Hi
In my module I am adding a custom code button to ProspectLists detail view but when I do that it removes existing buttons and display only my button

CODE


function post_install(){
    require_once('modules/ModuleBuilder/parsers/ParserFactory.php');
    $parser = ParserFactory::getParser('detailview', 'ProspectLists');
    $buttons = $parser->_viewdefs['templateMeta']['form']['buttons'];


    $SQLButton =
        array(
            'customCode' => '<input type="button" class="button" onclick="location.href=\'index.php?module=ProspectLists&action=actionanem&record={$fields.id.value}\'"
			value="Test Me">',
        );

    $numItems = count( $parser->_viewdefs['templateMeta']['form']['buttons']);
    echo $numItems ." -first<br/>";

    $parser->_viewdefs['templateMeta']['form']['buttons'][]['form']['buttons'][]= $SQLButton;
    $parser->handleSave(false);

   

    return;
}

the functions are working perfectly but only the button is the problem

Thanks
