Better Workflow > Assets integration

gistfile1.txt

In ft.assets.php add this to the top of the pre_process function:

	/**
	 * Pre Process
	 */
	function pre_process()
	{
		// -------------------------------------------
		//  Get the exp_assets_entries rows
		// -------------------------------------------
		
		// BWF support
		$from_bwf = FALSE;
		
		if (isset($this->EE->session->cache['ep_better_workflow']) 
			&& isset($this->EE->session->cache['ep_better_workflow']['preview_entry_data'])) 
		{
			$draft_data = unserialize($this->EE->session->cache['ep_better_workflow']['preview_entry_data']->draft_data);
			
			if (isset($draft_data['field_id_' . $this->field_id]))
			{
				$draft_rows = $draft_data['field_id_' . $this->field_id];
			
				// build an array Assets can work with
				$rows = array();
				foreach ($draft_rows as $key => $val)
				{
					if ( ! is_array($val))
					{
						$rows[$key] = array();
						$rows[$key]['file_path'] = $val;
					}
				}

				$from_bwf = TRUE;
			}
		}	
		
		if ( ! $from_bwf)
		{
		   // the original if/else conditional goes in here
		}

		// -------------------------------------------
		//  Get the files
		// -------------------------------------------

		// the function continues here...
	}

Which Assets version is this for? I added this code and got an error when publishing a draft.

What version of assets is this valid for?
