Since 4.1.2 I am noticing that if I programatically add a tab to a tabpanel whose tab location property is set to HIDE, then I programatically remove the tab, any subsequent attempt to add another tab results in a blank tabpanel; the tab is never displayed even though the max tab count increments.
which is the js code you are using ?
hmmm… strange we do this almost everyvhere. No problems at all in 4.1.2
