By testing Seblod version 3.8.3 and Joomla 3.5.1 I found a malfunction.
All my forms that contained a test user ID field filled dynamically no longer worked.
After checking I located the problem with the file \ plugins \ cck_field_live \ joomla_user \ joomla_user.php
When selected the User id field the variable returned is of the type 'integer'.
if ( is_array( $live ) ) {
if ( $excluded != '' ) {
$excluded = explode( ',', $excluded );
$live = array_diff( $live, $excluded );
}
if ( empty( $live ) ) {
$live = $default;
} else {
$live = implode( ',', $live );
}
} elseif ( $live == '' ) {
$live = $default;
}
In the loop
elseif ( $live == '' ) line 82 this causes an error of choice.
We must therefore change the test elseif ( $live === '' ) and then everything is ok.
I hope this helps you.
