Description Jiri Skrivanek 2007-09-07 09:40:30 UTC 
NullPointerException is thrown when you editing RHTML file. I can reproduce it beta1 200709070000 and because it breaks
editing when it appears I recommend to fix it in beta branch. To reproduce:

- create Ruby Application
- open new file wizard
- choose Ruby|RHTML file
- go to the end of the file
- type <%= l
- type backspace until you remove entire previously typed text
- type <%= l

java.lang.NullPointerException
	at org.netbeans.lib.lexer.EmbeddedTokenList.createLexerInputOperation(EmbeddedTokenList.java:311)
	at org.netbeans.lib.lexer.inc.TokenListUpdater.update(TokenListUpdater.java:353)

Mila,
isn't this connected with fix of issue 114613 ?
Comment 3 Miloslav Metelka 2007-09-07 12:18:19 UTC 
I have finally reproduced the problem in the release60_beta1 branch. I had one debug turned on that caused the problem
to not appear.
The problem does not appear in the trunk likely because there is already a different version of HTMLLexer and JSPLexer
in the trunk.
It's in fact caused by issue 114613 but this one should be easy to fix compared to the whole scope of the 114613.
Comment 4 Miloslav Metelka 2007-09-07 14:26:40 UTC 
I have a fix, I'm just checking editing of various types. I will commit within 15 minutes.
