View criteria condition needs to check value in column from another VO

Question

Hi All,
My Jdev version - 11.1.1.6
My use case is as follows-
2 view objects say EmpVO and DeptVO which have view link with deptId as the foreign key attribute. I need to show the distinct list of departments along with a column which contains the employee names separated by comma for the particular department in the corresponding row. Hence, for DeptVO I use the query as follows -
-          SELECT deptId,
-                 deptName,
-                 (SELECT listagg (empName, ',') WITHIN GROUP (ORDER BY empName)
-                            emp_names
-                    FROM EMP_TABLE emp
-                   WHERE emp.deptId = dept.deptId)
-                    emp_names
-            FROM DEPT_TABLE
This gives me the result on screen as follows -
DeptId          DeptName          EmpNames
101               HR                    emp1,emp2
102               Finance             emp3,emp4,emp5
Now, my requirement is that there should be a search on department which should also contain an LOV (with search icon) for the employee names i.e. if user selects emp4 from the LOV, department table should list the record for 102.
For this , I added an LOV on the EmpNames attribute of DeptVO (to map the values from EmpVO) and added a view criteria based on which I added a query panel on screen and the relevant partialTrigger attribute so that the department table should reflect the search results. I tried 2 options in the View Criteria of DeptVO i.e.
1. Added an Item 'EmpNames = '. WIth this, EmpNames attribute appear with Searh icon in the query panel(which is required) but it does not display the right department record bcz it tries to match exactly with values like 'emp3,emp4,emp5'
2. If I add Item 'EmpNames CONTAINS ' , EmpNames search will work from query panel i.e. if I enter the value as emp4, department 102 will be shown in the results table but there is no Search icon on the EmpNames field in query panel. The component actually becomes an inputText.
It would be of great help if you can guide on a better way to achieve this use case. Please let me know if there needs to a change in the approach or if any other details are needed.

Hi Timo,
Thanks for this. I have already implemented this part. Here, in the example there's an LOV on department id and form is on employee entity. However, my use case is a different one. I need to search for department which should contain a search criteria for employee in the form of LOV.
Could you suggest some possible solution?
