10.4 Creating Custom Objects in DocApp

We can now create the objects we require in our custom DocApp. Using DAB we can create various types of Documentum objects like lifecycles, workflows, Permission Sets, object types, Methods, Jobs, and many more. We can do either of the following:

  • Choose an existing object from the Docbase and simply include it in the custom DocApp. To do this, choose Insert | Object from Docbase.
  • Create a new object from scratch and include it in the DocApp. To do this, choose menu option Insert.

Tip

If you make some changes to the objects and are not ready to check-in the DocApp into the Docbase, it is good practice to choose File | Save As and save the changes to a file on the local file system. You can later load these saved changes by choosing File | Open.

Once you save the changes (in the form of a *.dpa file), internally Documentum creates a *.ser file along with it.

In order to remove an object from DocApp, a common mistake committed by most developers is to select the object and choose Edit | Delete Object(s) from Docbase. This should not be done since this destroys the object from the Docbase itself. When you need to simply remove an object from your custom DocApp, select the object and press the Delete key.

Documentum application design is not just limited to understanding Application Builder and objects. There is much more to it, and as you progress on your journey in this book, you will discover many other areas where you can put in meticulous thought to implement a content management system tailored to your specific business needs.

In the next chapter, we will design and create object types and attributes for our News article example.
