Connection source and target in XMI file [message #175132]

Hi All,
I generated gmf diagram and XMI file (which is like xml file for diagram)
and are working fine.

when I draw a connection line to connect elements of diagram from source
element to target element, in xmi file it shows element's index number
instead of the name of elemnent. like: (components.0 , components.1 ....)

(conns, hcomponents and components are EReferences with containment true
in model)

<conns source="//@hcomponents.0/@components.1"
target="//@hcomponents.0/@components.0"/>
<conns source="//@hcomponents.0/@components.1"
target="//@hcomponents.0/@components.2"/>

I want to have names of source and target elements in xmi file instead of
their index numbers.

Any hint how can I do it.

Thanks in advance.

Noor,

This is more an EMF question. What you see here are fragment paths that
specify how to get from the root of the resource to the object being
referenced. If you want something that's more symbolic, you'd need to
define IDs or your object (an EAttribute with isID true) or use a
resource implementation that generates associated IDs (overrides
XMIResourceImpl.useUUIDs to return true).

Noor,

Follow this tutorial and be sure to invoke Generate Test Code so you can
look at the generated example.

http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse. emf.doc/tutorials/xlibmod/xlibmod.html

I'm not sure what to point you at in terms of getting GMF to separate
your model from your diagram file...

This document shows the annotations on the Ecore model that correspond
to the information in the XML Schema.
