Creating dynamic EntityObject, ViewObject and wire them to UI components

Question

hi experts,
Good morning to all :)
here i h'd a problem in real time (while on customization).
My problem: goes here
Re-drawing UI
ok.i through this link
http://jobinesh.blogspot.in/2010/06/model-driven-approach-for-building.html
jobinesh project is fine.
but i h'd a doubt in that project(my doubt goes At end of the thread).
Basis on the real time requirement what I did means?.
i added a new field(SNO) in db. in am just a new created field in am(as select statement).
jobinesh codes in am
    private String getQuery(String viewName) {
        String query = "";
        if (DEPT.equals(viewName)) {
            query = "SELECT Departments.DEPARTMENT_ID, \n" +
                    "       Departments.DEPARTMENT_NAME, \n" +
                    "       Departments.MANAGER_ID, \n" +
                    "       Departments.LOCATION_ID\n" +
                    "FROM DEPARTMENTS Departments";
        } else {
            query = "SELECT Employees.EMPLOYEE_ID, \n" +
                    "       Employees.FIRST_NAME, \n" +
                    "       Employees.LAST_NAME, \n" +
                    "       Employees.EMAIL, \n" +
                    "       Employees.PHONE_NUMBER, \n" +
                    "       Employees.HIRE_DATE, \n" +
                    "       Employees.JOB_ID, \n" +
                    "       Employees.SALARY, \n" +
                    "       Employees.COMMISSION_PCT, \n" +
                    "       Employees.MANAGER_ID, \n" +
                    "       Employees.DEPARTMENT_ID\n" +
                    "FROM EMPLOYEES Employees";
        return query;
    }i added new field in db. say SNo
so i modify the code as follows
    private String getQuery(String viewName) {
        String query = "";
        if (DEPT.equals(viewName)) {
            query = "SELECT Departments.DEPARTMENT_ID, \n" +
                    "       Departments.DEPARTMENT_NAME, \n" +
                    "       Departments.MANAGER_ID, \n" +
                    "       Departments.LOCATION_ID\n" +
                    "FROM DEPARTMENTS Departments";
        } else {
            query = "SELECT Employees.EMPLOYEE_ID, \n" +
                    "       Employees.FIRST_NAME, \n" +
                    "       Employees.LAST_NAME, \n" +
                    "       Employees.EMAIL, \n" +
                    "       Employees.PHONE_NUMBER, \n" +
                    "       Employees.HIRE_DATE, \n" +
                    "       Employees.JOB_ID, \n" +
                    "       Employees.SALARY, \n" +
                    "       Employees.COMMISSION_PCT, \n" +
                    "       Employees.MANAGER_ID, \n" +
                    "       Employees.DEPARTMENT_ID,\n" +
                    "       Employees.SNO\n" +
                    "FROM EMPLOYEES Employees";
        return query;
    }that field is rendering in the dynamic ui.
here the doubt is:
1.*how can i added lov for sno*. why am asking means that field is not in vo only in db. just am field add in select statement. if am wrong correct me.
2.Coming Dynamic UI. Jobinesh shows some readonly dynamic af: table. I need some editable i have to perform CRUD operation and transaction is it possible.

Answer 1

ADF7,
this all looks really complicated. Do you really need the ui that dynamic?
If yes, you'll need to pay the price for it. Price for you is that you don't get much help here as nobody has the time to work through all of this (if she/he isn't doing this already).
I try to point out some things without knwoing the detail:
Q1: I don't understand your question. As you added the new attribute to the query it should be part of the resulting VO (that what dynamic VO is about).
Q2: Jobinesh showed the solution in use case 3. It's more work and you might run in trouble on the way (read the comments...), but this look like the way to go.
