Hi guys,
I'm quite new to GMF so you'll have to excuse my ignorance :)
I've been attempting (for quite a few weeks now) to create a Use-case
Diagram editor using the GMF so that I can get to grips with how the XML
Schema maps affects the end diagram editor...
This is the XML Schema I have written, which I thought was correct:
--- START OF SCHEMA ---
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xsd:schema xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
xmlns:wincase="http://www.wincase.dcs.shef.ac.uk/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.wincase.dcs.shef.ac.uk/">
<xsd:complexType name="Wincase">
<xsd:sequence>
<xsd:element maxOccurs="unbounded" name="useCaseDiagram"
type="wincase:UseCaseDiagram"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="UseCaseDiagram">
<xsd:sequence>
<xsd:element maxOccurs="1" name="system" type="wincase:System"/>
<xsd:element maxOccurs="unbounded" name="Actor" type="wincase:Actor"/>
<xsd:element maxOccurs="unbounded" name="association"
type="wincase:Association"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="System">
<xsd:sequence>
<xsd:element name="title" type="xsd:string"/>
<xsd:element maxOccurs="unbounded" minOccurs="1" name="usecase"
type="wincase:Usecase"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Actor">
<xsd:sequence>
<xsd:element name="name" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Usecase">
<xsd:sequence>
<xsd:element name="name" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Association">
<xsd:sequence>
<xsd:element name="Source" type="wincase:Actor"/>
<xsd:element name="Target" type="wincase:Usecase"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
...but i'm experiencing some issues which I hoped somebody may be able to
advise me on :)
1) When I create the Graphical Definition the wizard (making
UseCaseDiagram) the diagram element) it correctly identifies the Actor,
System and Usecase elements as nodes, but it also identifies the
Association element as a node which should be a connector (so I have to
make it one manually). It does correctly identifies their subsequent
labels.
2) It does the same when you create the Tooling definition, again having
to select it manually.
3) Lots more tweaking needed when you create the Mapping definition and it
always gets the System and Actor Diagram Nodes mixed up.
I then generate the generator model and run it as a plug-in and it half
works - lets you create Actors and Systems, Usecases can't be made for
some reason and no chance to try Association without it.
Anyway if anyone could share any light on it i'd really appreciate it, i'm
probably missing something obvious.
Cheers in advance :D
