I have an inherited Mac, 4D v15.4 database where a certain interprocess variable was unexpectedly undefined. Then one method said it could not be executed. After setting a couple of key trace statements, I noticed that the variable was not populated (the smoking gun) and that "External Call Back” was part of the call chain. So, what could be the culprit here?

Note: part of the data from parameter $3 was redacted.. Method cannot be executed error that starts to process and reports “User Cancelled” which is not true... https://www.dropbox.com/s/aqxh1w7swwvj6ic/Screenshot%202017-04-07%2022.06.31.png?dl=0 <https://www.dropbox.com/s/aqxh1w7swwvj6ic/Screenshot%202017-04-07%2022.06.31.png?dl=0> Thanks, Robert ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
