Hi, Thanks Harbs for that.
I must have something wrong with my set up as I get this when I try to compile: [INFO] Executing COMPC in tool group FlexJS with args: [-load-config=/Users/justinmclean/flex-asjs/frameworks/projects/HTML/target/compile-js-config.xml, -js-output-type=FLEXJS, -compiler.strict-xml=true] /Users/justinmclean/flex-asjs/frameworks/projects/HTML/src/main/flex/org/apache/flex/html/supportClasses/HScrollingViewport.as(56): col: 55 Access of possibly undefined property overflowX through a reference with static type CSSStyleDeclaration. (contentView.element as HTMLElement).style.overflowX = 'auto’; > > (contentView.element as HTMLElement).style.overflow = ''; > (contentView.element as HTMLElement).style.overflowX = 'auto'; > (contentView.element as HTMLElement).style.overflowY = 'hidden’; Not really an issue here - but I believe overflow = “hidden” then overflowX = ‘auto’ is more browser compatible. Thanks, Justin
