Ribbon Workbench : "1:Attribute - datafieldname of ControlStep cannot be null or empty"

Question

I tried using RibbonWorkbench for CRM 2013 in order to create a button to convert one of my entity into another (pretty much like the qualify lead button does to build an opportunity).

I created a split button, that divides itself into two sections : evolution and incident. I then created the commands behind the two sections and associated two web ressources (JScript) that i before created using the main CRM interface.

And... Well that's pretty much the only things I've did using RibbonWorkbench. But when trying to publish the solution, I'm having an error :

Your solution could not be implemented
Reasons :
1:Attribute - datafieldname of ControlStep cannot be null or empty.

I've search and can't find what the system calls Attribute nor ControlStep. I might have search wrong, but i can't seem to find any clue while searching in the Microsoft Dynamics Community or simply internet.

Can anybody guide me to understand this error ?

Edit : As asked here is the UML Code that has been directly generated by RibbonWorkbench.

Answer 1

This isn't a message that is to do with the Ribbon Xml - it is coming from a Process I think - try creating a solution that only contains the entity that you are trying to edit and then load that into the RibbonWorkbench.

The Ribbon Workbench will export the solution you load then re-import it, so a import fails due to an error with any component then the publish will fail.
