Hi Gonzalo
I did some tests on ./mcs/class/System.Web/System.Web.UI/Control.cs and
noticed if the TemplateSourceDirectory is empty, I get the crash.
[EditorBrowsable (EditorBrowsableState.Advanced)]
[Browsable (false)]
[DesignerSerializationVisibility
(DesignerSerializationVisibility.Hidden)]
public string AppRelativeTemplateSourceDirectory {
get {
if (_appRelativeTemplateSourceDirectory != null)
return _appRelativeTemplateSourceDirectory;
string tempSrcDir = null;
TemplateControl templateControl = TemplateControl;
if (templateControl != null) {
string templateVirtualPath =
templateControl.AppRelativeVirtualPath;
if (!String.IsNullOrEmpty (templateVirtualPath))
tempSrcDir =
VirtualPathUtility.GetDirectory (templateVirtualPath, false);
}
_appRelativeTemplateSourceDirectory = (tempSrcDir !=
null) ? tempSrcDir : VirtualPathUtility.ToAppRelative
(TemplateSourceDirectory==string.Empty?"/":TemplateSourceDirectory);
return _appRelativeTemplateSourceDirectory;
}
[EditorBrowsable (EditorBrowsableState.Never)]
set {
_appRelativeTemplateSourceDirectory = value;
_templateSourceDirectory = null;
}
}
So, i added this line, which is probably not ok, but it works now. Im
not sure what the TemplateSourceDirectory should be in this case. Do you
have a suggestion?
Cheers
Peter
