Probably means that the CB's width is also NaN and got that way due to some funky layout logic somewhere.

I have a programatically defined ComboBox with a bound dataProvider. The dataProvider starts out as an empty ArrayCollection. A RPC returns values and populates the ArrayCollection on the bound object. In this case, there is 1 element in the ArrayCollection which is a string. When the bound object is populated, I get this error: ArgumentError: Error #2004: One of the parameters is invalid. at flash.display::Graphics/drawRoundRect() at mx.skins::ProgrammaticSkin/drawRoundRect() [E:\dev\3.0.x\frameworks\projects\framework\src\mx\skins\ProgrammaticS kin.as:745] at mx.skins.halo::ButtonSkin/updateDisplayList() [E:\dev\3.0.x\frameworks\projects\framework\src\mx\skins\halo\ButtonSk in.as:217] ... Debuging, I find that ProgrammaticSkin is trying to call: drawRoundRect(x=0,y=0,width=NaN,height=24,ellipseSize=8,ellipseSize=8) Any ideas on what is going on here? For the record, my code defining the ComboBox and the binding is: textSelect = new ComboBox(); textSelect.percentWidth = 50; textSelect.dataProvider = param.possibleValues; BindingUtils.bindProperty (textSelect,"dataProvider",param,"possibleValues"); BindingUtils.bindProperty(param,"value",textSelect,"selectedItem"); paramJob = new SASGetPVJob(paramJob,null,param,null); paramJob.run(); //Makes the RPC call to get possible values for the param item.addChild(textSelect); //item is the FormItem tForm.addChild(item); //tForm is the Form
