Problems with arcpy findAndReplaceWorkspacePath?

Hello,

I can't find and replace a workspace path with the following script:

# -*- coding: cp1252 -*- import arcpy, os arcpy.env.overwriteOutput = True mxd=arcpy.mapping.MapDocument(r"C:\temp_replaceDatasource\Detail.mxd") class ReplaceDataSource(object): def __init__(self): self.mxd = mxd def DataSourcesReplace(self): for lyr in arcpy.mapping.ListLayers(self.mxd, ""): if lyr.isServiceLayer == 1: print lyr.name + " is a WMS Layer" else: print lyr.name + " X " + lyr.dataSource newDataSource = lyr.dataSource.replace("R:\\", "\\\\{}\\{}\\".format("Client", "R$")) print newDataSource lyr.findAndReplaceWorkspacePath(lyr.dataSource, newDataSource) print lyr.dataSource mxd.saveACopy(r"C:\temp_replaceDatasource\Detail_WIBAS.mxd") if __name__ == '__main__': MyClass = ReplaceDataSource() MyClass.DataSourcesReplace()

The print statement looks ok but the path is not replaced - nothing happens with the path? Any ideas why?

output of the print statement

Maybe lyr.save()

Thank you David,

unfortunately I get an error message if I insert lyr.save() after the findAndReplace ... :

line 35, in DataSourcesReplace
lyr.save()
File "C:\Program Files (x86)\ArcGIS\Desktop10.4\ArcPy\arcpy\utils.py", line 182, in fn_
return fn(*args, **kw)
File "C:\Program Files (x86)\ArcGIS\Desktop10.4\ArcPy\arcpy\arcobjects\mixins.py", line 416, in save
assert hasattr(self, '_lyr'), gp.getIDMessage(89003, "No filename set.")
AssertionError: No filename set.

You are using arcmap 10.4.... there are lots of bugs noted on the tech support site, that you may want to look at for example
