New issue 1028 by [hidden email]: the transformation block is not  
called correctly
http://code.google.com/p/moose-technology/issues/detail?id=1028

When using a transmission with a transformation block, the transformation  
block is not called when creating the presentations. The code bellow will  
show a list from 1 to 10 instead of one from 1 to 20:

browser := GLMTabulator new.
browser row: #row.
browser transmit
        to: #row;
        transformed: [ :anInt |  anInt+10 ];
        andShow: [ :aComposite :anInt |
                aComposite list
                        display: [ 1 to: anInt ] ].
browser openOn: 10.

The transformation block is only called when populating the port, which  
happens after the presentation was created.

This can be fixed by modifying GLMPresentStrategy>>presentations to use the  
transformation, but the the block will be called two times.
