I have some other components which are created like so in the workspace 'SDRButtonContainer newWithInteractors: (SDRFilterButtonBox new).'. This simply has a class initialise which takes a bunch of buttons. Odd thing is the events work here but 'SDRButtonContainer allInstances' still gives me nothing. I don't know therefore if these things are linked or separate problems.

There isn't enough information for me to figure out your main problem, but I think I know this one.
I bet that newWithInteractors: does not actually create an instance of SDRButtonContainer. You say it "ismply has a class initialise" so I think you are just storing the arguments in a variable of the class, but do not actually create an instance of the class. Note that SDRButtonContainer is a class, it is not itself a SDRButtonContainer. So, it has not instances and allInstances SHOULD return nothing.
In general, we will need more info to debug this. Give more code.
It is being created Ralph, but see below.

This sounds as if your object was garbage collected. If you want to keep your object, store it somewhere. Objects that aren't stored anywhere get cleaned up.
Well, it's the obvious reason, but I couldn't see why the behavior was different. Now I can. Some components set maps that create an indirect reference to the parent, others don't. The ones that don't do get garbage collected which up to now hasn't mattered because all calls in these components are to the morph not the parent. I think I will stop doing this stuff in the workspace and write a script to properly create and clean up the instances.
Thanks both for your help.
