dhtmlXComboFromSelect send incorrect data


I have a dhtmlXComboFromSelect(“category”);

<div style="width: 200px;" class="dhx_combo_box">
   <input autocomplete="off" type"text" class="dhx_combo_onput">
   <input type="hidden" name="Printable[category]" value="">   
   <input type="hidden" name="Printable[category]_new_value" value="false">   

A var_dump on server shows:

array ( 'Printable' => array ( 'name' => '' 'network_file' => '0' 'add_footer' => '0' 'description' => '' 'category' => 'true' 'type' => '' ) )

I expect to see the ‘category’ to whatever I type in. Any idea what’s happening ? I am using v.2.1 build 90226

I got the problem fixed after upgrading to latest version 3.0

So I suspect, it is a bug in v2.1
