[gatein-issues] [JBoss JIRA] Commented: (GTNPORTAL-301) ClassCastException when drag & drop dashboard in create/edit page

[Minh Hoang TO (JIRA)]

    [ https://jira.jboss.org/jira/browse/GTNPORTAL-301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12500439#action_12500439 ] 

Minh Hoang TO commented on GTNPORTAL-301:
-----------------------------------------

 The issue was caused by mapping mechanism in MOP. For Dashboard portlet, there was special treatment basing on application state. For instance, to fix the error, we set appropriated application state on Dashboard portlet during drag/drop process.
