Oracle developer 6i throws this error when you try to open a form module which references objects from a parent form. The easiest workaround is to let form builder start from the same folder where the parent and child form modules are residing. This post doesn’t have anything to do with the main object of the blog page. However, we decided to add this topic over here as we feel we are visited by many oracle developers.
If you still don’t know how to change the properties for form builder to start from a particular folder, please check the image below.
We really hope this information is useful for budding Oracle developers!
