I want to have a confirmation window when the user pressed the submit button. Depending on the user choice, the data passed to the server will be different.
Thanks a lot for your help, the code allways return false for debugging porposes.
Unfortenatly the use of checkOnUpdate and CkecOnSubmit not solves my problem. I don't want to look for changes made in the form but only check if a particular field (cost) have values. I have various scenarios (or use cases), but to simplify, imagine the following:
This field (cost) by default, are calculated (no needs user input). But the user have the possibility to input some value in the cost and in this case we don't want the cost value to be replaced with a calculated value without user authorization. In this case, and if the cost field have values, we should ask the user for a boolean choice: Yes or No (replace or not replace with automatic calculations).
