[Xpand] Accessing enum name values [message #1396862]

Hi,

in my ecore model I have classes with attributes that are enums. The
literals are what the user sees and the names are the values I want to
use in my Xpanded output but I cannot figure out how to do this.

I can access the literal value by in my template declaring:

«this.fileParameter.toString()»

but if I try:

«this.fileParameter.getName()»

then I get the following error:

782 ERROR AbstractExpressionsUsingWorkflowComponent - Error in
Component of type org.eclipse.xpand2.Generator:
EvaluationException : Couldn't find operation 'getName()' for
jas::FileParameter.
template::RDFTemplate.xpt[576,28] on line 18
'this.fileParameter.getName()'
template::RDFTemplate.xpt[371,25] on line 10 'EXPAND rule FOREACH
rules'
[23,42] on line 1 'EXPAND template::RDFTemplate::main FOR jas'

Any advice on what I can try so I can access the enums name?

Thanks for any help, Nigel.

Hi,

which metamodel provider do you use? javabeans? emf(registry)?
emf registry has no sophisticated support for the literals afaik.

as a workaraound you may use a java extension
