hello.tagx (391 B)

stacktrace.txt (6 KB)

test.jsp (266 B)

Simple jsp file (test.jsp):

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="foo" tagdir="/WEB-INF/tags/mytags" %>
<html>
<foo:hello>
  <jsp:attribute name="element">
    test {1+2}
  </jsp:attribute>
</foo:hello>
</html>

The referenced tagdir with one tagfile is trivial nonsense as well (attached).

I can consistently reproduce the "CompositeLanguageFileViewProvider.updateOuterLanguageElements" exception (see attached stacktrace), by following the next steps:
1) Navigate to line 2 ("<%@ taglib prefix="foo" ...")
2) Duplicate (Ctrl-D). Now we're on line 3
3) On the new line 3, change "foo" into "c"
4) Still on line 3, select the following text: tagdir="/WEB-INF/tags/mytags"
5) Delete the selected text, but don't change caret position
6) Invoke completion (you should see "tagdir" and "uri" suggestions), but do not choose any suggestion yet

After step 6, I get the mentioned error every time.
