Description aldobrucale 2007-09-20 09:25:40 UTC 
I've opened in Netbeans 6.0 beta a C++ project which has been created with an earlier version of cnd using the "C++
project from existing code" option. My makefile includes a file that I'm trying to edit in Netbeans, but every time i
hit a key i get a very big error dialog. Frome the Netbeans log it seems that there is a problem with a file
"Services/IndentEngine/org-netbeans-modules-cnd-editor-makefile-MakefileIndentEngine.settings"

Comment 2 aldobrucale 2007-09-20 09:49:37 UTC 
It seems that the same happens every time I try to edit a file with an unknown extension. From the log file, it seems
that netbeans tries to instantiate an "org.netbeans.modules.cnd.editor.makefile.MakefileIndentEngine" class, but fails
because of the aforementioned settings file.

I can get it just typing in a Java (Form) file.  The warning popup every keypress is _EXTREMELY_ annoying.

Comment 5 Vladimir Kvashin 2007-10-16 20:37:26 UTC 
Just to clarify the situation:
This does not depend on the version of CND that created the project.
This depends on the version of the CND your userdir settings originate from

(Netbeans userdir is a directory that stores all Netbeans settings; 
by default it's ~/.netbeans/<version>, i.e. ~/.netbeans/5.5, ~/.netbeans/6.0, etc.)
Comment 6 Vladimir Kvashin 2007-10-16 20:48:32 UTC 
What is the version of Netbeans/CND you imported settings from?
I strongly believe it is a non-release version.

The situation does not repeat if the settings are created with *any* released versions (I tried cnd 5.5, 5.5.1,
5.5.1u1). The serialVersionUID that caused the issue was changed on October 28, 2006, during the 5.5 (the very first
C/C++ pack version) development. In 5.5 release it was the same as now.

So I believe your settings were created by a pre-release version.

I would recommend not to import settings created by non-release versions.
Comment 7 Vladimir Kvashin 2007-10-16 21:14:30 UTC 
The issue repeats only with settings created via non released version (prior than 5.5) of cnd.
The source of the issue is an error in 5.5 pre-release version (absent serialVersionUID) that was fixed in 5.5 release.
Comment 8 aldobrucale 2007-12-14 15:41:38 UTC 
Is there any way to get rid of this problem? I have installed Netbeans 6.0 and I'd prefer not to lose my imported
settings: is there anything I can edit manually in my user directory to avoid the serialVersionUID problem?
