Delete sub mappings on CollectionMapping addition
-------------------------------------------------

                 Key: JBIDE-7574
                 URL: https://jira.jboss.org/browse/JBIDE-7574
             Project: Tools (JBoss Tools)
          Issue Type: Feature Request
          Components: smooks
            Reporter: Tom Fennelly
            Assignee: Tom Fennelly
             Fix For: 3.2.0.Beta2


For sources that don't have a schema (e.g. sample xml source), the editor has to allow the user perform mappings that it can normally block the user from doing in situations where there is a schema (e.g. XSD source) e.g. based on schema rules, it can block mapping to sub elements before a parent collection mapping is made etc.

For these sources that don't have a schema, the user could map into a sub element on the target and then (later), perform a collection based mapping onto one of the parent elements.  This CollectionMapping can invalidate the earlier mappings.  In such cases, the earlier mappings need to be deleted and the user needs to remap.  

We could get "fancy" in future and actually fix the earlier mappings to make them part of the new Collection, but deleting the earlier mappings is easier for now.
