Please post related code.
Take into consideration that you should process only first input while triggering such action. So if using support in source input - make it ajaxSingle = true, and if using some button or link add the same ajaxsingle declaration and add process="firstInputId" also.
Thanks very much for yours messages and for helping.
@nbelaevski yes if i had some code my question will be more understandable but in real application there are many java classes which deal with this operation and also many rich faces code, my post was simplified and tried to synthesize the "real" issue.
@ilya_shaikovsky i will use your suggestions and try to adjust them in the right way.
All the best,
