Called DataObject.find on null

3308441Jul 3 2020 — edited Jul 3 2020

I am attempting to create a desktop application using the Java Developer role in Oracle JDeveloper 12c and trying to add a JFrame Form to the Project, but I receive the error "Called DataObject.find on null".

Here are the steps I performed:

==================================================

First I chose File > New > Application.

Under General > Applications I chose Java Desktop Application

I kept all the default options by selecting Finish.

I right clicked the project and selected New > From Gallery.

Under Client Tier > Swing/AWT I chose JFrame Form.

I kept the default name and package by clicking Finish.

==================================================

The error message flashes very quickly then disappears, the New JFrame Form window remains open, and no JFrame is added.

I had to keep hitting the Finish button just to read the error message.

Questions:

1. What is the cause of this problem?

2. How can I submit a ticket or a bug report (and to whom)?

3. Is there a way to view a log or report to analyze what is happening?

4. What is the most common way of creating JFrames with JDeveloper?

Thanks for your help, community.
