Update as a part of Delete action

Question

Hi,
I'm using Jdev11g, ADF BC and ADF faces RC.
I have a table of records in the UI. In the toolbar I have dragged and dropped Delete method as a button.
What I want to implement is when a user selects a row and clicks Delete button, I dont want the real delete to execute but instead I want to update a column( called 'Status' ) of that row to 'DELETED'.
Also, same time the Delete button click should do a commit. Plz assist.
Thanks,
Anu

Hi,
Here is an approach.
Basically you dont want to delete at all.
1) create a method in your Application Module java class e.g. changeStatusOfViewObjectNameHere()
Inside the method, get the ViewObject you want and get the currentRow.
For this current row, change the attribute value you want with the new value you want
e.g: getVO().getCurrentRow().setAttribute("attnameHere",yourValueHere);
2) expose this method in the client interface of your AM.
3) in your jspx pageDef, create a methodAction in your bindings and point to the previously created method in your AM.
4) in your jspx pageDef, add the commit action as well.
5) In the Delete button, remove the ActionListener that is created by default.
6) In the ActionListener of that button, through the wizard, create a new method in your backing bean ( If the backing bean does not exist, create one).
7) In your backing bean, do the following:
First you need to change the status value of the current row. So, you need to call the AM method already exposed in the bindings:
OperationBinding oper = ADFUtils.getDCBindingContainer().getOperationBinding("*changeStatusOfViewObjectNameHere*");
you can find the ADFUtils in the sample applications in the JDev I think. Or search the Web.
After this call, you have to commit the changes:
So, another OperationBinding should be called:
OperationBinding oper = ADFUtils.getDCBindingContainer().getOperationBinding("*commit*");
make the Delete button to be partialSubmit=false, in order to refresh the whole page.
Hope this will help you.
