Open a SQL Worksheet in SQL Developer.
Require the same change on many lines.
Setup SQL Developer to launch and External Tool (SQL Developer.Tools.External Tools). Notepad++ in my case.
Everything works great EXCEPT when finishing editing in External Tool, close file in External Tool and save.
Go back to SQL Developer. Changes are not updated.
You must toggle to any other open application, then back to SQL Developer.
Now changes are reflected.
Changes should refresh as soon as file is closed/saved in External Tool.
I have not tried with any other External Tool - SQL Developer only.
It worked this in previous and current version of SQL Developer:
PREVIOUS: 4.0.0.12 Build MAIN-12.84
CURRENT: 4.0.0.13 Build MAIN-13.80.
Thank you.
