[ome-users] NegativeSizeException using getUserDetails

[Bernhard Voigt]

Dear Mario!

I compiled your code and it works fine for me under Beta 3.1.1.

By the way, you need to adapt the check of the returned map, the map will
always have keys that you've originally passed to the query method. It will
have null pointers or objects as values. The objects need to be casted,
before you have access to the methods - this is Ice-specific:

for(im=m.begin(); im != m.end(); ++im) {
      cout << im->first;
      omero::model::ExperimenterIPtr user =
omero::model::ExperimenterIPtr::dynamicCast(im->second);
      if (user) {
    cout << " id: " << user->getId();
      } else {
    cout << " not found";
      }
      cout << endl;
    }

Best wishes! Bernhard
