[Typo3-dev] problem with Content Record form disappearing

[stefano cecere]

i've finished to develop the alpha state of a new extension (starting 
by 3.7.0 kickstarter)

at first it seemed to werk well.. then i got to this strange behaviour:
editing one of my record (let's call it "job"), the first fields are:
_invisible
_ fe_group
_ author
_ title..

when i write something into "title", and click somewhere outside it, a 
popup window always says :
"This change will affect which field are available in the form.
Would you like to save now in order to refresh the display?"

if i say yes, the form "collapse", and i can't edit anything anymore.
if i say no, i can go on editing the whole record, but once saved, if i 
open it again, everything is disappeared.

the only way i have to edit again some data, is by the list view, 
editing all together the "xx" fields of all records..

it's a strange behaviours, isn't it? also because i don't have any 
strange TCA configuration.. well, no configuration at all, plain TCA as 
it comes out from the kickstarter.


i did read someone having a similar problem, but it seemed to be 
something related to the fe_users field set to varchar instead of 
int(11).

has anybody any idea? is it a bug of 3.7?

i hope to get a tip soon, cause i'd like to release this nice extension 
(a tasks/jobs management for small teams)
