Hey,

"Set Image Properties" results in a "Value cannot be null"?

My codebehind radeditor-setup looks like:
    reText.DialogParameters.Clear();
    ParameterCollection imageArguments = new ParameterCollection();
    imageArguments.Add(new Parameter("ThumbSuffix", reText.ThumbSuffix));
    imageArguments.Add(new Parameter("MaxImageSize", reText.MaxImageSize.ToString()));
    imageArguments.Add(new Parameter("AllowThumbGeneration",   reText.AllowThumbGeneration.ToString()));
    imageArguments.Add(new Parameter("SiteUrl", SPEncode.UrlEncode(sURL)));
    imageArguments.Add(new Parameter("WebUrl", SPEncode.UrlEncode(sRelativeURL)));
    reText.DialogParameters.Add("SharePoint/ImageManager", imageArguments);

Hi Elton

    foreach(Parameter p in imageArguments)
    {
     if (p.Value==null)
      Response.Write(HttpUtility.HtmlEncode(p.Name)+" = null<br>");
     else
      Response.Write(HttpUtility.HtmlEncode(p.Name)+" = "+HttpUtility.HtmlEncode(p.Value)+"<br>");
    }

Results in...

ThumbSuffix = Thumbnail
MaxImageSize = 204800
AllowThumbGeneration = False
SiteUrl = http%3A%2F%2Fdomaintest%2FC18%2FPictureArea
WebUrl = %2FC18%2FPictureArea

So no null values present in the collection.
