On Aem instance 6.5.2 we have a multifield issue related to deletion, steps to reproduce the issue:

• Drag a component into parsys which have smart image field (sling:resourceType : cq/gui/components/authoring/dialog/fileupload) into the multifield

• Add atleast two items into multifield

• Now delete the first element
• You will observed that all the data copied from second to first except the smart image (fileupload) data, which is causing two items still present in multifield

Here one more issue I found while testing above scenario: When we switch the multifield  items(dragging second item to first place), all other data changes its position, but image is still not changing its position. This is happening when image field is with any other field. If only smart image field is there in multifield its working fine.

Note:

• Issue is only occurring when we have smart image item (sling:resourceType :  cq/gui/components/authoring/dialog/fileupload) in multi-field.
• Issue is there in AEM 6.5.3 version also.
