TinyMCE not working inside tabs

[pjuhen]

Hi,

Maybe this question question has already been answered.

I have a site where I have 4 instances of tinyMCE.

3 on pages without tabs are OK.

The fourth one doesn't work.

The {{ form.media }} is not expanded as it should be in the page source code, and I have a simple textarea.

When I put manually <textarea class="tinymce" cols="40" data-mce-conf="..." " id="id_historique" name="historique" rows="10">

It does work, but if not {{ form.media }} is expanded as nothing.

Thanks,

Regards
