The problem is that I am using ajaxed form with clientside validation which uses Drupal.settings to get some data. As an example to validate age I set following data to drupal settings:
drupal_add_js(array( 'viewpoint_profile' => array( 'year' => date('Y'), 'month' => date('m'), 'day' => date('d') )), 'setting');
But whenever form is reloaded with ajax it merges above settings to Drupal.settings and if on first call
Drupal.settings.viewpoint_profile.year == 2011, after ajax reload it is
Drupal.settings.viewpoint_profile.year == array(2011, 2011), so I can't use this in js as a string any more.
So basically it would be nice to clear settings for viewpoint_profile before adding them, but I didn't manage to find how? or may be there is another way to solve this problem?
