Edited Unassigned: InvalidOperaitionException with ClientPropertyName [27986]

Hello,

For about a year, we are using ajax server control that inherit from other ajaxcontroltoolkit controls, like explained in this tutorial :
http://code.tutsplus.com/tutorials/asp-net-ajax-server-controls-with-client-side-functionality--net-26166
The new version of ajaxcontroltoolkit (v15.1.4) seems has a bug and i’m receving a messsage « Sys.InvalidOperationException: 'assemblyControl' is not a property or an existing field. »
C#
[Browsable(false)]
[ExtenderControlProperty]
[ClientPropertyName("assemblyControl")]
public string AssemblyControl
{
get
{ return _assembly; }
set { _assembly = value; }
}

The problem was intended to be solved, like explained here : https://ajaxcontroltoolkit.codeplex.com/workitem/27969 (if it's really the same issue), but the bug is still in place.

Any idea ?


Thank in advance.
