Problem with ob start buffer function and wp_editor

Hi,

We are developing a website on WP and I feel stuck with a problem, hope you guys can help me with this.

I´ve got a page with 2 wp_editors. To use the html wp_editor content im using ob_start() to get the content and insert it in a variable, just like this:

ob_start();
wp_editor( $x, $y, $z );
$editor_contents = ob_get_contents();
ob_end_clean();

I use the same code for a second wp_editor.
The problem appears when i save the data… the content of the sectond editor gets save in the first editor field.

I tried to flush the buffer but not result.

Any suggestions?
Thank you all
