Shay Shmeltzer : How To Build a Simple UIX Search Form

Question

Shay, I need your help here. I need to filter MessageChoice entries by doing setWhereClauseParam on the appropriate VO (The one that acts as a source for the LOV mode for MessageChoice). Say, this VO is in the 'root' level of AM_A.
Everything from here (all VOs) are in AM_B.
Say I am on page1.uix which has a readonly table and submit button. Let's say one of the table COLUMNS contains strings that I need to pass to the AM custom method (The one that will set where clause).
So user selects the ROW and clicks submit. Somehow (how exactly?) string gets passed to data action (that I guess uses custom method, like the one in your example in AM_B). The page forwards to ANOTHER page2.uix. This page is input form with one field as MessageChoice. Now this is IMPORTANT. This message choice has a source driven by the VO that I wanted to set WHERE clause.
I have been trying to do this for a week, tried all kinds of stuff but am never getting it to work.
Please help.

Answer 1

ok, a little sample with the HR Schema.
You are going to display the departments in the first screen, select a department and then use the row that you selected to set the where clause for a new view item that is based on EMP.
So create a new view (call it queryEmp) that looks like this:
SELECT Employees.FIRST_NAME,
Employees.EMPLOYEE_ID,
Employees.LAST_NAME,
Employees.DEPARTMENT_ID
FROM EMPLOYEES Employees
WHERE DEPARTMENT_ID=:1
Then add a method to your applciation module as follow:
  public void setMyWhere()
    ViewObject vo = this.findViewObject("queryEmp1");
    ViewObject vo_master = this.findViewObject("DepartmentsView1");
    System.out.println("valus is "+vo_master.getCurrentRow().getAttribute("DepartmentId"));
    vo.setWhereClauseParam(0,vo_master.getCurrentRow().getAttribute("DepartmentId"));
    vo.executeQuery();
  }Then the struts flow is from the first page that just shows the Departments and allows you to choose one (the radio button in the multi-row table does this for you).
Then add a button that sends you to a dataaction. on this dataaction drag and drop the method you have defined (and made it a client method - setMyWhere)
Then this method goes to a second UIX that shows the information from the Empquery view.
Works for me.
