OK - I hate to post so often, but I am running into some issues with my update to 3.3.3.

I have created a customized version of the price option edit form and added a multi-select list to it. It displays correctly, but when the form is submitted the list is not in the elements of the form. I can see it in the $_POST variables when I debug, but it isn't a part of the form object. Previously I was able to get the value from the form object. Is this new behavior?

Thanks for your (added) help,

IRC appears to be down right now, so I'll post here.

This is the code I have been using to add the list to the form.
if($formName == 'CRM_Price_Form_Option' && $action == 'update'){
//generate list of memberships to add to form
$group_list = getGroupList();
//get any acl's that already exist
$oid = $form->getElement('optionId')->getValue();
//no oid means this price option is being added
if($oid){
  $groups_selected = getAcl($oid);
}
// set default values
$form->setDefaults(array('groups'=>$groups_selected));
$form->addElement('select','groups','Groups',$group_list);
$element = $form->getElement('groups');
if(!$oid){
  $element->updateAttributes(array('disabled'=>true));
}
$element->setMultiple(true);
}
In my postProcess hook I have the following code

function memberprice_civicrm_postProcess( $formName, &$form ){
  $action = $form->getVar('_action');
if($formName == 'CRM_Price_Form_Option' && $action == CRM_Core_Action::UPDATE){
$price_option_id = $form->getElement('optionId')->getValue();
  $acl_group_id=$form->getElement('groups')->getValue();
I get an error at
$form->getElement('groups')->getValue() - Non existent html element 'groups'.

In debug mode I can see that the submitted form in postProcess does not have the select list that I added in buildForm.

OK, that worked but I don't understand why. I was setting $action by getting it from $_GET since I wasn't able to get it from $form at the time. As I stepped through the code I saw the list added to the form (it was actually in the $form object in the debug window) and it displayed correctly.

I changed to getting $action from the $form var as you instructed in a previous post, and switched to using CRM_Core_Action::UPDATE as you asked, and now the list is added to the form AND it is submitted and handled correctly in postProcess. I guess I assumed that if it was being added to the form and displayed it would be there to be processed. As I write this I am literally switching between the two ways of checking the $update variable, stepping through it in debug mode and the code path doesn't change, only method of getting and checking $update. Can you let me in on the secret

Thanks for your help and explanation.
