
while (iterator.hasNext()) {
 Integer key = (Integer) iterator.next();
 GR_POS_7155.setRowKey(key);
 GR_POS_7155_TableBean obj =(GR_POS_7155_TableBean)GR_POS_7155.getRowData();

int indx = GR_POS_7155_List.indexOf(obj);
setSelectedRowNo(indx);
}

[nbelaevski]

Create separate request-scoped bean.

ok
thanks for the reply..
i will try to do that
