Setting diagram measurement unit to Pixel not working [message #222307]

Hi everybody,
I'm using GMF build 2.2.0m5(2009/02/09),and I found a problem, please help
take a look if it is a GMF probelm or I did something wrong.

I define my own diagram and set the diagram measurement unit to "Pixel" in
the GMF GenModel, but when I create my own diagram editor, in the model
file, I find the unit is set to "Himetric":
<notation:Diagram xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:notation="http://www.eclipse.org/gmf/runtime/1.0.2/notation"
type="UEP" name="sup.model_diagram" measurementUnit="Himetric">

If I open an editor whose measurementUnit is "Pixel", after opening the
editor, the unit is automatically changed to "Himetric"

I tried to do some debugging, and find in the class
org.eclipse.gmf.runtime.notation.impl.DiagramImpl, when set this unit with
the method setMeasurementUnit(MeasurementUnit newMeasurementUnit), the
eFlags is set by eFlags |= MEASUREMENT_UNIT_ESETFLAG;
But when get the unit, it is done by return
MEASUREMENT_UNIT_EFLAG_VALUES[(eFlags & MEASUREMENT_UNIT_EFLAG) >>>
MEASUREMENT_UNIT_EFLAG_OFFSET];

Here I think MEASUREMENT_UNIT_ESETFLAG and MEASUREMENT_UNIT_EFLAG should
have the same offset, and that should be MEASUREMENT_UNIT_EFLAG_OFFSET.
But actually, MEASUREMENT_UNIT_EFLAG_OFFSET is set to 11,
MEASUREMENT_UNIT_EFLAG is set to 1 << MEASUREMENT_UNIT_EFLAG_OFFSET,
MEASUREMENT_UNIT_ESETFLAG is set to 1 << 12

Can anybody help me on this? Thanks

Hello Haoyue,

Just switch to 2.2.0m5a(2009/02/12) or later build. It should help. 2.2.0m5a
build was announced in news://news.eclipse.org/gn1m0l$5c1$1@build.eclipse.org

You can get more details in bug 264438 (https://bugs.eclipse.org/bugs/show_bug.cgi?id=264438).

Best wishes,
Tanya.
