hello,
i have a problem with the RadTreeView for ASP.NET AJAX, in fact i got a Runtimeerror "Sys.ArgumentTypeException: The object with the type Telerik.Web.UI.RadTreeView can not be converted to the Type Telerik.Web.UI.RadTreeView" which seems strange to me.
This error is not reproducible, due to the fact that this error occours from time to time, when i do different operations on the website. for example i click ten times on a node and everything works fine, but on click later ther come the error.
the error occoured here:
Type.prototype.getBaseMethod = function Type$getBaseMethod(instance, name) {
/// <summary locid="M:J#Type.getBaseMethod" />
/// <param name="instance"></param>
/// <param name="name" type="String"></param>
/// <returns type="Function" mayBeNull="true"></returns>
var e = Function._validateParams(arguments, [
{name: "instance"},
{name: "name", type: String}
]);
if (e) throw e;
if (!this.isInstanceOfType(instance)) throw Error.argumentType('instance', Object.getType(instance), this);
var baseType = this.getBaseType();
if (baseType) {
var baseMethod = baseType.prototype[name];
return (baseMethod instanceof Function) ? baseMethod : null;
}
return null;
}
i hope you can help me!
best regards,
hannes
