[ solved ] Error on workflows task after last updated

[rslemer]

in workflow details (summary list) error occurs, even I try removed a workflow task with error

The requested URL /<br /> <b>Notice</b>: Undefined property: stdClass::$id in <b>/usr/share/master/Smarty/templates_c/dd2a9e5625156df4847183550f07f6312ab52166_0.file.TaskSummaryList.tpl.php</b> on line <b>157</b><br />index.php was not found on this server.

But I can remove all workflows in general workflow list
