You Cannot Add More Content to a Composed Application Framework Layout

The maximum content for Composed Application Framework on the EnterpriseOne HTML Server has a default value of 4, in order to prevent a layout with too many satellite forms and the user running out of allowed application instances, which is 10 by default. However, you can change this value.

Go to Server Manager for the EnterpriseOne HTML Server, and select "Advanced" under Configuration >Web Runtime. Under the Web Objects Settings section, increase the value of the CafeOne: Maximum contents per layout property and bounce the server.
