I did this, cut out the relevant part of gui.stetic and placed it in the
new gui.stetic. All seemed ok the UI builder recognised the code and
displayed the widget ok. Asked me if I wanted to attach to an existing
class or generate a new class. Options to attach to,  didnt include the
class I wanted so I generated a new class, but now this had an empty
build function. I then copied the existing build function and pasted it
in the required place and compiled. But I keep getting an error  see below

[Task:File=/home/alan/C# development/OTPaths
1.5/OTPaths/gtk-gui/OTPaths.PathChoice.cs, Line=27, Column=20,
Type=Error, Priority=Normal, Description=The type or namespace name
`BinContainer' does not exist in the namespace `Stetic'. Are you missing
an assembly reference?(CS0234)]

This is even though auto completion on Stetic shows BinContainer option
when editing auto generated code line highlighted below

 protected virtual void Build() {
            Stetic.Gui.Initialize(this);
            // Widget GenTemplates.PathChoice
            Stetic.BinContainer.Attach(this);  
************************* this causes error
            this.Name = "OTPaths.PathChoice";
             ...

If I comment this line out compiles with no error. Can I safely leave
this line out (I guess not) . What have I done wrong / missed ?
