[Brian Leathem (JIRA)]

Brian Leathem commented on RF-13687:
------------------------------------

Looking at the generated HTML:

{code}
...
<td id="form:j_idt41:header:inactive" class="rf-tab-hdr rf-tab-hdr-inact rf-tab-hdr-top" style="display: table-cell;">
  <span class="rf-tab-lbl">
    <span id="form:label">5 clicks</span>
  </span>
</td>
<td id="form:j_idt41:header:active" class="rf-tab-hdr rf-tab-hdr-act rf-tab-hdr-top" style="display: none;">
  <span class="rf-tab-lbl">
    <span id="form:label">0 clicks</span>
  </span>
</td>
<td id="form:j_idt41:header:disabled" class="rf-tab-hdr rf-tab-hdr-dis rf-tab-hdr-top" style="display : none">
  <span class="rf-tab-lbl">
    <span id="form:label">0 clicks</span>
  </span>
</td>
...
{code}

One can see that the label attribute is rendered 3 times: once for each of the _active_, _inactive_, and _disabled_ tab headers.  Only one of the rendered DOM nodes is getting updated with the new value.

This is likely due to the repetition of the {{id}} attribute amongst the three rendered DOM nodes.  This is incorrect HTML, and as such the behaviour is unspecified.  Proper resolution of this issue will involve properly dealing with the active/inactive/disabled tab headers and rendering each tab header only a single time.

> If {{TabPanel}} header is updated dynamically with AJAX, then switching among the tabs shows not the updated value of the header, but the initial one. Its updated after refresh of the page.
