Order of Attrributes in Entity

I am exporting a non persistent entity to excel using java. I am getting the rows for each record as follows: for (IMendixObject obj : exportList){ int j = 0; Map<String,? extends IMendixObjectMember> mxObj = obj.getMembers(this.context); for (Map.Entry<String,? extends IMendixObjectMember> mxObjEntry : mxObj.entrySet()){ IMendixObjectMember mxObjMember = (IMendixObjectMember) mxObjEntry.getValue(); IExcelColumn col = excelGrid.getColumn(j); IExcelCell cell = col.getCell(i); if (mxObjMember.getValue(context) != null){ cell.setContent(mxObjMember.getValue(context).toString()); } else{ cell.setContent(""); } if (!mxObjMember.getName().trim().equalsIgnoreCase("") && mxObjMember.getName() != null){ j++; } } i++; } Is there any way to force the order of the column to be in the same order that they appear in the modeller's entity model or any other order

In general terms, a key set in a Java Map is unordered. You could impose an ordering on a set by copying its contents to a SortedSet such as TreeSet, or in case of a Map use a TreeMap. Pass it a Comparator<imendixobjectmember> in the constructor that compares two members and returns a negative, 0, or positive value accordingly.

Something like this:

Comparator comp = new Comparator<String>() {
    public int compare(String s1, String s2) {
         return s1.compareTo(s2); // lexicographic order

SortedMap<String,? extends IMendixObjectMember> mxObj = new TreeMap<String,? extends  IMendixObjectMember>(comp);
for(String key : mxObj.keySet()) {
     IMendixObjectMember mxObjMember = mxObj.get(key);
    // fill cell contents

I doubt there is a way of reconstructing the order from the entity model.
