Incompatible type for NOT operator: nullable`1[system.boolean].

Hello, all

I am having a strange problem in consuming my PB.NET assebly in another PB.NET application.

I have a function InitializeComponent in the assebly, which returns boolean,

But when I try to use it in the following code:

//---------------------------

if not ln_guest_srv.InitializeComponent(gs_odbc) then

  return false

end if

//-------------------------

I get the following error:

Incompatible type for NOT operator: nullable`1[system.boolean].

Is there some definition problem in the assembly?
