I have encompassed using v flex 4 vgroup to set background image. Additional than image was not display. Subsequent to upgrading a project from Flex4 Beta1 to Beta2, I have originated that the background-image style is no longer supported on Halo apparatus. Additional than this is not using a spark skin, immediately a standard Halo apparatus. It's not too hard to copy the defaulting skin and add a background to it. On the other hand, you be supposed to in addition be capable to utilize the previous Halo skin to get the backgroundImage maintain, if that's what you prefer. I believe you desire to tell your VBox to utilize mx.skins.halo.HaloBorder.
