Hi there,

i have a problem with a String Item to update.

I have a Item like this: String windstaerke\_max "max " (wetter)

And I try to update on this way:  
windstaerke\_max.postUpdate("Inhalt: "+tmp\_str.toString)  
I can see the right value in the debug log. But I get no value to display?

What’s wrong?

All the best  
Knut

Try changing your item to

`String windstaerke_max "max [%s]" (wetter)`

Hi,

I did it. Unfortunately without success. :o(  
This is my Item now: String windstaerke\_max “max [%s]” (wetter)  
And this is the log entry:  
09:20:23.221 [INFO] [runtime.busevents :26] - windstaerke\_max state updated to 4.8 km/h (08:56)

But I get no result in my frontend.

Hello,

I resolved the problem. I don’t know why but I rewrite the entry in the sitemap with the same content. Now it is running. (why? :o) )
