Modules display ID validation does not work with Paragraphs anymore

Just looking at this a bit, I don't think isEmpty() was actually validating though. There is a validate() method on the grantparent class of ViewsReferenceItem, so perhaps we should be extending that method.

I think I worded it incorrectly. The isEmpty() method was used to check whether the display_id was empty before the validation took place.
Which class do you mean? I couldn't find a validate() method in the class that ViewsReferenceItem extends.

Thanks for opening MR, is this ready for review?

Yes, ready for review. we can use validateDisplayId method which is present in ViewsReferenceTrait.php.
Please review MR !67.

Thanks for the progress on this! Tested this out, couple issues:

• This only works if the paragraph is the first one
• The validation from setErrorByName doesn't actually set the error to the display id field

@scott_euser, Thanks for review, I have updated MR.
