    CC 2015.5 Scripting Bug

    JJMack Most Valuable Participant

      Several of may Photoshop do not work in CC 2015.5 because of a new bug in CC 2015.5 scripting support. While it easy for me to program around it because I know how it bites.   It could effect other script and go undetected for some time.


      I have created script the use the file info  instruction metadata for operation instruction.   The scripts add and remove their private information there.  The problem only happens when one of the script tries the remove its information it had added and that is the only data in the  instruction metadata.  CC 2015.5 fails to remove the data when the script set the field to empty to nothing.  Prior versions of Photoshop scripting worked correctly.


      Its is easy to program around all one need to is add garbage that will not be removed. the removing every thing else will work.  Here is a simple toggle center guide script shoe work in PS 7 with optional scripting Plug-in to CC 2015.   It will not in CC 2015.5.  However in you add something to the document info instructions it will start working on that document in CC 2015.5.
