Exception thrown when title_format uses multiple select field

[trigau]

Well, actually I don't know what would be the normal behaviour, but sure I didn't expect it to be an error.

To sum up : thanks to recent improvements, I was able to use a select field in title_format... until I change "multiple" attribute of my select field.

Suggestion : instead of throwing an error, perhaps just don't use select field in title if ther is more thant one item selected.

Details

• Relevant Bolt Version: 3.3

Reproduction

1. Bug summary:
   • title_format can use select field type
   • but if multiple attribute of this field type is set to true, an error is thrown in backend listing
2. Specifics:
   • Here is the error message :
     Twig_Error_Runtime in Template.php line 447: An exception has been thrown during the rendering of a template ("Warning: strip_tags() expects parameter 1 to be string, array given") in "@bolt/_nav/_secondary-content.twig" at line 28.
3. Steps to reproduce:
   • Create a new Contenttype
   • Add a field with type "select"
   • Add attribute "multiple: true" to this field
   • Add attribute "title_format: [selectfieldname] to contenttype
   • Update database ad go to backend listing of your new contenttype
4. Expected result:
   • If multiple is not set to true, listing throws no error and title format uses select field normally
5. Actual result:
   • When multiple is set to true, an error is thrown

Wouldn't that just be even weirder? As in you configure something and bolt would just ignore it?

IMO this isn't a bug, it's just what happens when you try to print an array as a string.

Well it could sound weird. The other option is to display all the values stored in the select field.

I think it could be viewed as a bug, because this is allowed and doesn't work. So either it shouldn't be allowed, or it should work, isn't it ?
