Error (#2148) Loading XML with Flex2

I was running through a simple tutorial for loading XML into Flex and displaying it in a DataGrid when I got the following error:

[RPC Fault faultString=”Error #2148: SWF file file:///C:/Documents and Settings/…/My Documents/xmlParsing/bin/xmlParsing.swf cannot access local resource Blades.xml. Only local-with-filesystem and trusted local SWF files may access local resources.” faultCode=”InvokeFailed” faultDetail=”null”]

If I go into the bin folder and launch the SWF directly then everything loads and works correctly. That right off is a tip that it’s probably a security issue. Sure enough. With a little research I found it.

  • In the Navigator panel Right-click and select Properties
  • In the lefNav select Flex Compiler
  • In the Additional compiler arguments: field add the following argument: -use-network=false

So my arguments read: -locale en_US -use-network=false

It would seem that this setting has to be made for each project.

Stupid security settings. 🙂

When I Googled this problem I only got three hits back. My guess is that this will be a common problem so it wouldn’t hurt for others to duplicate this solution to make it easier for others to find.

The problem is that with


you can no more get access to Internet resources such as normal Web pages. This is really annoying. Is there a way to avoid that?
