No cooperation between dictionaries from Cint and Reflex

Hi,

The LHCb software framework uses Reflex dictionaries to provide python bindings for most of its C++ classes. To be able to interact with one of the C++ classes from python, I need to be able to create a std::map<std::string, double>. A dictionary for this type exists, but it does not allow me to do the following:

>>> import ROOT
>>> m = ROOT.std.map('string', 'double')()
>>> p = ROOT.std.pair('string', 'double')('one', 1.)
>>> m.insert(p)

The full error message is included at the bottom. It seems that a dictionary is not being picked up for the return type of the insert method, while I believe I have created it as a Reflex dictionary (log of genreflex is attached).

For a similar type, std::map<unsigned long, bool>, generating appropriate dictionaries for the map, pair<const unsigned long, bool>, iterators and the return type of map.insert allows me to perform the same operation. Since the map<string, double> dictionary seems to be a Cint dictionary, I suspect that cooperation between Cint dictionaries and Reflex dictionaries has a problem here. Perhaps the types are slightly differently defined?

Any ideas on what is going wrong?

Cheers, Roel
