I have a problem when I submit the form the page workflow configurations "thresholds that affect Workflow" are not good.
Below is a screen showing the steps to reproduce the problem. If we do not change the values ​​on the role the value passed to "ADMIN".

manage_config_workflow_set.php

The current code:

foreach( $t_valid_thresholds as $t_threshold ) {
$t_access_current = config_get_access( $t_threshold );
if( $t_access >= $t_access_current ) {
$f_value = gpcget( 'threshold' . $t_threshold );
$t_value_current = config_get( $t_threshold );
$f_access = gpcget( 'access' . $t_threshold );
if( $f_value == $t_value_current && $f_access == $t_access_current ) {

If new value is equal to parent and access has not changed

            config_delete( $t_threshold, ALL_USERS , $t_project );
        } else if( $f_value != $t_value_current || $f_access != $t_access_current ) {
            # Set config if value or access have changed
            config_set( $t_threshold, $f_value, NO_USER, $t_project, $f_access );
        }
    }
}

• $ f_value: is the old value
• $ t_value_current: corresponds to the new value

The comment does not match what is being done:

If new value is equal to the parent and access HAS not changed

More functionally if it is the same as the parent project parameterization why delete it if the parent project that you do not want to change the sub-project is changed.

the code should look like :

foreach( $t_valid_thresholds as $t_threshold ) {
    $t_access_current = config_get_access( $t_threshold );
    if( $t_access >= $t_access_current ) {
        $f_value = gpc_get( 'threshold_' . $t_threshold );
        $t_value_current = config_get( $t_threshold );
        $f_access = gpc_get( 'access_' . $t_threshold );
        if( $f_value != $t_value_current || $f_access != $t_access_current ) {
            # Set config if value or access have changed
            config_set( $t_threshold, $f_value, NO_USER, $t_project, $f_access );
        }
    }
}
