Description Vladimir Voskresensky 2013-04-18 11:32:58 UTC
For some reasons in pure C++ NB I can not open occurrences found in FormFeed.java file, while in pure J2SE NB version I can not open occurrences found in FormFeed.c 
The problem is in TextDetail.prepareLine function
dobj.getLookup().lookup(LineCookie.class); returns null for FormFeed.java file, because instance of dobj is DefaultDataObject
Comment 1 Vladimir Voskresensky 2013-04-18 11:33:38 UTC
mentioned files are from issue #228557
Comment 2 Vladimir Voskresensky 2013-04-18 11:34:42 UTC
btw, FormFeed.txt can not be opened neither from C++ nor from J2SE versions
Comment 3 Vladimir Voskresensky 2013-04-18 11:35:20 UTC
Jaroslav, can you evaluate, please
Comment 4 Jaroslav Havlin 2013-04-18 12:00:26 UTC
When I try to open FormFeed.txt from the Favorites view, a dialog appears that says "This file appears to contain binary data. Are you sure you want to open it in the text editor?" That seems to be the problem. Maybe the line-feed character causes this, or maybe there are some other "suspicious" characters.
Comment 5 Vladimir Voskresensky 2013-04-18 12:19:02 UTC
in my case I do not see any dialogs at all. Just dbl-click and nothing happens
Comment 6 Vladimir Voskresensky 2013-04-18 12:20:29 UTC
and you are right. Dbl-click from Favorites asks mentioned question
Comment 7 Vladimir Voskresensky 2013-04-18 12:22:45 UTC
probably this time issue is in openide.text component (or who is owner of mentioned message?) and it just doesn't support \f ?
Comment 8 Vladimir Voskresensky 2013-04-18 12:23:25 UTC
I've checked and file doesn't have any other 'special' symbols, only FormFeed

Thank you, so form-feed is the only problem in the file.

Reassigning to platform/Data Systems.
Jarda, please check the patch. If it's OK, feel free to assign the issue back to me, I'll integrate it.
Thank you in advance.
Comment 11 Jaroslav Tulach 2013-04-19 04:27:08 UTC
Patch is OK, but it also needs an associated test case.
