Tabbar attachForm - Error: is not a function

Hi, I’m using dhtmlxSuite_v26_pro_101011 in evaluation licence (eval94228038 as reference number) for develop and testing a simple application.
I’ve linked the comprehensive package dhtmlx.js and all was ok.
Developing I’ve found a simply bug in a dhtmlxform.js but is corrected and patched with the script that customer help (Alexandra) sent me (see my Topic “Combo and connectors”).
So, for use the corrected version of dhtmlxform, I must link every script and not use the global dhtmlx.js

    <script src="codebase/dhtmlxcommon.js" type="text/javascript"></script>
    <script src="codebase/dhtmlxwindows.js" type="text/javascript"></script>
    <script src="codebase/dhtmlxcontainer.js" type="text/javascript"></script>
    <script src="codebase/dhtmlxdataview.js" type="text/javascript"></script>
    <script src="codebase/dhtmlxlayout.js" type="text/javascript"></script>
    <script src="codebase/dhtmlxtabbar.js" type="text/javascript"></script>
    <script src="codebase/dhtmlxtabbar_start.js" type="text/javascript"></script>
    <script src="codebase/dhtmlxform.js" type="text/javascript"></script>
    <script src="codebase/dhtmlxgrid.js" type="text/javascript"></script>
    <script src="codebase/dhtmlxgridcell.js" type="text/javascript"></script>
    <script src="codebase/dhtmlxmenu.js" type="text/javascript"></script>
    <script src="codebase/dhtmlxtoolbar.js" type="text/javascript"></script>
    <script src="codebase/connector/dhtmlxdataprocessor.js"></script>
    <script src="codebase/connector/connector.js"></script>

But at line:


I receive an error:

What I’ve forget?
What’s the matter whit my code?


I seems that all necessary js files are included. And dhtmlxform.js is included after dhtmlxcontainer.js. Is the files order the same as on your page ?

Here is the working demo:
