updateParams on custom fields

Question

Hi there ! 
 I want to use the updateParams function, but it doesn't work on custom fields for custom tables, for example I want to update a field named status_proc_c on the table cases_cstm, but after debugging I noticed that the field isn't considered because it has the key source and it is not of type db : 
 if (isset($fieldDef['source']) && $fieldDef['source'] != 'db') {
continue;
} 
 Here is the code I tried to execute : 
 global $db;
$fieldDefs = $GLOBALS['dictionary']['Case']['fields'];
$db_return = $db->updateParams('cases_cstm',
$fieldDefs,
array(
'status_proc_c' => 'status_proc_refused'
),
array(
'id_c' => $taskBean->parent_id,
)
); 
 Is there a way to bypass that ? That's a pity if we can only set the values for the principal table. 
 I checked on this article written by Matt Marum for my searches sugarclub.sugarcrm.com/.../use-of-prepared-statements-in-sugar-7-9 Thanks in advance for your feedback ! 
 Have a nice and safe day,

Enes, 
 You don't have to copy all the code but you should look at how DynamicField handles the fact that the core function only works on "source" => "db" field definitions. Effectively it temporarily (for the scope of the function call) changes that attribute to "db" from "custom_felds" like this 
 array_merge($field, array('source' => 'db')); 
 which is simply appending an attribute to the array thereby overwriting any original value. In that code the field defs array passed only seems to be altering that one attribute for the field in question. 
 I would think that you should be doing the same in your code so that updateParams works for your custom field. 
 Thanks,
