managed bean Hashmap called createModes, with the name of the Create action
binding as the key, and Boolean.TRUE as the value. As a result of this, the following
expression can be used to check whether the Departments group is in create mode:
#{createModes.CreateDepartments}
Note that JHeadstart always suffixes the name of the Create binding with the group
name, to prevent duplicate binding names when multiple groups are displayed on the
same page.
With this knowledge you will understand the expression that is used to display the
correct page title:
And the rendered property of the New and Delete buttons looks simply like this:
rendered="#{!createModes.CreateDepartment}"
When you press Save in the form page, the onCommit() in JhsPageLifecycle is called,
and this method will remove all entries from the createModes managed bean Hashmap
when commit is successful.
