I think it's a mistake of expression. But i can't the solution.

tuple OBJ_RST
{

string obj_id;
float val;
string start;
string end;
}

{OBJ_RST} obj_rst=
{<obj_str,obj,time_id,time_id>};

when using obj_rst, either inserting it into the database or writing to the console. it doesn't work,
with error invalid initial expression obj_rst.

here, obj is the dexpre.

if I use {OBJ_RST} obj_rst=
{<",obj,"b","c">}; instead. it doesn't work either.

because obj is the decision expression. How can I solve it?
