Hi,

I finally got mod_manage to load fine in FreeSWITCH on centos but now when I
copied a .net dll that I built and runs on windows to the /mod/managed
folder it loads fine on freeswitch startup but when try calling it (it's a
AppPlugin) from the dialplan using <action application="managed"
data="NameOfClass"/> I get these errors.


2010-09-01 00:21:23.303236 [ERR] switch_cpp.cpp:1177 Exception in
Run(NameOfClass): System.NullReferenceException: Object reference not set to
an instance of an object

Anyone have any idea what is the problem?

Thanks.
