Post Ordering Issue

I have a previous post about the post ordering constraints error. The situation in that post might be somewhat special: the association between two entity objects (master and detail) is a DBSequence in the master table.

Here is a working solution to the generic post ordering issue.

Steve Muench has an article "Forcing a New Dept to Post Before a New Emp Without Composition", which presented two ways to solve the post ordering contraints:

1. Override postChanges() method in the detail/child entity object Implementation java file. For example, if Dept and Emp table, then write below codes in EmpImpl.java file:



2. An even simpler way:


Steve also has a very good article on "Most Commonly Used Methods in ADF Business Components" which lists all common used methods in EO, VO, AM, etc.
