Hello,
I'm using Eclipse Ganymede (Modeling tools version) and working on a
EMF/GMF project.
I follow the GMF process for code generation :
* .ecore
* .genmodel -> generate model (edit, editor)
* .gmfgraph
* .gmftool
* .gmfmap -> generator model
* .gmfgen -> generate diagram code
##### Exception :
Exception occurred while generating code
Ambiguous definitions
xpt::editor::DocumentProvider::fileEditorInputClassFQName FOR
gmfgen::GenDiagram and
aspects::xpt::editor::DocumentProvider::fileEditorInputClass FQName FOR
gmfgen::GenDiagram for param types []
I didn't understand this exception.
I saw a similar problem on this thread :
news://eclipse.modeling.gmf:80/c6f1ac739ee35b4cf43ba2846fe01 51c$1@www.eclipse.org
but the solution seems to be unappropriate for me, I didn't have the
second problem mentioned by him.
Thanks,
Olivier PATRY

Hi, thanks for answer.
I test the GMF Tutorial, it works (quite) as expected, no error found,
execution ok. (Features seems to not work as expected, maybe a personal
error)
So, the code generation works well on a "from scratch" example.
Notice that my project was created by someone else with an older version
of eclipse(3.3)/emf/gmf(sdk 2.0).
I use the "migrate to GMF 2.1" command on the popup menu on *.gmfgraph
*.gmfmap
I take a look on xpt files but it wasn't clear for me.
Thanks, regards,
Olivier

Did you mean a trace of my xpt file?
Here an excerpt of the DocumentProvider.xpt
«DEFINE throwIncorrectInputException FOR gmfgen::GenDiagram-»
throw new org.eclipse.core.runtime.CoreException(new
org.eclipse.core.runtime.Status(org.eclipse.core.runtime.ISt atus.ERROR,
«editorGen.plugin.getActivatorQualifiedClassName()».ID, 0,
org.eclipse.osgi.util.NLS.bind(
«EXPAND
xpt::Externalizer::accessorCall(i18nKeyForDocumentProviderIn correctInputError())
FOR editorGen»,
new Object[] {element, «IF null == editorGen.application»"«EXPAND
fileEditorInputClassFQName»", «ENDIF»"«EXPAND
uriEditorInputClassFQName»"}), «EXPAND xpt::Common::nonNLS(1)»«IF null
== editorGen.application» «EXPAND xpt::Common::nonNLS(2)»«ENDIF»
null));
«ENDDEFINE»
«DEFINE fileEditorInputClassFQName FOR
gmfgen::GenDiagram»org.eclipse.ui.part.FileEditorInput«END DEFINE»
«DEFINE uriEditorInputClassFQName FOR
gmfgen::GenDiagram»org.eclipse.emf.common.ui.URIEditorInput «ENDDEFINE»
How is this problem related with encoding issue? The ISO-8829-1 encoding
is for the xpt files ?
Thanks again for helping

If I understood you correctly, this template do nothing at all. It juste
copy things ? I'll try to modify things as you said but I didn't know
the xpt usage.
Goodbye,

Hello Olivier,
> Is it a good way to solve this issue?
Well, the "tail" of this template (throwIncorrectInputException, fileEditorInputClassFQName
, uriEditorInputClassFQName) looks not necessary because you are just copying
original template.. Here you can either call original DEFINEs orcreate your
custom one with different parameters... "aspects" folder was designed to
hold "arounds" for the original templates + some custom DEFINEs. If you'd
like to override original DEFINE completely you can put corresponding custom
template in a folder without "aspects" top-level folder...
> What is this code used for?
It is a question to an author of this custom template.. ;-)
