[Quickfix-developers] DataDictionary::isFieldValue doesn't cope with MultipleValueStrin g

[Chris P. <Chr...@BT...>]

Field ExecInst can contain a space separated list of execution instructions.
In quickfix it is defined

    <field number="18" name="ExecInst" type="MULTIPLEVALUESTRING">

When an incoming message contains multiple values, e.g. "G Q" the method 

	  bool isFieldValue( int field, const std::string& value ) const
	  {
	    FieldToValue::const_iterator i = m_fieldValues.find( field );
	    if ( i == m_fieldValues.end() )
	      return false;
	    return i->second.find( value ) != i->second.end();
	  }

will return false and the message will be rejected.  This method does not
take into account the fact that this field type can contain multiple
entries, each of which needs to be checked individually against the
enumerated values.
