Did you experience an issue with the existing config? A colon in an unquoted mapping should only be an issue if it is followed by a space.

@kasparsklavins I think that using colons inside an unquoted mapping value is still valid. I can't find any reference to this deprecation. Do you have some link with more information? Thanks!

@javiereguiluz see symfony/symfony#16433

Didnt have problems with it, IDE didnt like it. It's a bug in https://github.com/Haehnchen/idea-php-symfony2-plugin then.

@xabbuh thanks for the link and sorry about the confusion. @kasparsklavins you are right about this deprecation ... but it doesn't affect you in this case:

defaults:
    # deprecated
    _controller: FrameworkBundle: Redirect:urlRedirect

    # not deprecated
    _controller: FrameworkBundle:Redirect:urlRedirect

    # quotes solve all problems
    _controller: 'FrameworkBundle:Redirect:urlRedirect'
    _controller: 'FrameworkBundle: Redirect:urlRedirect'

I'm glad this was just an issue with the Symfony plugin then :)

@kasparsklavins You are right. I checked the plugin's intentions and proposed a fix for this (see Haehnchen/idea-php-symfony2-plugin#733).

@xabbuh thx nice try, but lexer provides different result then, fixed :)

@Haehnchen Thanks for doing it the right way. :)
