I have this structure:
Note that tabs are created within a4j:repeat and each tab contains a4j:status.
During an ajax update (i.e. the commandButton is pressed), everything works as expected, a4j:status displays the startText, then ends when ajax is compete. However, on the other tabs, the a4j:status startText never goes away.
In other words, a4j:status works correctly only on the currently active (selected) tab. After an ajax operation, all other tabs still show the start text.
