Warning: The exception to the rule of "Always use a top level Data Collection for tree selection" is when your tree starts at a detail group, and the parent group in your application structure does not have a tree layout. In that case, the first tree group should use a child Data Collection of the parent group for tree selection, to prevent that the default row shown does not belong to the selected parent. When you run the application, search for a department that has employees (for example 'Marketing'), and click the Employees subtab. Only then the tree is shown, containing only employees of the selected department, and already a "default" Employee row is selected. As you can see, the "default" employee (that is shown before any tree node was clicked) belongs to the right department. This is because we set the Data Collection of the Employees child group to the child usage of Departments, instead of using EmployeesViewTreeSelect. If you would have used EmployeesViewTreeSelect, you might see employee 'King' by default, which is not an employee of the Marketing department. We are faced with a dilemma when we select a Department like 'Executive'. This department has 'King' as one of its employees, who manages employees that are not in department 'Executive'. When we select Hartstein in the tree, we still see employee 'King' in the Edit page. There is an error message ' JBO-25020: View row of key oracle.jbo.Key[201 ] not found in EmployeesIterator'. Of course, the EmployeesView3 usage now includes only the employees of Human Resources, which does not include Hartstein! 5 - 36 Generating Page Layouts JHeadstart Developer’s Guide
Warning: This issue (selecting a tree node does not work) can only occur when all of the following conditions apply: 1. The tree starts at a child group 2. The tree starts with a recursive (self-referencing) View Object 3. The direct children of the parent might have recursive children that are not a direct child of the parent. Suggestion: You can solve this by changing the Data Collection of the highest tree group. The Data Collection you specify should contain every possible selectable tree node of this View Object, including the drill-down nodes. If you cannot implement this using a child usage of the parent group, then there is a workaround: temporarily change the layout style of the parent group to tree, then pick any Data Collection you want for the child group (for example 'EmployeesViewTreeSelect'), and change back the layout style of the parent. This reintroduces the risk of showing the wrong initial row, however (but that might be preferable over not being able to select some of the tree nodes).
