Well problem is in JavaScript
What did I do:
1. Download xk class v1rc2.zip put wysiwyg to class
2. Edited news\include\storyform.inc.php
include_once XOOPS_ROOT_PATH."/class/xoopsformloader.php";
include_once XOOPS_ROOT_PATH."/class/wysiwyg/formwysiwygtextarea.php";
$sform = new XoopsThemeForm(_NW_SUBMITNEWS, "storyform", XOOPS_URL.'/modules/'.$xoopsModule->getVar('dirname').'/submit.php');
$sform->setExtra('enctype="multipart/form-data"');
$sform->addElement(new XoopsFormText(_NW_TITLE, 'title', 50, 80, $title), true);
//$sform->addElement(new XoopsFormDhtmlTextArea(_NW_THESCOOP, 'hometext', $hometext, 15, 60, 'hometext_hidden'), true);
$sform->addElement(new XoopsFormWysiwygTextArea( _NW_THESCOOP, 'hometext', $hometext, '100%', '400px',''), true);
//Extra info
//If admin -> if submit privilege
if ($approveprivilege) {
//$sform->addElement(new XoopsFormDhtmlTextArea(_AM_EXTEXT, 'bodytext', $bodytext, 15, 60, 'bodytext_hidden'), false);
$sform->addElement(new XoopsFormWysiwygTextArea( _AM_EXTEXT, 'bodytext', $bodytext, '100%', '400px',''), true);
3. Download koivieditor class v1.0 rc3.zip and overwrite
\class\wysiwyg\include\js files with source files from v1.0 rc3
Now everything works fine :) and I am happy :)
