Struts 2 persistance for Table values

How to persist table values while changing each tab?
Normally values containing text box will persist.
ie,<s:textfield name="myData" />

I have list of values which is populated using iterator Tag into a table.
But,while triggering each tab all text box values will persist, except these table values.
How can we solve it? :(

i solved it like this:


Earlier i put these list values into existing object which need to populate other values into jsp page.Now i changed as list values are put in a separate object .then first time got values from DB then put it into a Map as separate object.So thereby manage the data as our requirement .:)


Thanks all
