anyone on this issue? please help me!

ups.. I think you found a bug!!

try adding this on file /administrator/components/com_muscol/models/artist.php line 59

$this->_artists_data[] = new stdClass();

don't work...
work if i select a related artists and work if i change this related... but if you want to remove any association can not.
should add a blank space in artists list ... or something similar..

Maybe this is the same bug. Some artists which are related to a deleted artist, show all artists as related instead

well the code does exactly that! it adds a blank space!! (at the BOTTOM of the list)

check it out!! :lol:

this is the code in my file, but i dont see a blank space in the list

function getArtistsData()
		{
			// Lets load the data if it doesn't already exist
			if (empty( $this->_artists_data )){
				$query = ' SELECT id,artist_name FROM #__muscol_artists '.
						' WHERE id != '.$this->_id.
						 ' ORDER BY letter,class_name';
						$this->_artists_data[] = new stdClass();
						$this->_db->setQuery( $query );
				
				$this->_artists_data = $this->_db->loadObjectList();
			}
			
		return $this->_artists_data;
	
	}

the code its not on the correct line. maybe I misspelled the line

you have to put the "$this->_artists_data[] = new stdClass(); "

just AFTER "$this->_artists_data = $this->_db->loadObjectList(); "

perfect!

awesome
