I open a popup besides my existing window where the user can choose a date from a calendar.
By clicking on a specific date the date will be written in a form in the other window (the opener).
When the user now moves in the popup window back and forth, like changing the month, the function:
won`t work anymore, the opener value got lost or overwritten by the reloading popup window
any ideas how can i solve this problem or work around?
