constraint for complex and multiple contract

Adding constraint for complex and multiple contract

Hi

Can I add constraint for a variable that it's complex and multiple?

I define family as a complex and multiple contract and adding constraints similar simple contract, but it doesn't work!

It's my code in constraints:

for(row in family){
if(row.A.length() != 10)
return false
}
return true;

If length of A doesn't equal to 10, it shows my error message but after correcting it doesn't work and still show error message!

I'm using Bonita Studio 7.8 community version.
