Hello
I am not sure if this can be usefull, but by calling the 'addRootVariable' on
the navBuilder in the createAccessors() method, the expression works.
{code}
private void createAccessors()
{
createGetRoot();
navBuilder.begin();
String previousReference = "$1";
Class activeType = rootType;
Tree node = tree;
addRootVariable(navBuilder);
{code}
Regards
Christophe.
