This week I was attempting to prototype a workspace in F&O. After walking through the 'Pattern' I applied to the newly created form, I ran my workspace and ran into this error:
It doing some testing I found that once I got to the 'Form Part' of the 'Tab Page' of the pattern, I had to specify a menu item for the form part. This, basically, shows another form inside your workspace form. Once I specified that, it worked great.
