An object is said to be 'Pending for Update' or in the list of 'Preview objects' when the object has been modified in the linked1 Knowledge Base as of the state contained in the local2 Knowledge Base.
This state has meaning only when the Knowledge Base is linked to a GeneXus Server.
Note1: The linked Knowledge Base is the one to which the local Knowledge Base (opened with GeneXus) is connected to in the GeneXus Server instance.
Note2: The local Knowledge Base is the one opened with GeneXus.
When an object is Pending for commit it will be displayed in the "Pending Commits" List of the Commit to GXserver dialog. This will allow you to Revert all changes made to it or to actually Commit its changes to the Knowledge Base hosted in the GeneXus Server instance.
