[flexcoders] Runtime Error 1007 on a simple ProgressBar in Flex 4

2010-09-08 Thread PicSnapr 
This is such a simple code that compiles correctly, but I'm getting the error 
below when running it :(

TypeError: Error #1007: Instantiation attempted on a non-constructor.
   at 
mx.controls::ProgressBar/createChildren()[E:\dev\4.0.0\frameworks\pro 
jects\framework\src\mx\controls\ProgressBar.as:1110]
   at 
mx.core::UIComponent/initialize()[E:\dev\4.0.0\frameworks\projects\fr 
amework\src\mx\core\UIComponent.as:7250]
..

Here's the code that gives this error:

s:TitleWindow ...
.
.
 
 
s:controlBarContent
com:IconButton id=btnAdd toolTip=Add file(s) click=addFiles() 
icon={addIcon}
  skinClass=com.skins.IconButtonSkin width=20/
com:IconButton id=btnRemove toolTip=Remove file(s) click=removeFiles() 
icon={removeIcon}
  skinClass=com.skins.IconButtonSkin width=20/
mx:ProgressBar id=uploadProg labelPlacement=center width=100%/
com:IconButton id=btnCancel toolTip=Cancel upload icon={cancelIcon} 
click=onUploadCanceled()
  skinClass=com.skins.IconButtonSkin width=20/
com:IconButton label=Upload toolTip=Upload file(s) id=btnUpload 
icon={uploadIcon} click=uploadFiles()
  skinClass=com.skins.IconButtonSkin width=20/
com:IconButton id=btnView toolTip=Show/Hide file(s) click=changeView()
  icon.full={viewIconFull} icon.mini={viewIconMini}
  skinClass=com.skins.IconButtonSkin width=20/
/s:controlBarContent
/s:TitleWindow

If I remove the progressbar code from here, it runs fine. But with that one 
line, I get above error during runtime. With this line in, even the Design mode 
doesn't show-up in Flash Builder 4 :(

Any idea what could be the issue here?

PS: I've tried with the normal s:Button as well, before the skinned button 
component. So obviously those can't be the problem.

Default styles/skins for ProgressBar are missing.
