RE: [wsrp-interfaces] copyPortlet

Say the portlet (A) in the page designer use case to be cloned/copied has properties and values: x=1 and y=2. The new copy/clone (B) would initially have the same property values for simple non-computed properties, but what about after:

A.x = 3;

B.y = 4;

What is the expected resultant value of A.y? So far, we have made no assumptions here (the write to A.x could also modify A.y if y was computed from x), but I would expect a copy/clone across registrations to help preserve A.y == 2. If we named the operation "copy" then I would be further encouraged to expect no post copy relationship between A and B, even if the two registration handles happen to reference the same registration, and this would, I think, be expected by Rich's use case, but not our necessarily our 1.0 clonePorlet.

Do we agree that there are such use cases where breaking any relationships between a portlet and its copies/clones is a requirement? If so, then a new copyPortlet operation makes sense (rather than overloading clonePortlet). Computed properties can still take on any value they like, but we would be encouraging producer/portlet property relationships to respect registrations.

If I understand correctly, the only difference between clone and copy is the relevance of the registration. Therefore, I would say that this use case is applicable for both clone and copy. The clone() method, I believe, currently supports this use case due to the requirement of copying the current state from the original portlet to the clone being created. Is this not true for copy() as well?

Could be applicable, I agree. In selecting the use case, focused on requiring two registrations and involving an end user.

I wonder if the following is not another use case that the copyPortlet factory proposal is seeking to solve (note that the problem this use case raises is more acute when portlet hierarchies are involved):

A page designer spends a significant amount of time tweaking the customizations of a portlet for a particular set of pages in order to provide maximum benefit to the users of those pages. The page designer is then given a task for another set of pages for which use of that same portlet will only require small changes in the set of customizations used for the first set of pages. Rather than starting again or (potentially) having future changes to the customizations of the first portlet bleed into the pages using it the second time, the page designer would like to produce an independent copy of the customized portlet and use that as the starting point for the work on the new set of pages.
