Hi,
I tried to migrate my plugin(s) from 0.5.2 to 0.6.0 but ran into problems.
I changed the constructor of the Editor class (extending SapphireEditorForXml) from

    public MyEditor(){
        super( MyPlugin.PLUGIN_ID);
        setRootModelElementType( IMy.TYPE );
        setEditorDefinitionPath( MyPlugin.PLUGIN_ID+"/"+resourcePath+"/main.page" );
    }

    public MyEditor(){
        super(IMy.TYPE,
            DefinitionLoader
                .context( MyEditor.class.getClassLoader() )
                .sdef( "a.b.c.MyEditor" )
                .page( "main.page" )
        );
    }

Running this i just get a ClassCastException:

java.lang.ClassCastException: org.eclipse.sapphire.ui.def.internal.SapphireCustomPartDef cannot be cast to org.eclipse.sapphire.ui.def.FormDef
	at org.eclipse.sapphire.ui.FormPart.initChildParts(FormPart.java:121)
	at org.eclipse.sapphire.ui.FormPart.init(FormPart.java:42)
	at org.eclipse.sapphire.ui.SapphirePart.init(SapphirePart.java:179)
	at org.eclipse.sapphire.ui.SapphirePart.create(SapphirePart.java:1206)
	at org.eclipse.sapphire.ui.FormPart.initChildParts(FormPart.java:126)

So it seems I missed something in the migration process. Does anybody have an idea?

BTW, the migration guide says in section 'FormEditorPage' 'context( getClass().getClassLoader() )' to be called in the constructor but there you cannot call getClass() as the object just gets constructed....

Best regards

Nothing obvious jumps out at me just by looking at the top of the stack trace. This will need a deeper investigation. Could you post the full stack trace and a snippet of your sdef around the custom part. I need to see what the custom part is contained by.

The migration for FormEditorPage is correct. Perhaps you meant to reference migration for SapphireEditorForXml instead, which is indeed incorrect as you've described. I have opened a bug and updated the documentation.

Hi Konstantin,
you are right, I meant the SapphireEditorForXml.
I will post the stuff later as I currently switched back to 0.5.3 and need to finish a few things first.
Cheers
