I am trying out the Evaluation of the JGo package and working through
the documentation. I am at the point where I am adding sample
JGoNodes to the palette (pg 78 in the JGo User Guide). When I run
the modified code (which I verified is being compiled and run) and the
setShowSampleItems() is commented out but, the new nodes are not being
shown. They have been added and I am calling the layoutItems()
method as documented. Is there something else I need to do, to
force them to be shown? Everything else up to this point is
working as documented…


Apparently the problem was caused by a minor oversight in Swing programming in his application.
