Christoph Tavan commented on THRIFT-1277:
-----------------------------------------

What was wrong with the original patch? As far as I can see all parameters get 
initialized to null or some default value in the constructor. The constructor 
then overwrites these defaults only if 

{code:javascript}
if (args.varname !== undefined) {
}
{code}

Consequently we cannot get properties that will be undefined. So we cannot have 
the case mentioned by Wade. I think we should do strict checking for null.

It would be great if the strict checking patch could be applied again since it 
will not break jslint.

The lack of correct null checking however breaks quite a lot of stuff (like 
THRIFT-1297).

If anyone's worried that a parameter could somehow get set to undefined we 
could still use

{code}
out << indent() << "if (this." << (*f_iter)->get_name() << " !== null && " << 
endl;
out << indent() << indent() << indent() << "this." << (*f_iter)->get_name() << 
" !== undefined) {" << endl;
{code}

but I can't imagine how that could happen.
