servicemanager - map a custom enum list to a custom form property in an extended incident class in scsm 2012 R2 -

i'm struggeling understand how map custom enum list custom form property in extended incident class in scsm 2012 r2 using authoring tool.

here's want have happen:

i going publish request offering on smportal allowing users submit basic incidents. want form include "whom problem affect" (answers(this custom enum list): me, multiple users, whole department or whole company), "what problem about", "description" , "attachments".

here's i've done:

in authoring tool created mp custom enum list , put list in it. sealed mp , imported it.

i created unsealed mp called tst.incident.library storing incident library customizations , extended incident class add extension class called classextension_affected scope custom property called affectedscope. trying set datatype of property "list". in "select list" dialog cannot chose sealed mp custom enum list in it. why?

• do need scratch sealed mp , put custom enum list in latter tst.incident.library mp instead?
• if so, can , keep mp unsealed, or error on import saying "unsealed management packs should not contain type definitions"
• should create 1 sealed mp both custom enum list , extension class + custom property?

in authoring tool, load sealed mp created first contains custom enum list second unsealed mp. if not both loaded @ same time authoring tool not know custom list in first mp.
