how to loop inside a dialog?

[p_meet]

hi
Description:
my dialog has a text field .
wen i press next, the text field is being validated.
If the entry is valid i go to next frame, else i show some user response popup.
If user wants to continue i want to go next frame else i want to show the same text field frame again.

problem:
i can only validate text field wen next is pressed(is the any other way?). It ll call query exit. I put my validating logic there. How to get to call same dialog again?
intializeUI method i called , it compiled buit isnt working. any sugesitons?

got the solution.
there is a method which can be called in queryExit through the function argument u get.
returnValue(boolean)

set it to false and u wont go to next panel
