Applies To
- ThingWorx Platform 7.4 SP4 to 8.4 SP2
Description
- LoadText snippet from ThingWorx is locking the file that was read and afterwards, the file cannot be modified
- Run LoadText against any text file stored in any file repository, and then try to perform additional actions against the file, like a delete (either via the Composer or directly in file explorer on the machine); file will be locked and cannot be deleted
- Unable to write to or delete a file from a repository after calling it in the LoadText service
- Example of code that is loading content of a file in a variable, and then modify the file:
Things["SystemRepository"].SaveText({ path: 'test.txt', content: 'text1' });
var content = Things["SystemRepository"].LoadText({ path: 'test.txt' });
Things["SystemRepository"].SaveText({ path: 'test.txt', content: 'text2' });
var content = Things["SystemRepository"].LoadText({ path: 'test.txt' });
Things["SystemRepository"].SaveText({ path: 'test.txt', content: 'text2' });
- Running above code, error is occurring:
Wrapped java.io.FileNotFoundException: ..\ThingworxStorage\repository\Repository_thing\test.txt (The requested operation cannot be performed on a file with a user-mapped section open) Cause: ..\ThingworxStorage\repository\Repository_thing\test.txt (The requested operation cannot be performed on a file with a user-mapped section open)
