Inputfield editing - frontend

[RuiVP]

I use frontend editor in some of my textarea fields. I do it for a long time, without problems.

Now, after rebuilding one of my sites, frontend editor works on some pages; on other pages the field I'm trying to edit disappears (not for good, only when I'm trying to edit). 
On the back office editor, no problem.

Did it happened to anyone else? Do you have a clue about possible causes?

Edit: On a better thought, I begin to suspect that the pages where front-edit doesn't work are those where the textarea field starts with a hannacode (marked with [[...]] ). I use it some times to embed jumplinks.

Edit2: I'm using TinyMCE .

Edit3: Nop. I tried to render the page without jumplinks, but the problem remains.
