[Quickfixj-users] Question about "NoHops" at messageHeader

[<cai...@ho...>]

Hi,All
 
Recently, I find that, in QFJ_1.2.1, I can't use the repeating group "NoHops"and the fiels 628,629,630. I only can use field 627.
 
Because repeating group "NoHops" is the only group at messageHeader, so in many places, we may ignore it! For example, at DataDictionary.java,
 
    private void load(InputStream inputStream) throws ConfigError {           
    
     ……
 
     // HEADER        NodeList headerNode = documentElement.getElementsByTagName("header");        if (headerNode.getLength() == 0) {            throw new ConfigError("<header> section not found in data dictionary");        }
        NodeList headerFieldNodes = headerNode.item(0).getChildNodes();        if (headerFieldNodes.getLength() == 0) {            throw new ConfigError("No header fields defined");        }
        for (int i = 0; i < headerFieldNodes.getLength(); i++) {            Node headerFieldNode = headerFieldNodes.item(i);
            String nodeName = headerFieldNode.getNodeName();            if (nodeName.equals("field") || nodeName.equals("group")) {                String name = getAttribute(headerFieldNode, "name");                if (name == null) {                    throw new ConfigError("<" + nodeName + "> does not have a name attribute");                }                String required = getAttribute(headerFieldNode, "required", NO);                if (required == null) {                    throw new ConfigError("<" + headerFieldNode.getNodeName()                            + "> does not have a 'required' attribute");                }                addHeaderField(lookupXMLFieldNumber(document, name), required.equalsIgnoreCase("Y"));            } 
    ……
   }
 
It only load  <group name="NoHops" required="N">  from  fix44.xml, but can't load  <field name="HopCompID" required="N"/>、<field name="HopSendingTime" required="N"/>、<field name="HopRefID" required="N"/> which are in the group.
 
So, maybe, we should add: 
         if (nodeName.equals("group")) {             String required = getAttribute(headerFieldNode, "required");             if (required == null) {                 throw new ConfigError("<group> does not have a 'required' attribute");             }             addHeaderXMLGroup(document, headerFieldNode, this, required                     .equalsIgnoreCase("Y"));         }        } 
 
there, I used a new function:addHeaderXMLGroup(),coming from addXMLGroup(). 
 
This question may  relate to addXMLComponentFields()、addXMLGroup()、addGroup()、isGroup()、getGroup()、checkGroupCount()、iterate() at DataDictionary.java; and parseGroup()、parseHeader() at Message.java; where ignore the only group at messageHeader "NoHops". And after messageCodeGenerate, I can't "public static class NoHops extends Group";  
 
How do you think this question? Am I understood?  Any questions please let me know:)  Thank you very much!
