Hi Michael,<br /><br />The "Start Advanced Process" link functionality is provided by Adobe and not Alfresco. We also ship complete source code for this. It's available at - <br /><LC ES Install dir>/Adobe/LiveCycle 8.2/LiveCycle_ES_SDK/misc/ContentServices/adobe-contentservices-src.zip<br /><br />Inside the zip, there's ContentServices folder, which contains a ReadMe.txt and ReadMe_Eclipse_Setup.txt - information for the available source code and how to build up an eclipse Java development environment for it. You can modify the code for process-samples component in order to suit your requirements.<br /><br />In order to understand more on how to work with Alfresco features like UI customization, actions, models etc, please refer
http://wiki.alfresco.com<br /><br />What Avinash said applies to "Invoke a LiveCycle Process" option in the "Run action" link in the More actions side bar (present at right in document details view).<br /><br />Thanks,
