Re: Strings with Templates not working?

Hello,

I'm using a template to simulate a LinkedList from Java.It works without
problems, but when I want to use strings in main.cpp instead of char*, I
get the following error message:

$ ./Main
terminate called after throwing an instance of 'std::logic_error'
   what(): basic_string::_S_construct NULL not valid

I tried to import <string> both in main.cpp and listT.h, but the
errormsg was the same.

The classes look like this:

template <class T>
T ListT<T>::get(int i) {
     TKnoten *iterator = new TKnoten();
     T daten = 0;

     iterator = kopf;
     while (iterator->next != 0) {
          if (iterator->index == i) {
             daten = iterator->daten;
          }
          iterator = iterator->next;
     }
     delete iterator;
     return daten;
}

What's wrong with string as type? I'm using Linux with gcc (g++),
