Description Andrew Irvine CLA 2002-11-13 16:05:22 EST 
Eclipse 20021113

1/ Create a new project and a new class (did not update build path).
2/ Copy the source from an existing class into this file.  You can now choose 
to save or not.  Obviously there are compile errors.
3/ Now shift all code to the right, then shift back to the left

Comment 1 Lynne Kues CLA 2002-11-13 17:04:06 EST 
Reassigning to text component.  Invalid argument being passed in by the 
application.
Comment 2 Lynne Kues CLA 2002-11-13 18:45:38 EST 
I think this has to do with the text optimizations that are being done during 
shift-right/left.  If you shift > 20 lines at the end of a document, this is 
when the problem is occurring.  Are you generating the correct text 
changing/text changed events?  The caretOffset is out of sync with the document 
content and is leading to the error.
