[Minh Hoang TO (JIRA)]

    [ https://jira.jboss.org/browse/GTNPORTAL-1288?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12534344#action_12534344 ] 

Minh Hoang TO commented on GTNPORTAL-1288:
------------------------------------------

 My last comment did not point out the root cause of the problem. First, we need to clearify the cases to reproduce issue

Consider a container A, and another inner container/portlet B. Drag B out of A, then drop it on the top level container UIPage/UIPortal (corresponding to Edit Page/ Edit Layout)

1. If the new position of B is below A, then either there is ClassCastException or B disappears

2. If the new position of B is above A, then everything works well

There must be order-related in recursive method saveChildren from class Mapper
