You can try something like within your for loop lyr.findAndReplaceWorkspacePath(find_workspace_path=lyr.dataSource, replace_workspace_path=r"C:\Newpath\To\SDE_ConnectionFile.sde") Lots of examples here: Desktop Help 10.0 - Updating and fixing data sources with arcpy.mapping (arcgis.com) ...

I'm hitting the same wall with a very similar issue. Unfortuatenly I think validation code from a working Python toolbox does not carry over to the GP Widget in WAB. This guy had this same problem and 2016 and suggests building the functionality in JS rather than python.

Unfortunately, I can confirm that validation code does not carry over from a Python Toolbox to GP Server. I have a Python Toolbox (not a Script Tool) published as a GP Service to ArcGIS Enterprise 1081. The toolbox has validation code to update a parameter's drop down lists based on the user updating another parameter. This functionality does not carry over to the GP Widget in Web AppBuilder after publishing as a GP Service.  ... View more

I need the the index of the GIS Server the user selects as a variable to use later on in my execute. Using parameters[3].valueAsText  does not provide this.  I did figure this out though, so thank you for you help! def execute(self, parameters, messages): """The source code of the tool.""" # Input Parameters startTime = time.time() portal = parameters[0].valueAsText user = parameters[1].valueAsText password = parameters[2].valueAsText # Based on which server the user selects for the GIS Server drop down, get the Index Number for that to pass into the rest of the script if parameters[2].value: # If the password field is filled in gis = GIS(portal, user, password, verify_cert=False) # Connect to the GIS Portal serverList = gis.admin.servers.list() # Build a list of GIS Servers # Convert each item in the serverList to a string and add it to a new list newList = [] for item in serverList: myString = str(item) newList.append(myString) x = newList.index(parameters[3].valueAsText) # Get index value from the server list based on which server the user selects ...   ...

This is what I've tried so far, but I need to be able to use the variable 'b' in my execute function. Any ideas? def updateParameters(self, parameters): """Modify the values and properties of parameters before internal validation is performed. This method is called whenever a parameter has been changed.""" # Create a dropdown list for the GIS Server Parameter of all federated GIS Servers portal = parameters[0].valueAsText user = parameters[1].valueAsText password = parameters[2].valueAsText if parameters[2].value: # If the password field is filled in gis = GIS(portal, user, password, verify_cert=False) serverList = gis.admin.servers.list() newList = [] for item in serverList: myString = str(item) newList.append(myString) parameters[3].filter.list = newList if parameters[3] in newList: b = newList.index(parameters[3]) return   ...

Thanks! After some tinkering, I've got it working. I can enter my portal url, user, password and I get a list of GIS Servers to choose for the 3rd parameter.   def updateParameters(self, parameters): """Modify the values and properties of parameters before internal validation is performed. This method is called whenever a parameter has been changed.""" # Create a dropdown list for the GIS Server Parameter of all federated GIS Servers portal = parameters[0].valueAsText user = parameters[1].valueAsText password = parameters[2].valueAsText if parameters[2].value: # If the password field is filled in gis = GIS(portal, user, password, verify_cert=False) serverList = gis.admin.servers.list() newList = [] for item in serverList: myString = str(item) newList.append(myString) parameters[3].filter.list = newList   One issue is I am using the ArcGIS Python API in line 11 to get a List of GIS Server. If I pass that list directly into my Filter List  my toolbox throws this error.    ValueError: FilterObject: illegal list value   Turns out I need to convert each item in my serverList to a string and add it to a new list. Then, using the new list, my toolbox dropdown works correctly.  Say the user selects the 2 item in the dropdown (index 1), how I store that index number as a variable in my updateParameters function and use that in my execute function later? ...

I see. Good to know, thanks! ... View more

@Anonymous User I'm attempting a python toolbox for the first time and hitting a wall. I would like the enter the Portal URL, username, password and have the GIS Server parameter auto populate with a drop down list of all my federated servers. If I comment out the updateParameters method, then I can enter the other parameters without the error.

Thanks I will look into this. Sounds like I will need to use a Python Toolbox over a Script Tool.  ... View more
