I wanted to add a custom field validation method, so I followed the example in the how to's as below.
But I always get the error messages below when the method returns false. (Works fine if validation is true.) Did something change in Dataface since the example was written? Or I'm I missing something here?

code:
-----------------------------------------
function Proteins__validate( & $record, $value, $params){
$result = true;
$proteins = explode(";",$value);
foreach($proteins as $k=>$line){
$seq=trim($line);
if ($seq !='') {
$ProteinRecord = df_get_record ( 'Proteins', array('Name' =>'='.$seq) );
if ($ProteinRecord == null){
$params['message'] = "Sorry, protein name: $seq not found.";
$result = false;
}// end if null
} //end if seq =''
} // end foreach
return $result;
} //end function

--------------------------------------------------------------------------------
Error returned:

Hi,

I haven't forgotten about this question... I haven't been able to test this out to figure out the problem.
In the mean time, you can achieve your goal by creating a beforeSave() trigger that does the processing. I believe there is an example of this in the Getting started tutorial in the section on triggers.

More later..
