Re: Configuration setup

	Hi, Daniel.

	Is it safe to assume that template loader changing and auto-imports and
shared variable definitions should be executed once per Configuration
instance?
	I'm "reconfiguring" the same Configuration instance, with the *same*
values, more than once. I intend to rework this code.


       def loaders = [stringLoader, oldLoader]
       def loader = new MultiTemplateLoader(loaders as TemplateLoader[])
       configuration.setTemplateLoader(loader)

       autoImport.each {
	configuration.addAutoImport(it.key, it.value)
       }

       if (sharedVariables != null) {
	def replacedSharedVars = new HashSet();
	sharedVariables.entrySet().each {
	  entry ->
	    def sharedVar = configuration.getSharedVariable(entry.key)
	    if (sharedVar != entry.value) {	
	      replacedSharedVars << entry.key
	      configuration.setSharedVariable(entry.key, entry.value)
	    }
	}
       }
     }



	Thanks.

	Best regards,

		Daniel.
