Hello:

i'm trying create a subpanel following subpanels of Cases and http://www.sugarcrm.com/wiki/index.p...nels_Explained

but i have a problem.

My layout_defs

$layout_defs['Contratos'] = array(
        // list of what Subpanels to show in the DetailView
        'subpanel_setup' => array(
                'history' => array(
                        'order' => 30,
                        'sort_order' => 'desc',
                        'sort_by' => 'date_modified',
                        'title_key' => 'LBL_HISTORY_SUBPANEL_TITLE',
                        'type' => 'collection',
                        'subpanel_name' => 'history',   //this values is not associated with a physical file.
                        'module'=>'History',
                        
                        'top_buttons' => array(
                        array('widget_class' => 'SubPanelTopCreateNoteButton'),
                        array('widget_class' => 'SubPanelTopArchiveEmailButton'),
            array('widget_class' => 'SubPanelTopSummaryButton'),
                        ),
                        
                        'collection_list' => array(
                                'notes' => array(
                                        'module' => 'Notes',
                                        'subpanel_name' => 'ForHistory',
                                        'get_subpanel_data' => 'notes',
                                ),
                        )
                ),
        ),
);

i got the error:
Fatal error: Call to a member function getQuery() on a non-object in /var/www/SugarCRM/data/SugarBean.php on line 1753

ok, if i change 'module' => 'Notes' for 'module' => 'History'
the error is:

Warning: aSubPanel::require(modules/History/subpanels/ForHistory.php)

this error is obviusly
