Issue with the partialTrigger on ADF Table

Question

Jdeveloper Version 11.1.2.3.0
I have replicated issue with partialTrigger on the table component. Sample application can be downloaded from here . It needs HR schema to run.
In below sample pageFragment, I can try refreshing adf table in two ways
1. Set addEmployee button's id in partialTrigger of ADFTable component.
2. Set addEmployee button's id in partialTrigger of PanelBox component.
Note the difference - 1st one doesn't work where as 2nd works fine. Do we have any additional constraints when refreshing ADF table using
partialTrigger ?
I replicated the usecase in below example :
PageFragment Structure -
PanelBox                         
|                              
|__ ADF Table                         
|                              
|__toolbar facet                    
|                              
|__ addEmployee button

Answer 1

Hi Frank,
Indeed it worked. But I have two queries now :
1. We are adding employee record using a method called through method action Binding. So shouldn't the bindings be aware of the same .. i mean sychonization of binding layer should happen when method action binding is used ?
2. Why it works when i apply partialTrigger on panelBox ? Why "employeesViewImpl" code is not required when I apply partialTrigger on panelBox ? Is it a concept that iterator is reexecuted when you refresh parent component ?
Thanks,
Rajdeep
