It works for me.
Give us an actual scenario to test.
Putting in text, doing a search...finds stuff.
I am on windows 7, 32bits, jdk 8-025.
open a brand new sheet, or an existing script, search for any existing text, finds nothing (cursor does not move, no text highlighted)
it looks that what happens is that options selected in a pl/sql editor act globally. I had "Selected Text Only" in such a window, and then search does not work in a worksheet where I have no active selection. It works again if I unselect the option from the pl/sql editor.
That's definitely a bug, those options shouldn't be tied together.
Nice catch indeed.
These settings are saved globally and there is a logic error in that the UI component is unchecked and disabled but the actual find option is not changed.
As a temporary work-around, you can select text in the worksheet, and then ctrl-F to see / reset the selected text search value.
Fixed. WIll be available in next release.
As part of this, the Worksheet has been modified to use the same find mechanism as the procedure editor. This also fixes an issue with go to line in the Worksheet.
