[richfaces-issues] [JBoss JIRA] (RF-11054) Dynamically created tabs within tabPanel causes NPE in getActiveItem()

[Jean ANDRE (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/RF-11054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12641539#comment-12641539 ] 

Jean ANDRE commented on RF-11054:
---------------------------------

Moreover, even if you set the tab by program on action or action listener, during the rendering but after the deletion in your model, we still get the NPE on getActiveItem. Then setting the activeItem does not work in such case.

FacesContext facesContext = FacesContext.getCurrentInstance();
UIComponent desktopTab = facesContext.getViewRoot().findComponent("tabbedForm:desktopTabPanel");
((UITabPanel)desktopTab).setActiveItem("tab-search");

I've also tried to bind the tabPanel with a backing bean, it's  seem that the F5 key show a memory corruption because the tabPanel does not appears except its content !!!

> When set switchType on TabPanel to "server" (notice that with "client" everything works correctly, with "ajax" tab switch not work as well as with "null"), all dynamically created tabs causes NPE on tab switch.
