sending tables to a lua function
Author
I'm trying to call a lua function from freebasic, constructing two temporary tables as the arguments. The problem is that the function is only receiving one of the tables. Can anyone help me out?
in this code, "ref" is a reference to the lua table that contains the function, created earlier in the program with the lua_ref statement, the table created from the "inputs" array gets passed just fine, but the table created from the "desiredOutputs" array is ending up as nil on the lua side

I just figured it out with some help from the people in #lua on freenode. Because the function I'm calling is a method, the first table was getting put into the "self" argument, so to fix it I had to push the originating table onto the stack before pushing my argument tables
