a deprecated class

[nhhockeyplayer nashua]

Folks,

I have some code using 

ValidationDecorator decorator = new DefaultValidationDecorator(environment,
            assetSource.getExpandedAsset("${tapestry.spacer-image}"), 
markupWriter);

DefaultValidationDecorator.class

But its gone from the t-5.4 jar

Can someone suggest a course of action?

Best regards 
and thanks... KEN
