command button does not work after getting rendered

Hi,

i have a requirement, if first command button value 'check mapping for Attendee' is click, it should render a new button namely 'Import Attendee'. The problem is when i click first button if hundred times, it keeps the value of input file but when new rerender button got visible 'Import Attendee'. This button does not work on the same file. if i remove rerendered attributes from the 'Import Attendee' button. it works on input file as expected. but i want to show it after first button 'Check mapping for Attendee' clicked. I shall be grateful to you for your kind cooperation. Thanks in Advance.

i am getting for the rerendered attribute (attendee==true) from controller.

    Hi Akash,

    Thanks for your kind response. i almost lost the hope of fixing it. Actually after your answer when i again visited the controller i checked that i have made the boolen importattendee a transient keywords and that's where it caused the problem. i am really thankful to you.
