I've checked out a component from ESS package (Travel and Expense Component to be exact), I made some changes and checked it back in. Then I activated the activity and finally released it. My changes were related to removing a couple of fields form the General Data View in the esstratre~sap.com package. However, I still don't see the changes being reflected on our Dev runtime system. Activation Results tab shows that the activity was built properly (there is a check on the component). Am I missing something? I also confirmed that we have our runtime systems setup properly in the Dev Track for NWDI.
ESS is a Web Dynpro application and therefore I am thinking a Portal restart should not be required. A simple deployment to the J2EE should do the trick. Do I need to clean the Portal Cache? Not sure what's going on here...
