Thanks Jody,
I try it without the isEmpty() test but i keep the warning. now i try
to use a debugger (the eclipse one). I have never use it before so
this not very helpful for me. I send you the execution stacks. this is
the same code but here the static method retrive is now in the class
DaoParcelle2.
I have found a very strange things. I have exactly the same method for
an other table ( haies_line) and this one doesn't send me this warning.
Maybe this one come from my PosGis dataBase ??
good weekend every-body.
