[GoogleCodeExporter]

What steps will reproduce the problem?

xxx.items
---------
Number WPHeizkurvenabweichung   "WP Heizkurvenabweichung"       <smiley>        
(Waermepumpe)   { exec=">[50:/usr/local/luxtronik/lux4openhab.pl heizkurve 50] 
>[-5:/usr/local/luxtronik/lux4openhab.pl heizkurve -5] 
<[/usr/local/luxtronik/lux4openhab.pl heizkurve:60000:REGEX((.*?))]" }

xxx.sitemap
------------
Selection item=WPHeizkurvenabweichung  label="Heizkurvenabweichung" 
mappings=[50='5°C', -5='-0,5°C' ]

=> The selection will not show up on the Gui. Trying to access it through the 
GUI results in the following runtime error:

21:30:20.042 WARN  o.e.j.servlet.ServletHandler[:553] - /openhab.app
java.lang.NullPointerException: null
        at java.lang.String.replace(String.java:2228)

What version of the product are you using? On what operating system?
Openhab 1.2 on Debian 6.0.5
