[jbosstools-dev] Re: [JBoss JIRA] Created: (JBIDE-2566) Almost any editing of pages.xml throws a lot of NPE.

[Alexey Kazakov]

Hi,
There are two bugs in new pages.xml editor:
https://jira.jboss.org/jira/browse/JBIDE-2566
https://jira.jboss.org/jira/browse/JBIDE-2565
IMO we should fix them for alpha.
So we will need to retag Seam component and maybe common component too.
