The first revision or revision A should not have a delete button. Every other revision needs to have one, so that's revision B, C, etc. Does anyone have any ideas on how i can do this?
The above part is the footer for the summary revision dialog. It includes the action buttons of save, cancel, and delete. Delete button is the main focus here.
The below part is the JavaScript controller code that tells what the button to do. When the revision is opened it will display the original revisions details along with which revision this is. the close function is simple, just simply closing the dialog without saving the entered and changed information. The save function is also pretty simple, saves the entered data and will show the changes when the save button is clicked on. The Delete function will delete the current revision and move back the the revision before it, so for example, deleting revision C will display revision B. But what I am trying to do is hide the delete button on Revision A(the first revision) so it will not delete the initial revision and keep the delete button display for any other revision.
Thank you developers for your help.
