How to get/publish the items removed from the multilist field

Question

Recently i was trying to get the items which are removed from the multilist field , suppose i have a multilist field and i added 3 items from left side to right side and saved and published those items with the related items checked . with the related items checked i was able to publish that 3 items which are selected in the multilist field also , but when i remove 1 item from the multilist field , then when i publish it with related items checked , only 2 items will be published which are selected in thet multilist , so in my case i need to publish that 3rd item also ( which is removed from th3 multilist ) , because there is a computed field created on that 3rd item and that field will only get reflected when the item is published . The computed field is having bool values true/false for the item selected in multilist/not selected in multilist. So how can i also publish that item which is removed from the field.?

Answer 1

When you don't select [don't move to right side] an item in multilist field then that won't be published even if you check "Publish related items".

Because publish related items basically runs <getItemReferences>. One of the pipeline inside that AddItemLinkReferences will look for the linked items in the published item. It won't find the multilist item if it is not selected / in right side.

Alternate options are you can add a pipeline in <getItemReferences>, where you can get all the items in a multilist whether they selected or not. [but may impact performance] Or you can write your own custom publish processor which does what you required.

But note, all the above mentioned options may impact performance slightly.
