data transfer from one GUIBB to another

Hi,

we have created 3 tab with few column editable. all three tab uses same feeder class and same columns.

our requirement is when user modified any column data and switch tab then modified data must be visible in other tab. 

example:

if i change data on first row connid from 0017-> 0012 and user click on TAB2 then for first row connid must be 0012.

Thanks.
