Raising Python exception

[Gaetan Corneau]

I think my original message didn't reach the list, so here it is again:

I'm using SWIG to wrap C++ STL vector and I want to be able to write the
following in my Python scripts:

sv = StringVector() # vector<string>
for s in sv: print s

So, I wrote the following in my SWIG interface file:

struct StringVector{
    StringVector();
    %addmethods {
        char* __getitem__(int i) {
            if (i < self->size()) {
                return (char *)((*self)[i].c_str());
            } else {
                PyErr_SetString(PyExc_IndexError, "index out-of-bounds"); 
                return NULL;                
            }
        }
    }    
};

The problem is that no exception is ever raised when sv[i] is out of bounds.
What's missing?

TIA,
