Hi, I am new at EMF, but have successfully created a model and am
currently reading data from it.
I am trying to use the ecore namespace as default when generation a
model from a schema. Heres the story.
During reading I found that the xsd :
<xs:element name="resulttype">
<xs:complexType mixed="true" />
</xs:element>
Does not allow me to access CDATA like banana
<resulttype>banana</resulttype>
in the generated code.
Adding the ecore namespace to the schema node
and putting mixed in this namespace fixed the problem
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore">
......
<xs:element name="resulttype">
<xs:complexType ecore:mixed="true" />
</xs:element>
now the generated code has the method getMixed() on which I can use the
getValue(0) to get CDATA contents, which is fine.
Back to the question : can I get the emf codegenerator to generate
getMixed as default or define the ecore namespace to be used as default
Regards, Jesper

Jesper,
This was fixed by https://bugs.eclipse.org/bugs/show_bug.cgi?id=86118.
