How to change the skin of the Combobox and DropDownList
Hi All:
Now, my project need to change the skin of the components at runtime, I used styleManager.loadStyleDeclarations(styleList.selectedItem["styleUrl"]) to change the skin. But the spark.components.supportClasses.DropDownListBase throw a error. My Adobe AIR SDK version is 3.7. Details are as follows:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at spark.components.supportClasses::DropDownController/set openButton()[E:\dev\4.y\frameworks\projects\spark\src\spark\components\supportClasses\DropDownController.as:100]

Hi,
Try switching to an Apache Flex SDK. Your issue should be fixed in 4.9
and later.
