Hello,

when trying to use cxbindings, for the xsd file (generated with dtd2xsd.pl from w3c based on the FWorkflow.dtd provided with the DIET distribution) FWorkflow.dtd, and the following command line from the binary directory containing cxb :

./cxb -f /tmp/FWorkflow.xsd -g CPPObjects -i ../../share/XSDGrammar.xml -n sysfera -t ../../share/CppObjectsStd.templates.xml -o /tmp/cxbwf

I got the following error :

The application encountered an error at /Users/dloureiro/devel/cxbindings/cxbindings/libcxbindings/src/CXBindingsInterpreter.cpp, on line 270. The error message is:

CXBindings Version revision 1123build: gcc 421 Aug 6 2012 18:40:33

Do you know where the problem could be located?

this bug is related to references(i.e "ref" attributes) which are not managed now. Planing to add this feature quickly.
