Twig tag cannot get resolved inside nav_widget tag

[kafuton]

Code is as below:

{{ nav_widget({
'options': {
'class': 'navbar-nav navbar-right',
},
'items': [
{ 'label': "Welcome, {{ app.user.identity.username }}", 'items': [ { 'label': 'Logout', 'url': '/site/logout', 'linkOptions': { 'data-method': 'post' } } ] }
]
}) }}

If the logged in username is 'James', but what displayed on web is still {{ app.user.identity.username }}. Thus the twig tag {{ app.user.identity.username }} is not resolved in such case.

Any suggestion?

Use "Welcome, " ~ app.user.identity.username. See doc http://twig.sensiolabs.org/doc/templates.html#other-operators
