Do you have a compiler warning such as "Cannot bind to ButtonColor" because presenter is not EventDispatcher ?
That could be the reason. Other than that, the code seems good. Also, did you try having only the ButtonColor prop [Bindable], not the whole class?

Hi Martin Let's have another go at displaying the code: I have declared my presenter Class as [Bindable]. In my presenter I have a property as follows: internal var _ButtonColour:uint = 0x000000; public function get ButtonColour():uint { return _ButtonColour; } public function set ButtonColour(value:uint):void { _ButtonColour = value; } I have a Switch statement to change the value depending on the value of another property which may change: private function setButtonColour():void { trace("setButtonColour called. ButtonColour = " + String(ButtonColour)); switch(LessonType) { case "purpose": ButtonColour = 0x24c07f; break; case "components": ButtonColour = 0x53c7c7; break; case "locate": ButtonColour = 0x88b9ff; break; case "process": ButtonColour = 0xab8ff2; break; case "safetycase": ButtonColour = 0xe380fe; break; case "interlocks": ButtonColour = 0xf187c5; break; case "safetyfeatures": ButtonColour = 0xfe6856; break; case "interrelation": ButtonColour = 0xff8233; break; case "opex": ButtonColour = 0xf99c38; break; case "other": ButtonColour = 0xf5d846; break; default: ButtonColour = 0x7ab73e; break; } trace("ButtonColour set to " + String(ButtonColour)); } In my mxml file I have defined a Rectangle as follows: <s:Graphic xmlns:fx="http://ns.adobe.com/mxml/2009"; xmlns:s="library://ns.adobe.com/flex/spark" xmlns:presenters="presenters.*"> <fx:Declarations> <presenters:SliderView_Presenter id="presenter" /> </fx:Declarations> <s:Rect id="BtnColour" width="24" height="24" radiusX="12" radiusY="12"> <s:fill> <s:SolidColor color="{presenter.ButtonColour}" /> </s:fill> </s:Rect> </s:Graphic> To recap, my presenter class has the [Bindable] meta tag above the Class definition. My view includes an HSlider which sets the skinClass = SliderSkin. The SliderSkin skin class defines the Thumb button and sets its skinClass to SliderThumbSkin. In my SliderThumbSkin I want to bind the colour of an element in the button definition (a Rect with a Fill of solidColour) to a value in my presenter class. The presenter class would be instantiated by the hostComponent, the HSlider, so I'm wondering if I should access the property through this. Currently my colour property in the presenter is set its initial value and the button is set to this colour, when the colour value changes though the button does not get notified and does not change. Does that help?
