What happened to CompositeSymbol after flex api 3.0?

AntonNovichikhin — Sun, 12 Dec 2021 00:46:18 GMT

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?

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.

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?

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.

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