XSLTC and ArrayIndexOutOfBoundsException

["Brian D. Kresge" <bk...@rochester.rr.com>]

Hi all-
I am hoping I am just missing something here.  I am very excited to be
working with XSLTC; as it alleviates alot of performance problems related to
XML/XSL transformations...

I am having problems with some of my XML/XSL combinations.  My initial
findings would seem to conclude that this problem manifests itself with
smaller DOM's, and the use of the XPath expression "//@some-attribute".  I
have attempted to document a very small test that I put together to
demonstrate the problem.

Something of interest; changing the line in the XSL "<xsl:value-of
select="//@attr"/>" has different (and unexpected) results:
1) Changing to "<xsl:value-of select="//Root/InnerElement/@attr"/>" returns
nothing (but no exception is thrown)
2) Changing to "<xsl:value-of select="/Root/InnerElement/@attr"/>" works


If anyone has any idea as to what I may be doing wrong, or if I have
stumbled over a new bug of some sort; I would be very appreciative.

Thanks,
Brian Kresge
