Hi
Thanks. I was looking in the FieldMapping help.
My problem is how from my manual changes in FieldMapping Zone, I can keep the changes. i mean, after right clicking on a field, make changes and see that those changes are kept (as what we can do with merge tool)
Here what I did in validation :
def updateParameters(self):
if self.params[1].altered:
self.params[3].value = None
tfms = arcpy.FieldMappings()
tfms.addTable(self.params[1].value)
self.params[3].value = tfms.exportToString()
return
Thanks
