Comment 24 Marek Fukala 2008-08-28 16:23:22 UTC 
It looks like there isn't an instance of JspContextInfo registered in the filesystem in folder
J2EE/JSPSyntaxColoring/<the passed fileobject mimetype>.

For text/x-jsp and text/x-tag we provide our own impl delegating to the jsp parser. For other mimetypes it is up to the
lang. support provider.

For now I have improved the exception so its message contains information about the passed fileobject and its mimetype.
Then, one someonw reports the issue on a build with the fix, we can investigate more.

Possible solution would be a fallback to the default jsp parser based implementation, but I would prefer to know the
real reason first.

I'll do the fallback + logging of the errorneous state if noone reports the issue on lastest build in a week.

Comment 32 Marek Fukala 2008-09-12 14:58:40 UTC 
I can reproduce the problem with dragging and dropping the file node if the file is opened in editor. Thanks.
Comment 33 Marek Fukala 2008-09-12 17:26:55 UTC 
At least partially fixed the problem. JspSyntaxSupport holds a reference its document fileobject. When the file is moved
or somehow else invalidated and the document still exists the invalid fileobject may be passed to the
JspContextInfo.getContextInfo() which will then throw the exception since the invalidate fileobject mimetype is
content/unknown.

The fix ensures the fileobject backing up the document is always fresh or null.

The fix mainly solves the reports where SimplifiedJSPServlets plays its role. 

I am not completely sure if the other reports (e.g. editing a Facelets template (XHTML) in WEB-INF/templates) are the
same case.

I'll close the issue and we will see if anyone again complains about the problem (will be in fact different issue that
the one just fixed, but with similar effect).

Comment 36 Marek Fukala 2008-10-16 14:29:29 UTC 
rajivderas, did you do some changes in resolving mimetypes? Can you please specify what did you do when the exception
appeared? From the error message it is clear that your .jsp file is resolved to text/xml mimetype.
Comment 37 rajivderas 2008-10-16 14:32:06 UTC 
i went to the jsp file property pallet and entered */ in to the name field property then i came to the jsp editor and 
tried to format the file and boom
Comment 38 Marek Fukala 2008-10-16 16:07:00 UTC 
thanks, I can reproduce the issue now.
1) open a JSP file
2) open properties window
3) select name property
4) type */ and press enter
=> the file name is changed to .jsp
=> the reported exception is thrown
=> the file has text/xml mimetype
=> no jsp features works

Lowering the priority since the scenario is pretty uncommon.

As I can see it, there are several problems:
1) the property value accepts */ value and then incorrectly renames the file
2) the mime resolved doesn't resolve the file properly even the extension is jsp

this issue should not be marked as INCOMPLETE no more. 

I'm affraid with so many duplicates it is not an "uncommon" scenario - probably there are more ways how to reproduce 
the problem
Comment 43 Marek Fukala 2008-11-25 13:45:55 UTC 
IMHO the problem is in the property editor allowing the simple slash as a new value. Then the file becomes .<extension>
so the extenstion is not considered as extension but as a filename. FileObject's mimetype then changes to
content/unknown and many features stops working besides the file becomes hidden in the explorer views.
Comment 44 Jiri Skrivanek 2008-12-06 08:54:17 UTC 
I added a check to avoid slashes in filename for rename. I also added Utilities.isJavaIdentifier check to
JspDataObject.handleRename. Please, review if it is appropriate.

This issue was originally marked as duplicate of issue 128818, that is already fixed. This issue is still valid, so this seems to be another issue, but it might be related.
