I am working with the operation in Process LC workbench. I pick the Repository -1.0 activity it shows only Read Resource Content operation. The Repository service has many other operations like readResource, updateResource etc.. How I define a new operation from the Repository service in order it shows up in the Define Activity popup screen. Thank you for your help
PS: I am using LC Workbench ES 2.5
All the services are not exposed via Worbench activities.
If you need to use other APIs of Repository service, you might have to write a script and exceute it in 'executeScript' activity.
For reference, you can find some quick starts for repository services here (http://help.adobe.com/en_US/livecycle/9.0/programLC/help/index.html)
Also, if you want these services to show up in the Define Activity popup screen, then you can create your custom component and deploy it.
Steps to create the component are mentioned here (http://help.adobe.com/en_US/livecycle/9.0/programLC/help/index.htm?content=001379.html).
Hope this helps.
