Disappearing labels....bug???

Anonymous User — Sat, 11 Dec 2021 06:09:40 GMT

I'm having a strange problem with a script. I have a template MXD set up with a bunch of text elements set up that I will be updating by adding values from a search cursor. The script is to generate a soils by parcel report for non-tillable vs tillable Ag Land with adjusted CSR (Corn Suitability Rate) values. Everything in my script works correctly except that all the labels (except roads) disappear when the map is exported to a PDF.

I cannot find anything in my script that would be causing the labels to disappear. My first guess was that it had something to do with updating a bunch of text elements, but I ruled this out when I exported 2 PDF's (a test map BEFORE updating text elements and then the final version). Labels were not present in both PDF's. To update the text elements, I just created a dictionary where the text elements are the keys, and I add values from a search cursor on the selected parcel by concatenating the value to the original text element for the report. All my text elements come out correctly but no labels on the map. I am thoroughly confused. Here is my script:

I am attaching a before png of what the template mxd looks like (with all the labels) then the final product after I run the script and all the labels disappear. I have tried everything I can think of and no matter what I do the labels are disappearing. I have brought this to the attention of an Esri Analyst, but I do not think they have found a solution yet either... Has anyone else had this problem?

ArcGIS Standard 10.1 SP 1, Windows 7 64 bit SP 1

EDIT: In case anyone is wondering why the placement of text elements/data frames is slightly different between the two maps it is because I tested this with several different versions of the mxd in case the original was somehow corrupted, but I got the same results on the test mxd as well.

It appears that there is a bug associated with using Python label expressions...This is what was causing my labels to disappear. VB versions of the label expressions of the labels work fine...I do not know what in particular it was that was causing the issue, I have been using Python label expressions since I upgraded to 10.1 and until now have never had this issue. I will post the NIM when it is created by Esri in case anyone is interested/having the same problem.
