In my component I have a table called Jobs

This table has four different grid layouts (entry points) depending on the role of the current user (differing amounts of information)

However only ONE of these layouts is appearing in the menu options. I suppose I could use one very complex single view, but for speed, v1 of the component has four.

Is this by design or an error. The one table that DOES show in the menu has nothing that distinguishes it from the others

I added a new grid view and that one did not appear as a menu option either, though it does have its own icon on the control panel view

This is because you have underscores in the layout alias.

It is strange I need to fix that in the builder and in the generator.
Underscores are not allowed in the layout alias. This is a Joomla rule.
But if you have this error it is my fault.

I a gonna fix that soon, in the meantime you can remove manualy the underscores in your layout aliases.

Easy to fix.. I should have known better as I think this has occurred in the past.. oh that was me posting on the clients account!

Fixed.
