What steps will reproduce the problem?

  1. Install flashbuilder 4.0.0
  2. Follow directions to have Flex Lib
  3. Have an empty application with only an HSlider

What is the expected output? What do you see instead? I should be seeing an hslider.

Instead, I'm getting an error: TypeError: Error #1009: Cannot access a property or method of a null object reference. at flexlib.baseClasses::SliderBase/getComponentBounds()[/Users/groumly/Development/workspace-3.5-flex4/FlexLib/src/flexlib/baseClasses/SliderBase.as:1845] at flexlib.baseClasses::SliderBase/measure()[/Users/groumly/Development/workspace-3.5-flex4/FlexLib/src/flexlib/baseClasses/SliderBase.as:1505] at mx.core::UIComponent/measureSizes()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8042] at mx.core::UIComponent/validateSize()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\core\UIComponent.as:7966] at mx.managers::LayoutManager/validateSize()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\LayoutManager.as:617] at mx.managers::LayoutManager/doPhasedInstantiation()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\LayoutManager.as:709] at mx.managers::LayoutManager/doPhasedInstantiationCallback()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\LayoutManager.as:1072]

What version of the product are you using? On what operating system? I have flash 4.0.0. I'm using FlexLib 2.5 for Flex4 (though the flex 3 one provided the same problem.

Please provide any additional information below. This seems to only be a problem for HSlider... TreeGrid came up fine.

I forgot to mention I'm using Windows 7.

I have it working in Flex Builder 3. Flash Builder 4 on Windows 7 and XP doesn't work.

I have the same problem here using Flash Builder 4 on XP. Tried to compile with the flexlib Flex 3 lib, but got the same error.

You have to assign a track skin to get around this problem.

It doesn't seem to work for me setting the trackSkin as a mxml attribute. I achieved to make this component work (with Flex sdk 4.1) setting the trackSkin and thumbSkin values in css :

MySlider {

trackSkin: ClassReference("mx.skins.spark.SliderTrackSkin");
thumbSkin: ClassReference("mx.skins.spark.SliderThumbSkin");

}

Great, this post helped! Only thing is that I also had to add trackHighlightSkin to my css to get it to work

flexlib|HSlider {
trackSkin: ClassReference("mx.skins.spark.SliderTrackSkin"); thumbSkin: ClassReference("mx.skins.spark.SliderThumbSkin"); trackHighlightSkin: ClassReference("mx.skins.spark.SliderTrackHighlightSkin"); }
