Thank you for the response. You are right – it is not possible to create control fields as a CMDB class attributes and the only way to add such fields is to do it using standard development method. Developer Studio creates fields by sending Remedy API commands to ARS server. The only drawback of using Developer Studio is a need to do the same operation (creation of overlays and adding the same fields) on 70 AST:xxx forms.
On the other hand javadriver program uses the same API so it should be possible to send to ARS server the same API commands as generated by Developer Studio. After creation of a javadriver script for one form you can easily make copies for remaining 69 forms. That way I can customize AST:xxx forms faster in compare to usage of Developer Studio. I’m able to create or modify data fields or table columns but I cannot find any information how to do the same with control fields (buttons, navigation bars, etc.).
