When creating/initializing a tabbar using the html div method a null parent tab is being create around the specified tabs. Does not occur in Firefox or Chrome.
<div id=“mainContent” mode=“top” tabheight=“25” align=“left” offset=“20”
margin="-10" class=“dhtmlxTabBar” imgpath="/og/codebase/imgs/"
style=“margin-top: 9px; padding-left: 40px; height: 800px;” oninit =“tabbarOnLoad()”>
…
…
The tabs are create correctly but they are created inside a parent tab. Can email screen if requested.
a) Are you using latest version of dhtmlxtabbar or some older one ?
b) Is the code in your case exactly the same as in provided snippet? Older version of tabbar can produce such output if there is any html node ( even html comment ) between top level div and first tab div.
I’m using version dhtmlxSuite_2008Rel3_pro_81009.
This is the exact div element.
The issue is not consistent, it happens approximatly 1 out of 10 times the page is loaded/refreshed
<div id=“mainContent” mode=“top” tabheight=“25” align=“left” offset=“20”
margin=“-10” class=“dhtmlxTabBar” imgpath=“/og/codebase/imgs/”
style=“margin-top: 9px; padding-left: 40px; height: 800px;” oninit=“tabbarOnLoad()”>
<div id=“a1” width=“90” name=“Personal”> <%@include
file=“personal.jsp”%> </div>
<div id=“a2” width=“90” name=“Associate”><%@include
file=“associate.jsp”%></div>
<div id=“a3” width=“90” name=“Counters”><%@include
file=“counters.jsp”%></div>
<div id=“a4” width=“90” name=“Licensing”><%@include
file=“license.jsp”%></div>
<div id=“a5” width=“90” name=“Organization”><%@include
file=“organization.jsp”%></div>
<div id=“a6” width=“90” name=“Comments”><%@include
file=“comments.jsp”%></div>
<div id=“a7” width=“90” height=“100%” name=“Reports” ><%@include
file=“reports.jsp”%></div>
</div>

Please try to use attached js file instead of original one - this is fixed version for tabbar-81009
We can’t reconstruct the issue while using your code, not with build 81009, not with latest code.
