[Celerity-users] Silencing a specific SEVERE warning from Dojo

[Ashley Moran]

Hi

I'm being bugged lately by a warning from the Dojo library.  The  
following script is enough to trigger it, but also generates a few  
unrelated warnings:


   require 'rubygems'

   gem 'jarib-celerity'
   require 'celerity'

   browser = Celerity::Browser.new
   browser.goto("http://dojotoolkit.org/")


The one that is causing a problem is:

SEVERE: runtimeError: message=[document.execCommand(): invalid command  
'BackgroundImageCache'] sourceName=[http://dojotoolkit.org/sites/all/modules/dojo/dtk_build/dojo/dojo.js 
] line=[20] lineSource=[null] lineOffset=[0]

This is caused by the following code in Dojo (if you use  
dojo.js.uncompressed.js):

   try{
     document.execCommand("BackgroundImageCache", false, true);
   }catch(e){
     // sane browsers don't have cache "issues"
   }

Now, the whole thing is wrapped in an exception block, which means I  
wouldn't expect to see any error reporting.  (Clearly, it's logging  
anyway.)  The implication is, I guess, that HtmlUnit is not "sane".

Is there a way round this?  Because of the unfortunate SEVERE log  
level, we've been forced to disable all JavaScript error reporting, or  
suffer this several hundred times during a Cucumber feature run.

Workarounds/other feedback much appreciated.

Thanks
Ashley
