Description hklerks 2003-10-15 15:10:21 UTC 
Under certain circumstances, the I18N wizard 
throws a NPE whilst processing selected source 
file(s):

Annotation: Exception occurred in Request 
Processor

Note that individual internationalization of each 
file in the selection works OK (which IMO rules 
out the content of the files at hand).
Comment 1 Marian Petras 2004-03-04 17:49:18 UTC 
The problem seems to be in module Editor. In the stack trace, the last
call initiated from module I18n is

     org.netbeans.editor.BaseDocument.remove(int, int)

which should should check the passed parameters and throw a
BadLocationException if there are wrong (module I18n would display an
error message dialog then). Since this was not the case, the problem
is somewhere else.
Comment 2 Miloslav Metelka 2004-03-04 18:15:09 UTC 
There appears to be null stateInfo in a non-first line element.
Normally this should not happen but we should add a robustness check
for that situation.
Comment 3 Martin Roskanin 2004-09-01 16:09:24 UTC 
should be fixed in [maintrunk]
Affected code has been removed as a result of issue #44693 fixing...
