There seems to be a problem with using custom CSS in the TinyMCE editor in EPiServer 6 R2.

For the life of me I cannot get the editor to reference my stylesheet.

I have tried the following three approaches:

1. Create a dynamic property called UIEditorCSSPaths.

2. Set the path in the admin system settings.

3. Create a TinyMCE plugin in my project like so:

[TinyMCEPluginNonVisualAttribute(
        AlwaysEnabled = true,
        PlugInName = "TinyMceConfig",
        DisplayName = "TinyMCE textstyles ",
        Description = "Set custom text styles in Tiny MCE editor",
        EditorInitConfigurationOptions = @"{
        paste_auto_cleanup_on_paste : true,
        content_css : ""MYPATH/Editor.css""
      }"
    )]

    public class TinyMceConfig
    {
    }

None of these approaches have worked.

Has anyone managed to get the editor to reference a custom CSS file?

Thanks,

Robert
