Name	Description
Default	XAF uses the conflict resolution strategy from the previous hierarchy level. For example, if you specified the Default value for a class, XAF takes the option value from the Object Space.
None	XAF does not handle conflict resolution automatically. The user can choose the resolution strategy in a dialog window.
Merge	XAF merges changes automatically. If there are conflicts, XAF displays a pop-up window with resolution options.
Ignore	XAF ignores database changes and writes local values to the database.
Reload	XAF ignores local changes and overwrites them with database values.
