Illegal Characters in Path Exception in Sitecore Preview
Wed Sep 14 2011
Just filed a bug report with Sitecore Support. In case you are out there searching Google for the same exception, here’s the issue. This is Sitecore 6.4.1 rev. 110720.
One of my developers accidentally applied Layout Details to a template, instead of its Standard Values. This used to work, even though it is not a best practice. When opening items based on the template, most of the time he would get the error below. This seems to be due to WebEditRibbon.ConvertToJson not finding the Layout Details on the template, then calling the wrong method on XmlDocument (Load instead of LoadXml).
[ArgumentException: Illegal characters in path.] System.IO.Path.CheckInvalidPathChars(String path) +142 System.IO.Path.NormalizePath(String path, Boolean fullCheck, Int32 maxPathLength) +100 System.IO.Path.GetFullPath(String path) +187 System.Xml.XmlResolver.ResolveUri(Uri baseUri, String relativeUri) +131 System.Xml.XmlTextReaderImpl..ctor(String url, XmlNameTable nt) +135 System.Xml.XmlDocument.Load(String filename) +85 Sitecore.Web.UI.WebControls.WebEditRibbon.ConvertToJson(String layout) +210 Sitecore.Web.UI.WebControls.WebEditRibbon.Render(HtmlTextWriter output, Item item) +1268 Sitecore.Web.UI.WebControl.Render(HtmlTextWriter output) +387 System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) +246 System.Web.UI.HtmlControls.HtmlForm.RenderChildren(HtmlTextWriter writer) +315 System.Web.UI.HtmlControls.HtmlContainerControl.Render(HtmlTextWriter writer) +48 System.Web.UI.Control.RenderControlInternal(HtmlTextWriter writer, ControlAdapter adapter) +11363410 System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) +246 System.Web.UI.Page.Render(HtmlTextWriter writer) +40 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +5290
The solution is simply to apply the layout details to the Standard Values, instead of the Template itself.
