    • Type: Bug
    • Status: Closed
    • Priority: Major
    • Resolution: Not A Problem
    • Affects Version/s: Adobe Flex SDK 4.0 (Release)
    • Fix Version/s: None
    • Component/s: Spark: DropDownList
    • Labels:
    • Environment:
      Affected OS(s): All OS Platforms
      Affected OS(s): All OS Platforms
      Browser: Firefox 3.x
      Language Found: English


      Steps to reproduce:
      1. add a spark DropDownList to mx:Module
      2. in <s:Application add an mx:ModuleLoader url=""
      3. add module via byte array
      theSwf = event.message.body as ByteArray;
      theModuleLoader.loadModule(null, theSwf);

      Actual Results:
      get rutime error cannot find skin

      Expected Results:
      no runtime error, had no problem from nightly's in the 14xxx but started happening after that, found ugly work around, but now that 4 released this should be fixed

      Workaround (if any):
      extend DropDownList and add skin in contstuctor, eg ** note also had to remove scroller, same skin issue at runtime

      public class BugFixDropDownList extends DropDownList {
      public function BugFixDropDownList()

      { super(); setStyle("skinClass", Class(BugFixDropDownListSkin)); }
