js function copyFieldValues fails when "Options per Line" is set

To reproduce on demo site (with current data):

• To search, limit to individuals
• select the first three individuals
• select Batch update via profile
• select Supporter profile
• Place checkbox in one of the options for the field "What kind of beans do you like?"
• click the copy icon

(I created the custom data field "What kind of beans do you like?" - it can be re-create - the only thing needed to trigger the error is a non-null value for the options per line.

Instead of copying the value all the way down, it unchecks the value.

The culprit seems to be in CRM/common/batchCopy.tpl, in the copyFieldValues() function here:

if ( elementType == 'radio' )

{ firstElementValue = elementId.filter(':checked').eq(0).val(); elementId.filter("[value=" + firstElementValue + "]").prop("checked",true); }

else if ( elementType == 'checkbox' ) {
// handle checkbox
// get the entity id of first element
var firstEntityId = firstElement.parent().parent().attr('entity_id');

If we are displaying the values in columns, they are nested in a table, so we can't assume that we'll find the first entity with parent().parent(). Not sure the best way to find it though...
