Error when setting the default value to the form element value from previous submission.

Can you post the code you are using to set the default value.

I'm having a similar issue when using the Form API to build a "select_or_other" field.

For me, it's not related to using the default value or not. What happens is that the selected options in the $submission array for a Webform are not able to be read.

Here's what I mean:

My abbreviated code for the form itself:

$form['submitted']['submit_this_reflection_to'] = array(
	'#title' => t('Submit this Reflection to'),
	'#title_display' => 'before',
	'#required' => 1,
	'#weight' => 100,
	'#options' => array(
		$agency_admin->mail => $agency_admin->mail,
		'1@one.com' => '1@one.com',
		'2@two.com' => '2@two.com'
		),
	'#default_value' => '',
	'#type' => 'select_or_other',
	'#other' => t('Other Email'),
	'#other_title' => t('Submit this Reflection to Other Email'),
	'#select_type' => 'checkboxes',
);

The important line here is the #options being set. For me, I'm using the Form API so I can insert a variable as one of the options while allowing the users to set an option themselves.

With all options selected and no "other" element added, the $form_state['values']['submitted'] used to save to the db looks like this:

$submission->data => Array
    [4] => Array
        (
            [0] => Array
                (
                    [1@one.com] => 1@one.com
                    [2@two.com] => 2@two.com
                    [agencya_admin@test.com] => agencya_admin@test.com
                    [select_or_other] => 0
                )

The problem seems to be that the $submission->data[4][0] is made up of more arrays. When I try to use the $submission object that is created by retrieving the data from the db, all the email addresses are just blank arrays.

Specifically, each value in $submission->data[4]['value'][0] just prints out as Array() rather than as the email address.

In the db, the row for the submission looks like the attached.

Any ideas? Is this expected?

Did you try setting
'#multiple' => TRUE,
