XPages Extension Library
Which feature do I need of the latest Ext Lib release to get access to the customRestService?
But it comes automatically when you install the library, with no other steps to do.
Is it possible to install the extlib.core in combination with the Upgrade Pack 1.
You can either use UP1 or openNTF, but not a combination of both. This custom rest service is in extlib, which means that it should be in the next UgradePack. In the mean time, you should use the openNTF version if you want to take advantage of it.
