I am trying to use ajax for populating some data to a drop-down based on contents of another dropdown. I have built one version, which works fine, but is against the SW integrity - and that is what I wish to fix.
Now this works just fine. When I change something in my form, my setDepartmentGroup gets called, the Listener gets a call, and my "department" -component is re-rendered with new values as per the call to "SelectItemUtil.departmentListByGroupCode".
However I have in my bean a reference to entity bean:
/The Decision -object has property "DepartmentGroup", where the data should go and stay. Now however, if I write my jsf:
The fact that your property is in some other bean makes no difference. However, there is a validator restriction that says that if that bean's property is not in the selectItem list, you'll get a validation error and backing bean action methods (including AJAX ones) won't fire. You're even more likely to see that situation if the value expression for the listbox references a bean not yet assigned (that is, departmentGroup cannot be resolved because "department" is null).
Add an h:messages tag to the page with global message display enabled and you should see the error.
