Custom multifield validation (Aem 6.2)
Hi,
I'm currently using Aem 6.2. How do I validate a multifield when I use a Javascript file to validate the component as per this article:

As per the article you need to add an "Id" property to your fields if you want to be able to reference them in the backing Javascript file.
Everything works fine as per the article for basic fields, but it seems I can't use that approach to validate a multifield. Am I mistaken? Is there maybe an example using a multifield somewhere I can look at? Are there other ways I can validate a multifield using custom code that is not mentioned in the article? I'm still using Aem 6.2 and the Classic Ui - but please let me know if there are maybe other supported solutions in newer versions of Aem and I can upgrade 
More low-level detail:
<params
jcr:primaryType="cq:Widget"
fieldDescription="Click the '+' to add a new parameters"
fieldLabel="Parameters"
name="./params"
xtype="multifield">
<fieldConfig
jcr:primaryType="cq:Widget"
width="155"
xtype="pathfield"/>
</params>
I added the "Id" field to my "multifield" node - didn't work. I then added the "Id" field to the underlying fieldConfig node - I were able to access the first multifield value in the backing Javascript validation, but the component refused to allow me to edit any multifield values beside the first (Gui broken...) - so I think this validation might not have been written to support multifields?
Any insight appreciated
Thank you
