Unable to close file

Submitted by kbs on Wednesday, 18 November, 2009 - 18:59

I installed the r.xml mode file and then tested it by opening a file with .R extension. The syntax highlighting worked just fine, so I thought I did the installation correctly, but now I'm unable to close that file, exiting jedit and re-opening doesn't help, the file is still open. I get this error message:

delegate?

by Robert Schwenn on Wed, 18/11/2009 - 20:47

Check Your r.xml for a tag with an DELEGATE attribute like this: DELEGATE="filename::rulesetname"

In this case the "filename.xml" must exist an in this file a ruleset "rulesetname" has to be declared, because it is referred.

I'm brand new to using jedit,

I'm brand new to using jedit, so maybe I didn't understand your instructions correctly. I opened r.xml (not in jedit since that didn't work -see below) and searched for 'delegate', but it does not occur in the file.
Also, the problem seems to have morphed. Now when I open any file (including r.xml) in jedit i get a blank document. The correct filename is shown on the top but the page is just white and I get an error message when I try to open a new file.

settings directory

Maybe, You first should try to delete Your settings directory (see http://www.jedit.org/users-guide/settings-directory.html). Sometimes this let problems go away.

If this wouldn't help, then remove the "r" mode and look what happens...
