even after fixing http://netbeans.org/bugzilla/show_bug.cgi?id=210541 Studio IDE can not work with HTML files.

P1, because we still can not make Studio IDE workable and tests are failing.
changeset: 219605:642b75c7366c summary: #210541 - more robust code with respect to a CES redirectors No NPE should be thrown now, but if HtmlEditorSupport.getDocument() returns null due to a registered CES redirector which return null from getDocument() then the file encoding is not properly used when saving the document to the FileObject. I cannot reproduce the issue so I just guess it may be caused by a problem in the registered redirector. BTW do you mean CND distribution by "Studio IDE"??? Please give me more info how to reproduce or ideally create a complete failing unit test for me. Then I'll try to make more elegant solution, otherwise I cannot fix properly. Please reopen the issue then. Thank you for understanding.
BTW when the problem started to appear? I haven't done any change in the related code for long time so it may be caused by some platform (Jarda's) changes (not necessarily regression, could just reveal an old bug in html).
it appeared exactly after Jarda's fix of http://netbeans.org/bugzilla/show_bug.cgi?id=210541
