I would like to know if it is a real bug or intended behaviour:
I'm using ChoiceQuestion with choices of folders, where I can have . and .. among other results, e.g.:
[1] .
[2] app
[3] src
When I type "." I get an error: Value "." is invalid because of regular expression: '/^[a-zA-Z0-9_-]+(?:,[a-zA-Z0-9_-]+)*$/'.
But when I type "1", the value correctly passes validation and ChoiceQuestion returns array(1) { [0] => string(1) "."}.
I think both variant ("." and "1") should be allowed in this case.
If you think this is a bug, what would you like to see as a solution:
- allowing some range of special characters in the regular expression
- allow providing custom regular expression
- something else
(I want to contribute for the first time to Symfony so directions/advices are much appreciated)
Thank you.
