Alex, Ed,
I also thought so, but seems that's not the reason. Specially when I
happens no matter where the resource come from: CDO or XMI. Furthermore,
all the values of the XML appear correctly in the properties view. It's
just a problem on how the diagram is showing them. And even more weird:
if I double click on any box in the diagram to edit the name, an editing
box appears with the correct value!!
I've tried a clean installation of eclipse, with latest integration
builds of most of the typical plugins (EMF, transaction, validation,
ocl, GMF, GEF...). I deleted deleted and regenerated the diagram editor
code. Even regenerated the .gmfgen. Even regenerated the model itself,
extending EObject and extending CDOObject, both with the same result.
I'll keep investigating...

Alex,
thanks for your feedback. I've spent a lot of time on this, but finally
found the problem. I hacked variables value in the code, and suddenly
everything started to show up fine!
The problem is in org.eclipse.draw2d.text.TextFlow.paintText(Graphics g,
String draw, int x, int y, int bidiLevel)
protected void paintText(Graphics g, String draw, int x, int y, int
bidiLevel) {
if (bidiLevel == -1) {
g.drawString(draw, x, y);
} else {
TextLayout tl = FlowUtilities.getTextLayout();
if (isMirrored())
tl.setOrientation(SWT.RIGHT_TO_LEFT);
tl.setFont(g.getFont());
tl.setText(draw);
g.drawTextLayout(tl, x, y);
}
}
And the responsible is the "bidiLevel".
While debugging, I realized that the value of the text was never
scrambled, but rather just drawn incorrectly. This argument was always
set to "-1". I hacked it to be set always to something different to
"-1", and it worked!
I suspected from it yesterday while trying different eclipse
installations, GMF crashed with problems related with com.ibm.icu, the
owner of the "BidiProcessor".
Anyway. Do you have a clue why I'm receiving "-1" in the BidiLevel?
