Build in FlashDevelop

[AaronPerry]

I want to create a custom widget for the flex viewer. I have installed FlashDevelop 4.3.0, imported the ArcGIS Viewer for Flex source, and the API swc. I'm having the same problem as described in this post, but I still don't understand how to resolve the config file issue.  When I build the project, FlashDevelop kicks off the debug player, and I get the following message.  Nothing else happens.  Can anyone help me figure out how to fix this config.xml problem? The error message follows, and I've attached a screenshot.

Could not find config.xml

I haven't heard of anyone building widgets successfully without using Adobe Flash Builder, unfortunately. I'd love to be proven wrong!

In the case of widgets provided as source, the config.xml file should be provided in the same folder as the <widget>.mxml file - you'll want to make whatever necessary edits to the config.xml file, then copy it to the same destination folder as your widget's .swf file.  That /should/ solve the specific problem of the config.xml file not being found.

Good luck with your coding!
