> I have very simple thrift structure:
> struct FloatProcessValue
> {
>     1: required ID id,
>     2: required Value value
> }
> FloatProcessValue contains only required fileds, so no __isset structure is 
> generated. But when this structure is used in collection with some default 
> values:
> 4: required map<i32, basic_types.FloatProcessValue> mapi32ToFloat = { 
> 1:{'id':0, 'value':0.4}},
> compilation fails because constructor tries to set __isset.value and 
> __isset.id
>      ::simpletest::FloatProcessValue tmp0;
>      ::simpletest::ID tmp1;
>     tmp1 = 0;
>     tmp0.id = tmp1;
>     tmp0.__isset.id = true; // error: ‘class simpletest::FloatProcessValue’ 
> has no member named ‘__isset’
>      ::simpletest::Value tmp2;
>     tmp2 = 0.4;
>     tmp0.value = tmp2;
>     tmp0.__isset.value = true; error: ‘class simpletest::FloatProcessValue’ 
> has no member named ‘__isset’
