How to set an attribute value to the value of another attribute in the EMF editor? [message #417040]

Hello,

if I set the value of the name attribute of an EEnumLiteral in the
Sample Ecore Model Editor the value of the literal attribute is
automatically set accordingly.

How is this done? Can this behavior be set somewhere in the
Gen Model or is it done by extending the editor code?

Thanks,

Reinhold

Reinhold,

That happens because getLiteral is hand implemented as follows such that
if there is no explicitly set literal, the name is used as the literal.

| /**
* 
* 
* @generated
*/
*public *String getLiteralGen()
{
*return *literal;
}

*public *String getLiteral()
{
String result = getLiteralGen();
*return *result == *null *? getName() : result;
}|
