Unknown property 'void.name'
Error is in expression '{!pitem.name}' in component <apex:outputText> in page timeentrypage
This should work. Can you provide your salesforce org login credentials so I can have a look. You can contact me either on my gmail id: neetu.bansal.5@gmail.com or Skype id: neetu.bansal.5
