How to Create a ADF Form same like in Oracle Forms

Question

Hi,
I need to create a Form in ADF where in on the top I have two text fields with LOV and one Text with out LOV and a button. Selecting values from the first two should populate the value of thid text
and pressing the button should actually populate the fields below.
Below I have several other fileds of which few are queried from the database and other are calculated fields (aka like control fields in Oracle Forms).
Now I am a Forms Developer and know quite a few things in ADF as well, like creating Master Details Forms and some of the work flows. Some basic functionaliy.
I want to make an attempt to create something like this which is created in Oracle Forms.
What I have tried as of now is create a query and added LOV to first Text. Displayed all the fields as ADF form and on top I have put a ADF Query panel , using this I am able to populate few of the columns.
Can someone tell me what is the best way to do the things which I have mentioned.
TIA

Hi,
If your need is to auto populate other employee fields of the page based on previous 2/3 fields like deptno, empno, loc, then you can achieve this with button action listener. You can add runtime bind variables to your view object and set them with user input values and execute query.
for e.g, you can add below code in your AMImpl class and expose it to UI and invoke it from UI (from page, create a managed bean and call AM method)
/***** Sample code only*****/
public void refreshVO(Integer EmployeeNo, Integer DeptNo, Integer locNo)
ViewObject vo = this.getEmployeeVO();
vo.setWhereClause(null);
vo.setWhereClauseParams(null);
//Adding empNO where clause
vo.setWhereClause("employeeno = :empNum);
vo.defineNamedWhereClauseParam("empNum", null, null);
vo.setNamedWhereClauseParam("empNum", EmployeeNo);
// similarly add logic for DeptNo, LocNo and you can additional check if they are null or not null
vo.executeQuery();
