[jbosstools-issues] [JBoss JIRA] (JBIDE-13056) NPE when invoking Mapping diagram when model doesn't correspond with DB

[Jiri Peterka (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-13056?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12736627#comment-12736627 ] 

Jiri Peterka commented on JBIDE-13056:
--------------------------------------

Thing is that when Entities doesn't correspond with loaded DB model there should be some "nicer" Error given, not just raw NPE. You can reproduce it simply, just generate entities, add hbm.xml into hibernate console, than change hibernate console configuration to another database with another tables, rebuild hibernate console, expand and try to show mapping diagram. I agree it's not a critical issue.
