Newbie a lot of "Cannot retrieve item null for widget" errors in logback

intruder82 · December 28, 2015, 2:25pm

Hello,

My openhab server runs and till now it’s quite stable. I was binding mylights and had to turn on debug mode in the logback. It’s not critical, but it would be interesting to know why am I getting a lot of “Cannot retrieve item null for widget” when I open the setup in browser or my android phone.

This is what I get when I enter my openhab setup through webpage on pc:

2015-12-28 15:56:25.884 [DEBUG] [.o.u.w.i.servlet.WebAppServlet] - Servlet request received!
2015-12-28 15:56:25.898 [DEBUG] [.o.u.w.i.servlet.WebAppServlet] - reading sitemap Santariskes

2015-12-28 15:56:25.901 [DEBUG] [o.u.i.items.ItemUIRegistryImpl] - Cannot retrieve item null for widget org.openhab.model.sitemap.Frame

And this is what I get when I open the set up in openhab android app:

maybe someone can explain the principle of this error… couldn’t find a description why it’s caused and how to solve it…

Part of the stemap…:

sitemap Santariskes label="Mano Namai"
{
    Frame {
        Group item=g3A label="Trečias aukštas" icon="firstfloor"
        Group item=g2A label="Antras aukštas" icon="groundfloor"
        Group item=g1A label="Pirmas aukštas" icon="cellar"
        Group item=Garazas label="Garažas" icon="garage" 
    }
    Frame label="Weather" {
        Text item=Weather_Temperature valuecolor=[Weather_LastUpdate=="Uninitialized"="lightgray",Weather_LastUpdate>90="lightgray",>25="orange",>15="green",>5="orange",<=5="blue"] {
            Frame {
                Text item=Weather_Temp_Max valuecolor=[>25="orange",>15="green",>5="orange",<=5="blue"]
                Text item=Weather_Temp_Min valuecolor=[>25="orange",>15="green",>5="orange",<=5="blue"]
                Text item=Weather_Humidity
                Text item=Weather_Humidex
                Text item=Weather_LastUpdate visibility=[Weather_LastUpdate>30] valuecolor=[Weather_LastUpdate>120="orange", Weather_LastUpdate>300="red"]
            }
             Frame {
                Switch item=Weather_Chart_Period label="Chart Period" mappings=[0="Hour", 1="Day", 2="Week"]
                Chart item=Weather_Chart period=h refresh=6000 visibility=[Weather_Chart_Period==0, Weather_Chart_Period=="Uninitialized"]
                Chart item=Weather_Chart period=D refresh=30000 visibility=[Weather_Chart_Period==1]
                Chart item=Weather_Chart period=W refresh=30000 visibility=[Weather_Chart_Period==2]
            }
        }
    }
     
    Frame label="Lempos" {
    Text label="MiLight1" icon="light-on" {    
    Frame label="jungikliai"      {
        Switch         item=All_RGBW    label="Koridorius"
        Slider         item=Light_Koridorius_RGBW      label="Koridorius_dimer" 
    }
    }
    }

I’m sure that the mistake will be a newbie mistake…

Thanks in advance

Did you setup all items in .items-File?

intruder82 · December 30, 2015, 6:54am

Hi Udo,

thanks for the reply.
Yes all the items that are used in sitemap are declared in .items file…

And why am I getting different responses when I enter it from browser and from mobile app…

Udo_Hartmann · December 30, 2015, 6:01pm

Could be there is a bracket } missing at end of .sitemap.

Do you use the openHAB Designer for editing?

intruder82 · January 5, 2016, 7:26am

Yes I do use the openHAB Designer, no errors from that side, does openHAB Designer ignore the } brackets? I’ll try to check this today.
