What happened to CompositeSymbol after flex api 3.0?

[AntonNovichikhin]

In the API version 3.0 I could create fillsymbol with markers at vertexes.
e.g.

<esri:CompositeSymbol id="fill">
[INDENT]<esri:SimpleFillSymbol alpha="0.2" color="0x000000" style="solid">
[INDENT]<esri:outline>
[INDENT]<esri:SimpleLineSymbol width="3" color="0x00FFCC"/>[/INDENT]
</esri:outline>[/INDENT]    
</esri:SimpleFillSymbol>
<esri:SimpleMarkerSymbol color="0x00EEBB" size="12" style="circle"/>[/INDENT]
</esri:CompositeSymbol>

[ATTACH=CONFIG]25328[/ATTACH]
after changing the library to 3.3 version application when I try to add a polygon graphics with such a symbol to a graphics layer application fails with the error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

Composite line symbol just ignores the marker and draws without it, posting to console, but app is still alive:

Any ideas?

I had a similiar problem when trying to pass a CompositeSymbol that contained a MarkerSymbol to a polygon graphics, almost like the polygon does not know what to do with the MarkerSymbol because that's for point graphics and it is a polygon graphic.

Are you setting the Mappoints manually like in Roberts example, or are you just pulling the graphics directly from a layer?

[AntonNovichikhin]

almost like the polygon does not know what to do with the MarkerSymbol because that's for point graphics and it is a polygon graphic.

flex documentation says that it should work similar to Cartographic Representations in ArcMap when your are able to symbolize elements of feature (vertices, outline, fill) with a symbol matched to their actual geometry

Are you setting the Mappoints manually like in Roberts example, or are you just pulling the graphics directly from a layer?

no. I'm getting a response from Identify or Find tasks and then add graphics to graphics layer.

Anton,
   Your issue must lie somewhere else in your code as this works fine for me. Here is a sample that does what you are attempting using the 3.3 API.

thanks for the test. i'll try to inspect whole graphic generation process in code.
