Need different processes for Update and Delete buttons

Question

I'm using a customized version of the Issue Tracker sample application. I've added a table called project_person(project_id,person_id) so that a project can have multiple people assigned to it and so that one person can have multiple projects. I have a form report that lists all of the projects with an edit link which opens one project. On the individual project page, there are page items for each of the columns in the project table and a item for the person assigned to the project--this item is pulled from the separate project_person table. I have two buttons--Delete and Apply Changes. If you click on Apply Changes, the project table should be updated and then the project_person table if the assignment was changed. If you click on Delete, it should delete the project_person record first and then delete the project record. I created a new conditional pl/sql process that updated two tables if 'Apply Changes' button is cliicked. I then created a separate conditional process when the Delete button is clicked. This conditional process checks to see if a record in the project_person table exists, and if so, delete the record. Then delete the project record.
The update process works fine. The delete process reloads the list of projects with a success message at the top without actually doing a delete and I have no idea why. Does anyone have any suggestions?
I am not using the automatic row processing, but should I? Or is it ok to have the two separate conditions for the two different buttons?

Answer 1

Hello again Miah,
Check the "Sequence Number" for your processes. Typically, APEX will increment by 10, each time you create a Page Process as I recall. You can set this to be any number you want; even if you duplicate the sequence number (ie: you can have multiple Sequence 10 processes).
Make sure that your Delete process is firing properly and walk through the logic in the source code to be sure that any "IF" or "WHERE" logic is satisfied. For example:
Begin
  delete from emp_table
    where 1=2;
End;If this was your page process code - you would receive a SUCCESS message because the PL/SQL code executed successfully, even though nothing will be deleted since 1 will NEVER equal 2.
So, check Delete Source carefully.

Good luck,
Don.
