I noticed in the Logic example that as text is entered into the Label
textflow, the figure resizes to "best fit" the new text. Can someone
point me to where in the code this is being accomplished?

That makes sense. I copied the logic example to create my node figure,
which is very similar in appearance. But even with the StackLayout code
from logic editor, I'm not seeing the behavior.
Is there an edit policy I should check for that might be preventing the
resize from happening? The parent figure (the node) is in fact
resizable by the user.

OK that also makes sense. My DirectEditPolicy looks just like the
example.. But it doesn't seem to cause the expected behavior. Even
while I am typing text into the flow, it simply scrolls to accommodate
more text, instead of resizing.
Figure code here:
public ScenarioNodeFigure()
{
setBorder(new LineBorder(2));
flowPage = new FlowPage();
flowPage.setOpaque(true);
flowPage.setBackgroundColor(ColorConstants.white);
flowPage.setBorder(new MarginBorder(3));
textFlow = new TextFlow();
textFlow.setLayoutManager(new ParagraphTextLayout(textFlow,
ParagraphTextLayout.WORD_WRAP_SOFT));
textFlow.setOpaque(false);
flowPage.add(textFlow);
flowPage.setBackgroundColor(ColorConstants.white);
setLayoutManager(new StackLayout());
add(flowPage);
incomingConnectionAnchor = new ScenarioLinkAnchor(this,true);
outgoingConnectionAnchor = new ScenarioLinkAnchor(this,false);
}
....
public void setText(String newText) {
textFlow.setText(newText);
}

Does anyone else have any further suggestions or help regarding this

Thanks for the help Alex. Turns out I was looking in the wrong place.
In refreshVisuals for the node edit part, I was setting a layout
constraint on the node figure based on the dimensions stored in the
node's model object. Removing this constraint allowed my figure to
resize at will.
