drawinginfo.renderer.symbol.source...

Question

At beta, update 3, I was doing with success...
item.legendImage = o.drawingInfo.renderer.symbol.source;

to get the image source url string for point features.

Now the "source" property returns a ByteArray and crashes the app.

I was using the string to populate a custom Item object as show above. Then using the item in a List object for a custom legend/TOC.

How can I do the same thing now with a ByteArray?  I notice that what used to be a url with PNG file is now like this:
"http://hiatus/ArcGIS/rest/services/dev/EM_Assets/MapServer/32/images/C8D05CC1"

Anyway, I'd just like to be able to use the drawinginfo property (or whatever property would have the image path for point features) for the point symbol.

Thanks much.

You can just add the UIComponent returned by createSwatch() to a container to view a representation of the symbol.

You could call http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/symbols/Symbol.html#createSwatch() or pass the ByteArray to the Flex Image component as it's source.

Thanks Dasa,
I've got the ByteArray working... what would be an example usage of the createSwatch method?  How would I use the resulting object as the source from an Image?
