Parser for assembly style constant

Hi,

I tried to write a simple parser for a assembly line constant definition

Label: (dc.t | dc.s | dc.w) constantsList

The constant are:
numeric (decimal) constant
ternary constant (es: 0Tconstant or 0TConstant)
balanced ternary constant (es.: 0BTConstant)
character

My parser is:

		constChar = qi::char_('\'') >> *qi::char_("a-zA-Z") >> qi::char_('\'');
		
		constTernary = (qi::char_('0') >> (qi::char_('t') | qi::char_('T')) >> +qi::char_("0-2"));

		constBalancedTernary = (qi::char_('0') 
					>> (qi::char_('b') | qi::char_('B'))
					>> (qi::char_('t') | qi::char_('T')) 
					>> +qi::char_("0-2"));


		constDecimal = +char_("0-9");

		rConstValues = (constDecimal | constChar | constTernary | constBalancedTernary )[phoenix::push_back(phoenix::ref(constValuesList), _1)] % ','; //Constants list



firstStepRules = labelName[phoenix::bind(&asmGrammar::do_varName, this, _1)]
			>> rSpazi1
			>> (qi::as_string[(no_case["dc.t"])] | qi::as_string[(no_case["dc.s"])] | qi::as_string[(no_case["dc.w"])])[phoenix::bind(&asmGrammar::do_varType, this, _1)]
			>> rSpazi1
			>> rConstValues [phoenix::bind(&asmGrammar::do_firstStep, this)];


If I parse this line:

std::string s("label: dc.W 0bt222,123,12,'A',22,0t212");

If I list the constValuesList (vector of string), I obtain only one 0!!

what is wrong?
