NumberFormatter fails to parse invalid numbers

[aledeg]

I was trying to validate my form entries using the Type validation with integer type and I get the following error:

Uncaught PHP Exception Symfony\Component\Debug\Exception\ContextErrorException: "Warning: NumberFormatter::parse(): Number parsing failed"

This error does not occur all the time, only when the value to format does not start with a number. So 123dd will return an error but dd123 will fail.

For more information, you could have a look on my stackoverflow question

I am using Symfony 2.6.6. I checked the code for the parse method in the 2.7 and 2.8 branches and it appears to be the same as in branch 2.6.

Edit 1:

To answer a deleted comment about my ICU version, here is the output of the command php -ri intl

intl

Internationalization support => enabled
version => 1.1.0
ICU version => 51.2
ICU Data version => 51.2

Directive => Local Value => Master Value
intl.default_locale => en_utf8 => en_utf8
intl.error_level => 2 => 2
intl.use_exceptions => 0 => 0

Edit 2:

Here is the content of my log file:

[dosten]

This works in an older version? Can you paste the complete stack trace?

[aledeg]

I don't know if this works in an older version. But I think it didn't work.
I check the code that fails in older version of the NumberFormatter class (up to 2.3) and the regex matching a number is the same.

[dosten]

I found that the problem is the intl.error_level option. Can you comment the intl.error_level line in your php.ini or set the value to 0?

[aledeg]

If I change the error_level to 0, I don't have errors anymore.

What I don't understand is why there is two level of validation. If I enter text in an integer field, the validation of type is done by the field. But if I chose to use a text field, the validation of type is done with the validator.

[dosten]

The integer type is rendered as a input[type=number], which have a HTML5 validation by default. see http://symfony.com/doc/current/book/forms.html#form-validation for instructions for disable it.

[aledeg]

Thank you. I knew that but I didn't mentioned it since I am not using HTML5.
I build an API which consume JSON or XML data. That's why I don't understand why there is 2 levels of validation.

[dosten]

You're welcome :) If you need help, you can make a question in the mailing list http://symfony.com/mailing_lists. Is this resolved? Can this be closed?

[aledeg]

I will close it but I am still confused.
