    [ https://issues.jboss.org/browse/RF-13278?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12932826#comment-12932826 ] 

Alexey Shakov commented on RF-13278:
------------------------------------

In my use case I have an active tab with a large tree and I need to refresh an inactive tab header on certain operations. Refreshing the tabPanel completely means rerendering of the large tree, placed in active tab. Only the traffic overhead is easily 1000x higher in the case (tree has a very verbose markup)

> I use ajax to update the header label of rich:tab. That is why label is placed in a header-facet. Since RF 4.3.4 this does not work:
