Help with Flex ItemRenderer Datagrid Error #2148:

Asked by: Joel_Sisko

Dear Experts,

I am having problems using itemrenderer for my datagrid. I am able to render the data using the linkbutton, when I click on the link I get an error:

SecurityError: Error #2148: SWF file http://localhost/Recorder/bin-debug/Recorder.swf cannot access local resource file:///C:/Test/My%20Curse.mp3. Only local-with-filesystem and trusted local SWF files may access local resources.
      at global/flash.net::navigateToURL()
      at LinkItemRenderer/handleClick()[C:\wamp\www\Recorder\src\LinkItemRenderer.mxml:19]
      at LinkItemRenderer/___LinkItemRenderer_LinkButton1_click()[C:\wamp\www\Recorder\src\LinkItemRenderer.mxml:6]

The link location works when I paste into my browser directly, so the path is correct. I have a cross-domain file inplace and have set the Flash player to Globally trust "C:\"

Any ideas to what the issue is?

Thanks,

Joel

you are trying to access a file on your local machine from a web server (localhost) which is not possible. The file should sit on you server (albeit localhost) and the link should point there.

Well in my test setup everything is local.

So the goal would be that the file location (which is used to create the link) would be a mapped drive location such as F:/somefilename.ext

To clarify, I get the same security error if its my mapped drive as well.

Like i said... put the mp3 in the same folder as the swf to test it. The URL to the file should be relative and not absolute.

It would be a breach of security to be able to access files on a users harddrive. Think of the field day hackers would have just by getting people to view a web page.

Permissions work differently if the swf is running from the harddrive during dev and not from a server (which is what localhost is).

If you really need the file to remain in the C drive you would have to create a file there as a virtual directory via IIS.

Scooby_56,

Thanks for the help, the issue is that you assumed that this was turning to the web, it is an internal application.

The files that need to be accessed are mapped as the F:/ drive on each users system, whether I use C:/ or F:/ I get the same security violation.

Thoughts?

Joel

An internal application? then why is it running from locahost ?

As far as you web browser knows... localhost is a regular web page could be anywhere

A cross-domain file will do nothing as C:\\ is not a domain and does not use http protocols

SecurityError: Error #2148: SWF file http://localhost/Recorder/bin-debug/Recorder.swf cannot access local resource

//opening a file from localhost is not the same as directly opening the .swf via the file system.


Are you saying that you have accessed the file direcly via file system  (NOT localhost) and opened the .swf direcly - so browser address bar should read something like C:\inetpub..... (and NOT http://localhost.... etc)
