Weird list (mx2004)

Hello guys,

I had a strange list behavior today.
I have a few lists on which I do no setStyle nor theme application. For a while it has been working quite fine, and by that I mean that I saw my lists on the MC.

But like 20 minutes ago, I wasn’t touching any of these lists but all of the sudden, the content of my lists has disapeared. And by “content” I don’t mean “items”, but the whole list EXCEPT a fine 1px solid border - which I never set.

A picture of the bug is located here :

Has this ever happened to you ?

Any help would be appreciated, thanks in advance
