Я создаю функцию SharePoint, и в моем FeatureReceiver
я пытаюсь добавить SPWebConfigModification
.Я следовал подходу, описанному в этом сообщении в блоге.
Вот фрагмент моего получателя функций:
public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
var webApp = (SPWebApplication)properties.Feature.Parent;
var debugMode = new SPWebConfigModification
{
Path = "configuration/system.web/customErrors",
Name = "mode",
Value = "Off",
Sequence = 0,
Type = SPWebConfigModification.SPWebConfigModificationType.EnsureAttribute,
Owner = "MyWebConfigMods"
};
webApp.WebConfigModifications.Add(debugMode); // <------ Error is thrown at this line
webApp.WebService.ApplyWebConfigModifications();
webApp.Update();
}
Вот трассировка стекаошибка, видимая в средстве просмотра ULS SharePoint:

Где-то во время обновления указывается пустой путь в выражении XPath
.Это не в моей особенности.Есть идеи?
