Hi all

I was hoping someone could explain the following...

I edited the Mindmap example to initialise the diagram with a simple topic..
by editing the MindmapDiagramEditorUtil#createInitialModel() method as
follows -

/**
* Create a new instance of domain element associated with canvas.
* 
* 
* @generated NOT
*/
private static org.eclipse.gmf.examples.mindmap.Map createInitialModel() {
org.eclipse.gmf.examples.mindmap.Map map = MindmapFactory.eINSTANCE
.createMap();
Topic topic = MindmapFactory.eINSTANCE.createTopic();

topic.setName("View Service Issue");
topic.setPercentComplete(50.0f);

map.getRootTopics().add(topic);

return map;
}

I noticed that when the resources were saved...
try {

modelResource

..save(org.eclipse.gmf.examples.mindmap.diagram.part.Mindmap DiagramEditorUtil

..getSaveOptions());

diagramResource

..save(org.eclipse.gmf.examples.mindmap.diagram.part.Mindmap DiagramEditorUtil

..getSaveOptions());

} catch (IOException e) {

MindmapDiagramEditorPlugin.getInstance().logError(

"Unable to store model and diagram resources", e); //$NON-NLS-1$

}

I had...

For the semantic ->

<?xml version="1.0" encoding="UTF-8"?>
<mindmap:map xmlns:mindmap="http://www.example.org/mindmap">
<rootTopics name="View Service Issue" percentComplete="50.0"/>
</mindmap:map>

and for the Notational ->

<?xml version="1.0" encoding="UTF-8"?>
<notation:Diagram xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:mindmap="http://www.example.org/mindmap"
xmlns:notation="http://www.eclipse.org/gmf/runtime/1.0.1/notation"
xmi:id="_W-UKEB3GEd2dfa0MC-ybSQ" type="Mindmap" name="default.mmd"
measurementUnit="Pixel">
<styles xmi:type="notation:DiagramStyle"
xmi:id="_W-UKER3GEd2dfa0MC-ybSQ"/>
<element xmi:type="mindmap:Map" href="default.mindmap#//@map"/>
</notation:Diagram>

But this seems wrong!!!... surely the notational should have a reference to
the topic... but it does not...

For example - A notational resource referencing the topic...

<?xml version="1.0" encoding="UTF-8"?>
<notation:Diagram xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:mindmap="http://www.example.org/mindmap"
xmlns:notation="http://www.eclipse.org/gmf/runtime/1.0.1/notation"
xmi:id="_W-UKEB3GEd2dfa0MC-ybSQ" type="Mindmap" name="default.mmd"
measurementUnit="Pixel">
<children xmi:type="notation:Node" xmi:id="_XhV-oB3GEd2dfa0MC-ybSQ"
type="2001">
<children xmi:type="notation:Node" xmi:id="_XhpgoB3GEd2dfa0MC-ybSQ"
type="5002"/>
<children xmi:type="notation:Node" xmi:id="_XhpgoR3GEd2dfa0MC-ybSQ"
type="7001">
<styles xmi:type="notation:DrawerStyle"
xmi:id="_Xhpgoh3GEd2dfa0MC-ybSQ"/>
<styles xmi:type="notation:SortingStyle"
xmi:id="_Xhpgox3GEd2dfa0MC-ybSQ"/>
<styles xmi:type="notation:FilteringStyle"
xmi:id="_XhpgpB3GEd2dfa0MC-ybSQ"/>
</children>
<styles xmi:type="notation:ShapeStyle"
xmi:id="_XhV-oR3GEd2dfa0MC-ybSQ"/>
<element xmi:type="mindmap:Topic"
href="default.mindmap#//@map/@rootTopics.0"/>
<layoutConstraint xmi:type="notation:Bounds"
xmi:id="_XhV-oh3GEd2dfa0MC-ybSQ"/>
</children>
<styles xmi:type="notation:DiagramStyle"
xmi:id="_W-UKER3GEd2dfa0MC-ybSQ"/>
<element xmi:type="mindmap:Map" href="default.mindmap#//@map"/>
</notation:Diagram>

So what gives? why does the ViewService not create the notational resource
fully? is it even supposed to...

Thanks in advance,
Kristian O'Connor

Hello Kristian O'Connor,

Corresponding topic element will be created automatically on diagram openning.
This diagram node will be marked as "transient" till the moment then user
modify it (move/set any view properties). Transient nodes should not be stored
in diagram files - they rather should be re-created on next diagram openning.
