In tinyMCE editor all tagged text it cuts off

[eluser]mstdmstd[/eluser]
Hi,
in my CI 2.1 project with smarty I use tinyMCE editor

Code:

[removed][removed]
[removed]
  tinyMCE.init({
        mode:"textareas",
        theme: "advanced" /* "simple" */,
        language:"en",
    });
[removed]
...

<textarea id="content" name="content" rows="12" cols="100">{if $Cms_Item neq ""}{$Cms_Item.content}{/if}</textarea >

It works, but it cuts off all tagged text. Can it be fixed?
