firefox addon - How to use locale entity in js-code -

is possible value of entity

<!entity gatwayerror  "gateway error"> 

using javascript? reference them in xul file using

&gatewayerror; 

update: in ff-sidebar.xul within <page> have

<stringbundleset id="stringbundleset">     <stringbundle id="strings"                    src="chrome://myaddon/locale/de/sidebar.properties"/> </stringbundleset> 

in ff-sidebar.js on click:

var strbundle = document.getelementbyid("strings"); var localizedstring = strbundle.getstring("test"); 

this gives me following error

should not

var strbundle = document.getelementbyid("stringbundleset"); 

this gives me no error no result too.

basically neil posted there need (minus first paragraph rant :p )

here's example (basically digest neil's links):

your xul file:

<stringbundleset id="strbundles">     <stringbundle id="strings" src="chrome://yourextension/locale/something.properties"/> </stringbundleset> 

your something.properties (there define localized strings key=value). of course can have many files want/need:

something=some text localization something2=some more text 

your js file:

var strbundle = document.getelementbyid("strings"); var localizedstring = strbundle.getstring("something"); 

hope helps.
