after v2.5 upgrade: ???Error #2124: Loaded file is an unknown type.???

[AshleyOwens]

After upgrading from ArcGIS Viewer 2.1 to 2.5, I get error ???Error #2124: Loaded file is an unknown type.??? for any HTML file I attempt to load (such as help or legend files). Has anyone else experienced this?

Thank you,
Ashley

Ashley,

   What do you mean?... When you load HTML files in what?

[AshleyOwens]

Sorry...when I'm requesting them inside my Flex Viewer application, such as clicking on a menu item for our legend.

Ashley,

   I just need a little more detail... When you say menu Item you mean what exactly?

In our config XML file, we have

<widgetgroup label="Help" icon="assets/images/i_help.png">
    <widget label="Help"   left="100" top="90" 
                icon="assets/images/i_help.png"
                config="Link"
                url="assets/help/TIGERHelp1.html"/>
    <widget label="Legend"   left="100" top="90" 
                icon="assets/images/i_resources.png"
                config="Link"
                url="assets/legend/legend.html"/>
    <widget label="Contact"   left="100" top="90" 
                icon="assets/images/icon_contact.png"
                config="Link"
                url="cmt.html"/>
</widgetgroup> 

Clicking any of these causes "Error #2124: Loaded file is an unknown type." I can load each of these HTML files if I go to the URL directly, and not through our application.

Ashley,

   That's what I was afraid of... And you are saying this exact setup worked in 2.1?... You need to look at the link widget:

What you are attempting to do will not work...
